If the source equipment clock rates are operating outside
the specification of the AV8 phase locked loop circuit you
may experience “a hissing noise” from the audio outputs.
In this situation it is advisable to switch the phase locked
loop circuit off of the input giving the problem. Using the
second page of the engineering menu select the input and
turn the PLL (phase locked loop) from AUTO to Off.
This can happen with Broadcast signals particularly from
satellite, cable or terrestrial digital TV.

AV8 Phono Board
Circuit Description
Refer to circuit diagram L870 sheet 1
The phono board is a simple single stage RIAA amplifier
and consists of two channels of high gain amplification,
and the ability to switch between moving magnet (MM)
and moving coil (MC) settings.
PSU
The unit derives its + 15V regulated rails from the unit it is
fitted into with only local decoupling capacitors on board.
Interface
The unit connects to the host unit via a 8 way connector.
Amplification
The left channel has designators beginning with 100, and
the right with 200. For the purposes of this description the
left channel will be described, as the right channel is the
same in all respects.
The amplifier is a small signal class A voltage feedback
amplifier with switch able gain. The input consists of an
actively loaded differential pair of very low noise PNP
transistors (TR106, TR107). These transistors are very
specific and should only be replaced with identical parts
with the E grade high gain. TR100 and TR101 form a
current source for the pair, which sets the quiescent current
for the entire amplifier. The active load consists of TR110
and TR111, which forms part of the differential current
mirror with TR112, TR113 & TR114. This differential
stage also has an active load (TR102 & TR103) to keep
gain to a maximum.
Both of these differential stages are designed to have as
much gain as possible to enable the single stage design.
The RIAA response is achieved in the feedback network:
C101, C110, C111, C112, C119, C120 and R115, R112.
C115 is used to correct between MM and MC gains as the
amplifier is non-inverting.
SW100 switches between MM and MC. Two poles of the
switch change between the different loading required for
each type of the cartridge: R108 & C109 for MM and
added in parallel for MC R104 & C108. The other two
poles change the feedback resister value to alter the gain:
R105 for MM and added in parallel for MC R123.
The DC offset is controlled by a non-inverting servo built
around IC100. The amount of servo current is different for
each gain setting via R111 (MM) and R124 (MC) so that
the low frequency high pass point remains the same for
both settings. However the high pass point for the circuit
is set by C113. This gives a warp filter, stops DC start-up
thumps from upsetting DC coupled circuitry and an
approximation of the RIAA/IEC curve (-2dB @ 20Hz)
The output is class A buffered by a dual mirror follower
(TR104, TR105, TR108, TR109). The quiescent current is
set by D100 and R118 and R119.
Closed loop stability is achieved with C16, C117, giving
symmetrical slewing capability.

ADC
Refer to circuit diagram L896 Sheet 2
The signals to the ADC are converted to balanced by the three
opamps that also correct the level to the input of the ADC so
that 2VRMS on the input of the first opamp provides a full-scale
input to the ADC. 2.45V p-p (Note: not RMS)
A bias is added to the incoming signal so that it can be input to
the ADC analogue section which operates on a single 5V rail.
The bias is generated by the potential divider R216 and R217
this is 1.75V it is amplified by 1.43 by the opamp to give
approximately 2.5V at the output of the opamps IC202 and
IC203.
The diodes D200, D201, D202, D203 prevent over voltage
signals from being presented to the input of the ADC, they do
not protect the ADC if one of the opamp fails, as the diode will
blow as well. The ADC itself is set to operate as a master for the
I2S interface and to have its internal high pass filter enabled.
Data is output from the ADC on pin 15, it also generates a bit
clock at 64xFS on pin 14 and a word clock at Fs on pin 13. The
master clock on pin 17 is an input and should be at 256xFs.
DAC
Refer to circuit diagram L896 Sheets 3,4,5,6
The DAC sheets are all essentially the same and so are only
described once below. The Sub DAC output has some minor
differences that are described in the text.
The DAC is a 24bit 192KHz part it consists of a serial interface
port, digital interpolation filter, multi bit sigma delta modulator
and stereo DAC. The DAC is in hardware configuration mode
(the control of emphasis and serial interface mode is set by
pulling pins high and low on the DAC). The serial interface is
set to I2S. The pins DM0 and DM1 control the de-emphasis
filters and are controlled via a serial to parallel latch (IC905)
connected to the micro.
DAC reset is used to initialise the part and is under the control
of the microprocessor via a latch (IC905), it is an active low
signal. DAC MUTE on the same latch is an active low signal
and forces a soft mute of the output of the DAC.
The serial audio data interface consists of the DAC I2S LRCLK,
DAC I2S BCLK and DAC I2S DATA.
DAC I2S LRCLK is the left right clock for the audio frames it
should be a square wave at the sampling frequency. The signal
is low during the left frame and high during the right frame.
DAC I2S BCLK is the bit clock for the data and data is clocked
into the DAC on the rising edge of this clock. The bit clock
operates at 64 times the left right clock.
DAC I2S DATA is the actual audio data it is should be
presented in I2S format that is one bit offset MSB first data of
up to 24bits. Each data frame consists of 32bits one offset bit 24
data bits and 7 empty zero bits. (If the actual data is less than 24
bits (i.e. from CD) the unused bits may also be empty zero.)
The output of the DAC is differential on the pins 16,17 for left
and 12,13 for right. This signal passes into a second order
multiple feedback type balanced to single ended filter. The filter
is a second order Bessel function with a three dB point of
approximately 75KHz. This filter has been reworked on the
Bass output to have a three dB point of approximately 300Hz to
reduce the HF noise introduced by the bass management section.
The filter is unity gain however the balanced to single ended
conversion introduces a gain of two. The output of the balanced
to single ended converter should be 2Vrms for a full scale input.
Following the filter is a buffer stage. The buffer stage performs
two functions, it is a virtual earth mixer used to mix bass
information into the other channels when a sub woofer is not
present. Switching the CMOS switch 74HCT4053 controls the
mix. The control of the CMOS switch is under microprocessor
control via a latch (IC904). The second function of the buffer is
to provide a ground sense to the Audio board. This allows the
two boards to be loosely connected via a high impedance
without introducing hum. The difference between the grounds
on the two PCBS is sensed by the positive input of the opamp
and added into the signal, this effectively removes any ground
variation between the two PCBS. The full-scale output of the
DAC should produce 2v RMS at the output of the buffer stage.
DAC performance specification
THD better than -95dB (0.0018%)
Noise level at output of buffer better than -100dB ref 2VRMS or
94dBV
Frequency response +/- 0.4dB 10Hz to 20KHz
The other components on the circuit are decoupling for the
DAC, OPAMP and CMOS multiplexer. VMIDR and VMIDL
are the output bias chains and should be at approximately half
the Analogue Voltage rail (2.5V). AVDDL and AVDDR are the
logic supply rails for the digital filter and the switched capacitor
filter.
DSP
Refer to circuit diagram L896 Sheet 7
This is the Digital signal Processor sheet. IC701 is the main
DSP it decodes the in coming data stream to provide the 5
channels of discrete audio from Dolby Digital, DTS or MPEG
encoded material or a matrix decode of stereo information to 4
or five channel. The decoded data is passed to the second DSP
IC702 that performs post processing on the signal, performing
the THX equalisation Tone controls and Bass management.
The signal arrives at the first DSP either on the SPDIF I2S
DATA line from the digital inputs or on ADC DATA 3.3V for
analogue inputs. The SPDIF chip generates the clocks for its
interfaces, and the master clocks as it is the system master. The
ADC generates its own bit clock and word clock from the
master clock it receives from the ADC. When the ADC is in use
the master clock is generated by an 11.2896MHz crystal
attached to the SPDIF receiver (IC803).
The audio data is passed between the two DSPS in a time
domain multiplexed form on the DSP_AUD0 line. The clocks
for this line are on DSP1_SCLK and DSP1_LRCLK. As six
channels are passed between the two DSPS the interfaces works
at 3x the normal I2S speed. (3x stereo channels equal to six
channels).
Audio data passes out of the second DSP IC IC702 to the four
DAC’s via the serial terminators on pins 41 40 39 and 3. At this
point the audio data is in I2S format. The DSP generates clocks
for this audio data on pins 43 and 42 these are re-clocked and
buffered by IC1102 and IC1100.
A system clock is passed to the DSP via pin30. This clock is
multiplied inside the DSP chip using a phase locked loop. The
phase locked loop filter (PLL) is made up of the components on
pins 33 and 32. A smoothed supply is provided for the PLL via
the ferrites L701 and L700.
Control of the DSPs from the micro-controller is via an SPI
(serial peripheral interface) and uses pins 6,7,18,19,20. SPI is a
Serial interface with clock (pin 7) and chip select (pin 18) in this
implementation the read (pin 6) and write (pin19) lines are
independent and pin 20 is the interrupt line.
Chips IC704 to IC708 are the SRAM and SRAM interface.
IC704 is a level shifter from the 2.5V out of the DSP’s to the
3.3V of the SRAM The components IC705 IC706 IC707 are
the address latch. The address from the 8bit port on the DSP is
latched through these three chips to form a 19 bit address for the
SRAM chip. IC708 is the SRAM chip. The SRAM interface is
used to provide the lip-sync function within the DSP.
SPDIF RST This is the reset signal, at power up it is held low to
keep the device in reset until the power is stable.
IC802 is the master clock buffer and fans out the master clock to
the other chips inside the product. Each line is series terminated
to reduce reflections on the line.
Microprocessor
Refer to circuit diagram L896 Sheet 9
This sheet contains the circuits for the H8S micro-controller.
The micro-controller has control of all the system functions via
its I/O ports.
UARTS
The RS232 port is connected to one (TXD1 RXD1) of the three
UART interfaces the other two are used for the serial VFD
display updates (TXD0, SCK0) and the control of the DSP chips
(TXD2, RXD2, SCLK2).
RS232 input is buffered via IC902, which generates and
receives the levels required for RS232 communication (+/- 12V)
INTERUPTS
Pins 33,34,37,38 are used as interrupts to the micro-controller.
Pin 33 is the SPDIF interrupt, Pins 34 and 37 are the interrupts
from the two DSP chips and 38 is the power fail interrupt.
RESET
The chip reset is formed using the Schmitt trigger inverters in
IC907 and the RC delay formed of C936 and R921. This is used
to latch the information on the program button through the dtype flip-flop IC908A. The reset is further delayed by the RC
C903 R916 then used to release the reset on the Microcontroller. This is so that the micro-controller mode (Program or
normal run) is set up before the reset is released on the micro.
DSP Clock
SPDIF
Refer to circuit diagram L896 Sheet 8
The SPDIF receiver decodes the in coming SPDIF data into an
I2S stream and extracts the clocks from the signal.
The SPDIF signal arrives at the input through the coupling cap
C824. The SPDIF signal is BIPHASE decoded to extract the
data and a PLL is synchronised to the left right preamble to
generate the system clocks. In the absence of an input signal the
chip switches over to the crystal oscillator on pin 21 this
assumes that the input is now coming from the ADC. In this
situation the only clock generated is the master clock, which is
used by the ADC to generate the clocks for its I2S interface and
by the DSPs to generate clocks at their outputs. If the system is
in Stereo bypass mode (i.e. pure stereo operation) OMCLK
STOP is used to shut down the crystal oscillator to reduce noise
in the box.
The phase locked loop filter is made up of C820, C821 and
R820. The supply for the PLL comes from P5VD via the local
inductor to give a local smooth supply.
The SPDIF chip is controlled via an SPI interface on pins
1,28,27,2,19. Data is received on pin 27 CDIN, transmitted on
pin 1 CDOUT, the clock is on pin 28 CCLK, Chip select is on
Pin 2 and the interrupt line is on pin 19.
SPDIS EMPH indicates weather the incoming signal has
emphasis or not. (Low = emphasis)
The clock for the DSP is generated from the Micro-controller
clock and is output on PF7/0.
This output is at 24.576MHz. The 24.567MHz clock is divided
by two by the D type Flip Flop IC908B. A 74LV74 is required
to provide sufficient speed to generate a 12.288MHz signal to
the DSPs. This output is under micro-controller control and is
shut off when the DSPs are not being used. (I.e. stereo bypass
mode and standby).
Static Port expanders
IC904 and 905 provide static control lines for the noise sensitive
parts of the circuit, the DACs and ADC. They are serial
programmed via a bit bashed SPI type interface. Q900 generates
a output enable low signal from the reset signal.
Buffers
IC900 is a level shifting buffer between 5V signals and the 3.3V
tolerant inputs on the micro.
EEPROM
A 8k EEPROM is used to store the configuration information
this is IC906 it is addressed using a bit bashed I2C interface.
Connectors
The three main control connectors are also on this sheet and
connect to the video SK900 audio SK902 and front panel SK
901 PCBs.
Power Supply
Refer to circuit diagram L896 Sheet 10
The power supply sheet contains the connectors from the power
supply.
SK1003 display supply.
SK1000 Analogue supply.
SK1001 Digital Supplies.
SK1002 Power supply control.
Each of the supplies that is used passes through a LC filter to
reduce any noise in both directions i.e. noise coming in from the
switched mode supply or noise getting out from the noise on the
digital board.
PSU Sync signal
The sync signal is derived from the I2S bit clock (64xFS) signal,
which is divided down by IC1001 and the appropriate output to
sent ( either 96KHz or 88.1 KHz ) to the PSU by the multiplexer
IC1002.
Voltage set and VFD HT shut down
Two resistors set the voltage the Switch mode supply generates
for the display R1008 sets the HT voltage to 36V and R1007 set
the Heater voltage to 5V.
To prevent anode stripping when the heater is switched off the
VFD display has a HT shut down this is performed by Q1000
which shorts the voltage set resistor R1008 to ground.
Regulators
Three regulators are used to provide secondary regulation for
the +/- 15V signal (it is already regulated to +/- 18V on the PSU
PCB) and the 5V analogue supply that is derived from the 18V
regulated supply.
The 2.5V supply for the DSP chips is derived from the 3.3V
supply by using the forward voltage drop of a diode. And a
negative 5V rail is generated using a zenner to provide the bias
voltage for the CMOS switches used in the bass management.
Re-clocking
Refer to circuit diagram L896 Sheet 11
The re-clocking of all of the I2S signals to the DACs is
performed by IC1102 which clocks them all through the d-type
flip flops synchronous to the master clock on pin 9. The Data
signals then go straight to the DACs via series termination
resistors. The Bit clock and word clocks are buffered by IC1100
to provide fan out to the four DACs each with their own series
terminator to reduce reflections.

AV8 Power Supply Board
The 40W Resonant supply is designed to produce
extremely low levels of conducted and radiated noise. The
supply is based around a discontinuous inductor current
single ended flyback topology with active clamp. The
active clamp eliminates the power losses normally
associated with RCD type clamps and also eliminates the
high voltage ringing waveform normally present on the
primary inductance. In addition current is transferred to the
output capacitors as a half wave sinusoid rather than a
triangle wave which would normally be expected from a
flyback supply. The sinusoidal current waveform into the
output capacitors results in reduced output noise with
attenuated high frequency response.
The PSU provides the following functionality
! Universal input voltage range 85V ac rms to
265V ac rms.
! Eight regulated supply rails.
The output voltages are provided as 3 groups of supplies.
! Digital supplies
The digital supplies are for use on non audio circuits e.g
microprocessor and similar circuitry, they are referenced to
DGND.

Note. The rated supply currents for the analogue supplies
are 300mA per rail. The +18V and –18V supplies are
provided by 3 terminal regulators which derive their
current from the +21V and –21V rails. The current ratings
can thus be written.
Sum of output current from +21V and +18V = 0.3A max
Sum of output current from -21V and -18V = 0.3A max
These supplies are floating to allow them to be configured
as positive or negative supplies to suit the particular
display used.
The outputs are semi-regulated by a zener/emitter follower
circuit. The Output voltages my be trimmed by addition of
resistors between the lines +40V_SET and +5V_SET.
Note. The +40V rail was originally to be set to +36V as
marked on the drawings but it was found that the display
was to bright and subsequently has been adjusted to +21V.
External Synchronisation Input
The free running frequency of the PSU is around 75KHz.
For applications which require synchronisation to a system
clock, the PSU may be entrained to an applied Sync signal.
The Sync signal should be between 85KHz and 100KHz.
The Sync signal is applied via line SYNC (SK8-1) and
should be a TTL level 50%duty cycle square wave.
External PSU Kill Signal
For applications which require a means of shutting down
the PSU (e.g. in the event of a detected fault scenario) then
PSU latched shutdown may be initiated by pulling and
holding line PSUKILL* to DGND. The PSU will enter a
latched shutdown state after around 1second. The Latched
shutdown forces all output supplies to 0V and can be
defeated only by removing the mains input to the PSU for
>15seconds.
Under-voltage lockout
The PSU is protected against the input voltage being too
low (which would otherwise cause the input current to be
excessive for a given output power). In the event of the
input voltage being <75V ac rms then the PSU control IC
will disable gate drive signals and the PSU output voltages
will fall to zero.
Output Over-voltage Protection
The output voltages are monitored and in the event of the
output voltages rising approx 15% above specified limits
for >0.5 seconds then a latched shutdown event will be
triggered. This mechanism is not intended to protect
sensitive components from damaging transients but is
intended to protect the PSU and its load in the event of the
feedback signal failure.
In this design both the 3V3 and +5V are sensed. In the
event of a failure in e.g. the 5V rail then the feedback loop
will try to make the other rail voltage high enough to
supply all of the feedback current which the other, now
broken, supply was formerly contributing toward. This
would normally force the 3V3 supply to more than twice
its expected value (and all of the other supplies would be
multiplied by the same factor). The provided mechanism
prevents this eventuality.
AGND and DGND are joined together at 1 place on the
PSU (LK1)

In the event of the feedback loop failing (eg. due to a
broken feedback component) then the supply will enter

Overcurrent Protection
Figure 2
A number of mechanisms protect the PSU in the event of a
short circuit or very high load being placed on one of the
outputs.
These waveforms are for a non resonant ordinary
discontinuous flyback supply to illustrate the operation of
the circuit. The drain waveform starts at the voltage on the
input capacitor C35 and falls to near zero when the mosfet
is switched on. When the mosfet is switched off the drain
voltage flies above the input voltage and produces the
ringing waveform as shown. The current then ramps down
into Cout. When the current has fallen to zero there is
again some ringing. The frequency of the ringing is
dependent on circuit parasitics.
The PSU has a power limit of around 45W. If an attempt is
made to draw more power than this then the PSU will
power limit. This will show up as a reduction in the output
voltages. This will in turn force the feedback loop to
attempt to demand more power throughput to correct the
low output voltages. The feedback signal will then trigger
the feedback loop failure mechanism which will then force
the PSU into latched shutdown if this persists for more
than around 1second.
Mains Present Signal
The PSU provides a signal MAINSOK* (active low when
mains supply is OK). This signal is provided as an open
collector signal from SK8-2. The signal will go high (via a
pull-up resistor external to the PSU) when the mains
supply is removed and will then provide > around 20mS
warning of the imminent collapse of the output rails.
The actual time between the rising edge of MAINSOK*
and the output voltage rails falling out of spec is dependent
on mains input voltage and output load current. The output
voltages will hold up longer when the load current is low
and the mains input is high. The 20mS hold up spec is
based on low mains voltage and full load.
Inrush current protection
The PSU has an NTC in series with the input reservoir
capacitor. When the supply is first powered up the NTC is
cold and exhibits a resistance of around 25Ohms which
limits the current into the capacitor and prevents damage to
the capacitor, fuses and mains switch. After several
seconds the NTC temperature rises to around 90C and the
resistance falls to a low value allowing normal operation.
PSU Over-temperature Protection
The PSU transformer is fitted with a one shot thermal fuse.
This opens at 120C and removes the supply to the primary
side controller. The thermal trip is taped to the outside of
the transformer so that it could in principal be changed.
The materials from which the transformer is constructed
are rated for operation at 130C and in normal operation the
TX surface temperature is < 90C.
Figure 1
This diagram shows a very simplified PSU block diagram.
Only one output is shown and the active clamp is omitted.
The basis operation is as follows.
At the beginning of the switching cycle the gate drive
signal to M2 goes high. M2 is turned ON and the voltage
across C35 is applied across the primary of L1. During this
stage the voltage on the anode of Dout is negative the
diode is reverse biased and no current flows in the
secondary winding. The voltage applied across the primary
causes the current in L1 primary to ramp up from zero.
When the control circuit turns off M2 by taking gate drive
low then the bottom of the inductor flies back above the
input voltage . This flyback action causes the output diode
Dout to conduct and current is transferred to the output
capacitor Cout.
The primary current can be viewed by looking at the
voltage across R30. The output diode current can be
measured by using a current probe around Dout or inferred
by looking at the voltage waveform across Cout. The
falling ramp should produce a small voltage ramp across
the ESR of Cout.
By considering the simplified circuit it can be seen that all
of the output rails are developed in the same way. The
output diodes provide current to the large reservoir
capacitors on each rail.

AV8 Display Board
Refer to circuit diagram L898 sheet 1
Introduction
The AV8 display board contains the front panel graphical
VFD display module, buttons, LEDs, remote IR receiver
and encoder.
The graphical VFD display receives data directly from the
micro on the digital board (via SK100).
Power Supply
The supply rails are supplied to the Display PCB Via
SK100 from the digital board.
Please note that the supply rail marked P36VF1 has been
reset to a voltage of +21volts, this is because the display
was found to be to bright when supplied with +36volts.
LEDs
These are driven using two 74HCT595 (IC101 and IC102)
output latches controlled via SK100 by the micro on the
digital board.
! LED 100 is a bi-colour LED and is used for
standby.
! LED 101 to LED 110 are function and source
indicators.
Remote receiver
The remote receiver (RX101) output is buffered via a
74HC14D (IC104) this is then connected to the digital
board via SK100 pin15.
Volume/encoder
The encoder (SW124) output A and B is buffered via a
74HC14D (IC104) as PHASE A and PHASE B to the
digital board via SK100 pins 12,13.
Keyboard
The keyboard is polled using a 74HCT595 (IC100), this is
controlled by the micro on the digital board which scans
the keyboard output.
Scanning sequence:
! The outputs of IC100 Q0 to Q7 are set low in
sequence
! The keyboard lines KB0, KB1 and KB2 are
read
When a key is pressed it will result in a low on KB0, KB1
or KB2.
The micro knows which output has been polled low
(IC100 Q0 to Q7) and which line is low KB0, KB1 or KB2
and therefore the intersecting point will represent the key
which has been pressed e.g. Q2 is polled low and KB1 is
read as low means that the “CD” button has been pressed.

AV8 Audio Board
Introduction
This board forms part of the AV8 Preamp Processor, it performs analogue input selection and routing of analogue
signals to the various outputs. There are four sets of outputs; main, zone2 and two tape loops “Tape” and ”VCR”.
Main and zone2 outputs have volume controls (either of which can be the source for the on-board headphone
amplifier). A gain ranging stage in the middle of the audio path sets the headroom of the signal chain and also
provides a feed to the A-D converter on the digital board.
Control of the board is via the host micro-controller on the digital board.

The main stereo inputs have 100pF NP0 capacitors to
ground to reduce any high frequency signals radiating
from the input cables which are connected to the unit.
This is an EMC preventative measure.
In addition to be able to select any particular input as the
source, the input impedance of each input connector was
required to remain constant regardless of whether it was
selected or not. Input selection is therefore performed
using a method called “virtual earth mixing”. Each input
can be switched to one of the four stereo busses via an
input resistor, or switched to ground
For simplicity consider only the main ANALOGUE L
MIX bus. Each input is fed onto the common bus via a
resistor and an electronic switch. The bus is the input to
an op-amp in an inverting configuration. The switch either
allows the signal through to the op-amp, or shunts it to
ground. The inverting input of an inverting configured opamp effectively behaves as a ground (hence “virtual
earth”), which is why the input impedance looks the same
regardless of the state of the switch.
In theory all inputs can mix into the op-amp
simultaneously, but the control software only allows one
input switch to connect to the op-amp at a time. If
multiple inputs can be heard simultaneously then there
may be a problem with the control logic (see L921 circuit
sheet 7), or the AUD SDATA line from the Digital board
may be latched high.
For the “ANALOGUE L MIX” and “ANALOGUE R
MIX” buses, the resistor is 15kΩ, for the other three buses,
the value is 100kΩ. The three 100kΩ in parallel with
15kΩ give a total input impedance of just over 10kΩ - the
minimum required for THX certification. These particular
values were chosen to maximise the noise performance of
the main stereo ANALOGUE L/R MIX buses, bearing in
mind that a larger value resistor has poorer noise
performance. The 100kΩ resistors feed into the op-amps
of the less critical audio paths for ZONE2 and the record
loops VCR MIX and TAPE MIX.
Input gain range
Refer to circuit diagram L921 sheet 3
The gain ranger sets the headroom for the A-D converter
(on the digital board) and for the rest of the analogue
chain. The aim is to set the gain such that clip is not quite
reached with the input of the unit receiving a maximum
signal.
Excessive headroom reduces signal-to-noise
performance unnecessarily. Left and right channels are
identical, therefore only the left channel will be described.
IC301A is the op-amp into which the input resistors feed
(described in Input switching above). R302 in the fixed
feedback path ensures the op-amp cannot go open loop,
causing it to latch into a power rail. C301 compensates for
small stray capacitances at the op-amp input, ensuring it
does not oscillate. Switching in R303, R304, R305 or any
combination in parallel with R302 sets the closed loop
gain with reference to the 15kΩ input resistor. IC302
selects which of the three resistors are in circuit. It is
controlled by the micro via control line demultiplexer
IC707. Several ranges, nominally +6dB, 0dB, -6dB and 12dB can be generated depending on the state of the
‘GAIN RANGE’ lines A,B & C as shown below.

IC301A output feeds into an inverting unity gain buffer
(IC301B) which is referenced to 0V_SIG. R315 links
0V_SIG to the ADC circuits on the digital board via
connector SK915.
External / internal multichannel & main
stereo input multiplexer
Refer to circuit diagram L921 sheet 2
This group of multiplexers selects the signals to be routed
to the output volume controls.
The three signal sources are:!
!
!
FROM MAIN GR(L/R)
stereo from the gain ranger
FROM INT MAIN(L/R)
multichannel from the digital-analogue
converters on the digital board
FROM EXT MAIN(L/R)
external analogue multichannel source
These are selected by one of three control lines from the
micro via control line demultiplexer IC707.

ANALOGUE TO MAIN
INT DECODER
EXT DECODER
The multiplexers (except for IC204) select the feedforward resistor in a unity gain inverting amplifier. Left
and right sub-circuits are identical, therefore only left
(IC201, IC203A) will be described.
When ANALOGUE TO MAIN is high, the signal from the
gain ranger is selected via R201. The feedback around opamp IC203A is more complex than a standard inverting
configuration. Capacitor C203 removes any dc content to
subsequent circuits. However, since capacitors have nonlinear characteristics which are undesirable and adversely
affect the sound, C203 is placed in the feedback path in
series with the feedback resistor R205 to compensate for
these errors. R204 is in parallel with C203 and R205 to
provide a local dc feedback path. Without this the op-amp
would be open-loop at dc and would therefore latch into
the power rail. C202 compensates for stray capacitance at
the input of the op-amp and rolls off very high frequency
gain to provide stability.
It is normal to see a few volts of dc offset at the output pin
of the op-amp. This is because of the high dc gain of the
circuit (1M / 15k ≈ 67 or +36.5dB). This dc offset could
be due to the input offset voltage of the op-amps
themselves (up to ±2mV for OPA2134, producing a dc
offset at the output of 134mV) or because of a dc offset
supplied by the signal source connected to the unit. In the
normal operating mode where the gain ranger is at unity,
the absolute maximum permitted dc offset at the input to
the unit is approximately 150mV. This would produce a
dc offset at the output pin of the op-amp of about 10.2V.
This would still leave sufficient headroom for a 2Vrms
audio signal on top of this offset.
The surround and sub channels (IC205/206/208/209) are
very similar to the left channel described above except for
the op-amp ground references being tied directly to
0V_SIG. External multichannel inputs (FROM EXT
MAIN L, FROM EXT SURR L, etc) have 100pF NP0
capacitors to ground as an EMC preventative measure.
Volume control and headphones
Refer to circuit diagram L921 sheet 5,6
Volume control is performed by a Burr-Brown PGA2310
volume control chip. This chip is pin and software
compatible with the Crystal Semiconductor CS3310
volume control chip. The only difference is that the
internal op-amps run off ±15 volts rather than ±5 volts.
The gain is under micro control with steps of 0.5dB. All
volume controls share data, clock and mute control lines
but have individual chip select lines. The volume of each
channel can be controlled individually. “Zero-crossing”
detect is permanently enabled on each volume chip to give
click-free volume changes. If, however, clicking can be
heard when changing volume, especially at higher levels,
it is likely that there is a dc offset into the volume control
chip. This points to an error in the previous stage which
should have removed all dc. The DCA XMUTE line is a
power-on mute with a time constant set by R703 and C701
(sheet7). The output op-amps (IC 502, 505 etc) are
configured to block dc and are inverting amplifiers to
restore the polarity of the signal as the volume control
chips are non-inverting.
Since all outputs are identical only the main left output
around IC502A will be described. IC501 is a self
contained volume control with non-inverting op-amp.
C501 prevents oscillation of IC502A. C507 blocks dc to
subsequent stages of the circuit but is in the feedback path.
This provides some compensation for capacitor nonlinearities. R527 provides a local dc path to prevent the
op-amp latching into rail.
R502 provides output
protection, limiting current in the event of the output being
shorted. R503 provides a weak 0V reference to prevent
the output floating. IC503 is a DG413 analogue switch
which acts as a mute under micro control via
demultiplexer IC708. The five DG413s play a vital role in
preventing thumps at turn on/off.
At power on, the MAIN OUTS ENABLE and ZONE 2
OUTS ENABLE lines are forced low in hardware, pulling
the output connectors to ground. The hardware control of
these lines is determined by an RC time constant (see
‘control lines from micro’ below for details). This
allows sufficient time for the micro to boot up and take
control of these lines.
At power off, the micro detects power loss and forces the
outputs into the mute (grounded) state. This prevents any
pops. However, if the DG413s were run directly off the
+/- 15V rails, the outputs were found to drift to a dc level
that tripped power amplifiers into dc protect. This was due
to the way the power rails collapsed. (The -15V rail
actually went slightly positive for a time causing the dc
output drift.) D506 and D507 isolate the output mutes
from the main +/-15V supply. C543 keeps the supplies to
the output mutes up until long after the main +/-15V rails
have completely collapsed. R537 and R538 are actually
capacitors to decouple both local supplies to ground.
D503 protects the output stage by shunting over-voltage
spikes to the power rails. (It should be noted that the
diodes are not power devices, therefore they are likely to
fail if a high energy pulse is fired up the outputs of the
unit.) C502 shunts any high frequency signals at the
output to ground to help EMC.
The source for the headphone can be from the MAIN
output (IC502) or ZONE2 (IC505). Selection is by
74HCT4053 multiplexers IC507 and IC508 under micro
control via control line demultiplexer IC708. IC509 is an
LM4880 headphone driver IC which runs off the +5V
(analogue) rail. Its supply is drawn through a 2.2ohm
resistor to try to provide some crosstalk isolation to the
input multiplexers +5V power rail.
Zone2 and record loop outputs
Refer to circuit diagram L921 sheet 4
The input switches on schematic page 1 mix onto a virtual
earth bus (ZONE2, TAPE OUT or VCR OUT). The
associated op-amps are found here. Zone2 (IC401) has the
same type of dc blocking circuit as described before for
sheet 2 of the schematics. Note however that the feed
forward resistor is 100kΩ. To maintain unity gain, the
feedback resistors R402 and R404 have been chosen such
that their value in parallel with 1MΩ equates to 100kΩ.
TAPE and VCR record outputs (IC402 and IC403) have
100kΩ as the feedback resistor in series with a 47Ω output
protection resistor. The outputs are capacitively coupled
without compensation with a weak 100kΩ pull-down to
0V_SIG to prevent the outputs floating off.
Control lines from the micro
Refer to circuit diagram L921 sheet 7
Control lines for individual switches etc are derived from
16-bit words sent as serial data to three sets of serial to
parallel latches (port expanders). In this way, many local
control lines can be provided whilst only using a few
micro I/O ports. The same data and clock lines also drive
the PGA2310 volume control chip. IC702 decodes chip
selects for the volume control and latch devices. On
power up, the contents of the latches is cleared using a
buffered R-C circuit (R703, C701, IC701E/F). This also
mutes the volume control chips. In practice however, this
latch clear and volume mute line is of limited use as the
+5V analogue supply collapses slowly. If the unit is
switched off and back on within a period of 5 seconds,
C701 will not have discharged via D701 sufficiently for
the input of Schmitt trigger IC701E to interpret a LOW
condition. The default power-on state for the volume
control chips mute in any case.
IC708 is a special case as it provides the control of the
MAIN and ZONE 2 OUTS ENABLE. These must be low
at power up to prevent turn-on thumps, due to the
initialisation time period of the micro this must be done in
hardware. C710 and R729 generate a line that is HIGH at
switch-on, which sets the output of the latch to tristate
(high impedance). R535 and R536 pull these lines low so
that the output mute ICs switch the outputs to ground,
theoretically keeping the outputs silent during power-up.
In practice a small tick may be heard because the logic
devices don’t begin to operate properly until they have a
few volts across them. C710 charges via R729 over a
period of approximately one second. The falling OE line
to IC708 enables the latch outputs, which have by now
been written to by the uC.
Power supply
Refer to circuit diagram L921 sheet 8
The board is powered from the +/-18V and +21V supplies
which are regulated using standard LM317T and
LM337Ts. IC801 is a voltage regulator and is set for
+15V. IC802 gives -15V and its output is also used to
derive -5.1V using a Zener diode. IC803 gives a +5V
supply. R806 is used to reduce the voltage drop across
IC803 and therefore reduce heat dissipation in the part.
General Overlay / Interconnections
Refer to circuit diagram L921 sheet 9
Switch SW901 allows a “ground lift” facility. 0V_SIG is
either isolated from the chassis or tied by R901 and C912
in parallel. Header SK917 connects to the headphone jack
board. R910 and R911 provide a switched 3.3V control
signal from a 5V supply back to the micro to indicate
when headphones are connected.

AV8 Video Board
Introduction
The L922 board is the video and I/O board for the AV8
preamp processor. This board and its snap off contain the
video multiplexing for composite, s-video and
component/RGB video switching as well as two On
Screen display (OSD) chips, one for the main room and
one for Zone 2. The PCB also has the SPDIF digital input
multiplexing, RS232 connector, 12V triggers for zone 1
and 2, RC5 input for zone 1 and 2, RC5 output and the
program button for reprogramming the micro controller
flash memory.
The main video signal is not fed via OSD chip, instead the
OSD signal is generated synchronised to the incoming
Video and then cut into the video using a high speed
multiplexer. The only part of the display that comes from
the OSD chip is the text and its background.
This technique avoids the whole picture going soft
whenever text is displayed however it introduces
significant extra complexity.
Video PCB Icons + Mechanical
Refer to circuit diagram L922 sheet 1
This sheet contains drawing symbols to enter items on the
run out BOM as well as the chassis fixing points and their
associated EMC decoupling capacitors.
Video Board Top
Refer to circuit diagram L922 sheet 2
This sheet shows the interconnections between the
different sheets within the Schematic Hierarchy. It also
shows the snap off for the Headphone connector.
Video Board
Refer to circuit diagram L922 sheet 3
This snap of PCB contains the composite video inputs the
composite multiplexer and the composite outputs and their
mute circuits. The video inputs are 75R terminated then
AC coupled to the inputs of two RHOM BA7625 5 : 2
multiplexers. These multiplexers have a gain of 2 (i.e.
6dB) expect to be AC coupled at the input and DC coupled
at the output, if the input is inadvertently DC coupled it
will shut down as the bias network will not operate. This
could happen if any of the coupling caps are dc short at the
input.
IC 200 is the main signal path multiplexer. Output 1 from
the main multiplexer IC200 goes to the main PCB via the
buffer IC203 and SK209 to the OSD chip. IC 202 is the
VCR videotape loop it is buffered by IC203 then AC
coupled and connected via a 75R series termination
resistor to the RCA phono connector SK201.
IC201 is the Zone 2 multilexer output one from this is fed
via the buffer IC203 and SK209 to the main PCB where it
goes to the Zone 2 OSD chip.
The Buffer chip IC203 is a BA7623 video driver chip from
RHOM, it expects to be DC coupled at the input and AC
coupled at the output. If any DC current is drawn from the
output the chip will shut down as the output bias network
will not work. This could happen if any of the output caps
are DC short.
The monitor 1 and 2 outputs and the Zone 2 output are fed
directly from the main PCB via SK209 to the 75R series
termination resistors, after the termination resistors are the
mute transistors which pull to ground to shut down the
output. This only provides about 20dB of mute however
this is enough to shut down the sync so that a monitor will
not recognise that a signal is present.
The multiplexers are controlled via the serial to parallel
conversion latches IC204 and IC205. These are
programmed by a 16bit data word. The clock for the data
is (Video Serial CLK A) and the DATA is (Video serial
data A), once all sixteen bits have been clocked into the
latch the data is passed to the outputs by clocking the latch
signal video comp latch.
Screen Display
Refer to circuit diagram L922 sheet 4
This sheet contains; the on screen display chip for the
main zone 1, the input multiplexer for the onscreen display
chip to select which type of video source to send to the
OSD, the clock oscillators for PAL and NTSC generation,
the clock multiplexer to select PAL or NTSC for each of
the zones, the RGB output buffers and sync on green
insertion, a sync separator and mono-stable to generate a
black level clamp signal.
IC301 selects the input signal from the composite, S video
or Y/G inputs, this signal is buffered by Q300 divided by
two by the two 75R resistors then AC coupled into the
input of the On Screen Display chip IC302. It is also
possible to route the output of the OSD chip itself via this
multiplexer to the input of the sync separator so that the
black level clamp can still operate when the OSD chip is
generating RGB or YUV signals.
IC302 is the On Screen Display chip it generates the text
patterns which are multiplexed into the video using the fast
blanking signal. Fast blanking is asserted whenever there
is activity on the output of the OSD chip. The chip is
programmed via a serial bus made up of the lines Video
serial data, Video serial clk and Video serial cs. The
Horizontal line lock is performed by a Phase Locked loop
internal to the OSD chip the filter components for which
are R349, C349 and C350.
LESCREEN input sets the screen intensity for the
background and LECHAR sets the Screen intensity for the
Characters. The potential dividers on the pins define the
voltages.
The composite output of the OSD chip is sync tip clamped
by the circuit made up of Q302 Q304 and D300. This
circuit pulls the most negative part of the signal to a fixed
voltage, in this case approximately 0v.
The sync tip clamp works in the following way. A fixed
voltage of approximately 1.2v is generated by D300 and
the 4K7 current limiting resistor R343, this holds the base
of Q304 at 1.2v which in turn holds the base of Q302 at
0.6v. If the voltage on the collector of Q302 goes 0.6 v
below the voltage on the base (i.e. below 0v) the
darlington pairQ302 and Q304 turns on and dumps charge
on the coupling capacitor C348 until the voltage is
increased to 0v. So the most negative part of the signal
always remains at 0v, the most negative part of a
composite video signal is the sync and hence this is pulled
to 0v.
This sync tip clamp circuit is used for all of the composite
signals so they are all clamped to the same level. This
means that when the output of the OSD is switched into
the output the DC level does not change avoiding any
flickering or brightness changes.
The Y output is clamped to 0v at its sync tip by the
transistor Q301. This is an active clamp that pulls the DC
level to 0v every time a sync pulse occurs. The clamp
signal is created from the composite sync stripped by the
OSD chip IC302 this is the shortened to a ~700nS pulse by
the mono stable IC308. The time of the pulse created by
IC308 is set by R310 and C304. The clamp signal is also
used to clamp the incoming Y signal of both S video and
YUV signals. It is also used when the system is running in
RGB mode to clamp the RGB signals to black level.
The RGB output is used when the system is operating in
RGB mode and creates the colour information for the text
being inserted. The level is reduced from TTL levels to
video levels by the potential dividers that feed into video
buffers made from the opamps IC300 and IC303. A sync
signal can be added to the green output by activating the
output of the AND gate IC502. This raises the DC level of
the whole signal by 300mV then introduces 300mV syncs
to 0V.
The PAL and NTSC clocks are generated by the CMOS
oscillators. The oscillator is made by applying feedback
around un-buffered 74HCU04 inverters. The oscillation is
then buffered and amplified by some of the extra gates left
in the 74HCU04 pack. Both oscillators run at all times so
that the system can cope if Zone 1 is running NTSC and
Zone 2 is running PAL. Which clock is used for the zone 1
and zone 2 OSD chips is controlled by the Tri-state buffers
in IC305, these form a low noise 2:1 mux for the clocks.
RC5 I/O Triggers and RS232
Refer to circuit diagram L922 sheet 5
Sheet 5 has two RC5 demodulators made using IC400 and
IC401, one RC5 mixer and buffer, two 100mA current
limited trigger outputs, the RS232 output connector and
the program button for reprogramming the Flash memory
in the micro controller.
YUV/RGB Video Mux and OSD insert
Refer to circuit diagram L922 sheet 6
The circuit on this sheet multiplexes between the three
RGB/YUV inputs using the high speed multiplexers IC503
and IC505. Once the signal has been selected it is AC
coupled and DC restored using the active clamps
Q511,Q500 and Q512. (operation of this clamp is
described on sheet 4). The multiplexer following the DC
restore IC506 inserts text using the fast blanking signal
from the OSD chip. IC506 has a gain of 2 and 75R output
capability to drive the output directly.
The type of signal that is inserted (RGB or YUV) is
selected by the mux chip IC500A. The mux can select the
signals from the RGB buffers on Sheet 4 for RGB
operation or the Y output of the OSD chip and DC levels
generated by the potential divider R519, R500 and
R520,R522. These DC levels generate a blue background
for the text when it is not being overlaid on the incoming
video. IC501 switches between the blue background levels
and zero volts the signal CHAR OUT is active when a
character is present on the output and it is this that
switches IC501. The OSD B and OSD G signals are In a
logical AND with the Char Out signal to switch between
blue & white colour. When the circuit is set to blue output,
no green output & no char the colour is set to blue i.e it is
back ground.
In any other condition the colour is set to white because it
is a character i.e text is being displayed.
Zero volts is used when inserting characters as this
provides a colourless background. I.e. the characters are
white on a blue background.
Q503, Q504 and Q505 are used to mute the RGB output of
the unit when it is not in use and at power up.
SPDIF MUX and RXTX
Refer to circuit diagram L922 sheet 7
The circuit on this sheet multiplexes the seven SPDIF
inputs to a single line that is buffered and passed to the
digital pcb.
The input signals are 75 R terminated then AC coupled
into the multiplexer. The multiplexer is made up of The
2:1 CMOS switches IC600 IC601 and IC602.
The
multiplexer works in the same way as the audio
multiplexers. It switches the signal between the input to
the buffer circuit and a DC level at half the rail i.e. 2.5V.
Each multiplexer has a independent select line, only one
multiplexer should be selected at a time as the circuit will
mix the signal together if more than one is selected.
After the input signal has been selected by the mux it is
buffered and amplified by IC603. Applying feedback
around a 74HCU04 biases it into the linear region. The
three stages amplify the 0.5V P-P SPDIF signal up to a 5V
logic level. Two outputs are buffered off of this logic
level, one to go to the digital board the other is used for the
digital record loop.
The digital record output is driven by IC605 either the
buffered output of the input mux or the SPDIF output of
the DSP (from the ADC input) can be selected. The signal
is select by the lines SPDIF LOOP and SPDIF ADC TX.
The 75R characteristic impedance is formed from the
parallel combination of R613 100R, R626 680R and R627
680R. The digital output is AC coupled.
Control of all of the select lines for the Multiplexers and
Buffers is handled by IC604 and IC606. IC604 and IC606
are latched serial to parallel converters.
SVIDEO and CVBS OSD insert
Refer to circuit diagram L922 sheet 8
The circuits on this sheet switch the OSD generated test
into the incoming video. IC700 is the fast video switch that
inserts the text, it is controlled by the fast banking signal
directly out of the OSD chip. IC700 has a gain of 2 and
can drive 75R loads.
The composite video signal is sync tip clamped at the
input to the switch by Q701 and Q705 this works in the
same way as the Sync tip clamp on sheet 4 that operates on
the composite signal out of the OSD chip. These two sync
tip clamps ensure that the DC level is the same at the input
to the switch so that the text is switched in at the correct
DC level.
The S-video Y input is actively clamped by the clamp
signal as described on sheet 4. This ensures that the two Svideo Y inputs, one from the input source and the other
from OSD, are at the same DC level. Ensuring the DC
levels are correct means the text can be inserted at the
correct level.
The S-video C and OSD C signals do not need a DC clamp
as they will float to the same level due to the nature of the
signal.
S-Video Multiplexer
Refer to circuit diagram L922 sheet 9
This contains the multiplexing for the S-Video signals. It
operates in the same way as the composite multiplexer
(Sheet 3 Video board) except two multiplexers are used for
each signal to carry the independent Luma and Chroma
signals.
IC800 and IC807 carry the main feed Luma and Chroma
respectively. IC801 and IC806 carry the VCR record loop
Chroma and Luma respectively. The Main feed is buffered
by IC803 it then goes to the OSD insert sheet, the VCR
output is buffered by IC802 and then output to the VCR
connector.
Control of the Multiplexer is via serial to parallel shift
registers IC804, IC805 and IC808 these also have the
control lines for the SCART control signals, sync on green
and the Mute signals.
Zone 2 OSD
Refer to circuit diagram L922 sheet 10
This contains the OSD sync stripper and OSD insert
circuits for Zone 2. It works in a very similar way to the
circuits on sheets 4 and 8 combined together. As Zone 2
only operates in composite the circuit is without the extra
multiplexing for S-Video and Component signals.
The Zone 2 video comes from the video input sheet 3
buffer it is terminated on this sheet then fed to both the
OSD chip IC900 and the OSD insert multiplexer (Pixel
Switch)IC902. Characters are generated by the OSD and
this signal is present on the second input to the pixel
switch. Both of the signal are sync tip clamped by
transistors Q900, Q901, this means that their DC levels at
the input to the pixel switch should be about the same.
The fast blanking signal from the OSD controls the
position of the pixel switch. Fast blanking is high when
OSD characters are being generated this causes the pixel
switch to change to the output from the OSD chip. The
pixel switch IC902 has a video buffer output and a gain of
two. This buffered output is fed back to the Video board
(sheet 3) and out via the Zone 2 connector.
The vertical sync output of the sync separator IC901 is
used to determine if the incoming video is PAL or NTSC
so that the correct clock can be provided to the OSD chip.

AV8 Phase Locked Loop Board
Introduction
Refer To Block Diagram
The phase locked loop performs a comparison between the
incoming master clock from the crystal semiconductors
SPDIF receiver chip CS8415A and a locally derived
master clock from an xtal based Voltage controlled
oscillator (VCXO).
The comparison is made at Fs (44.1 or 48 KHz) rather than
the master clock frequency (256xFs) as this improves the
low frequency noise rejection of the circuit. The micro
controller on the main digital PCB (L896) knows what the
incoming frequency is and can select the appropriate Xtal
oscillator using the control lines XTAL11.2896 and XTAL
12.288.
The phase comparison is used to dump or source current
from an integrating circuit which filters the pulses and
converts the charge to a voltage to control the VCXO.
When charge is dumped onto the integrator the voltage
decreases (as it inverts) and this in turn reduces the reverse
bias across the voltage control capacitor (Varicap).
Reducing the reverse bias makes the depletion region in
the diode become smaller increasing the capacitance.
Increasing the capacitance increases the load capacitance
on the xtal oscillator and thus reduces the frequency at
which the crystal oscillates. (The circuit works in the
opposite manner if charge is sourced off of the integrator)
This is the method by which frequency lock is achieved.
The phase of the circuit is arbitrary as it uses two dividers
that generate the Fs signals.
The bypass circuit feeds the clock from the CS8415A
direct to the rest of the circuits in the event of any of the
following conditions.
! Phase locked loop cannot lock to the incoming
signal (i.e. it is not at Fs = 44.1 or 48KHz)
! To much jitter on the signal that it goes outside
the +/- 150PPM tolerance
! When the loop is actively locking onto signal
In the event that the circuit is knocked out of lock for any
reason more than three times after the DSPs on the main
board have been reset it defaults to staying in bypass. This
is to prevent the situation where the master clock is
repeatedly lost.
Description
Refer to circuit diagram L948 sheet 1
The master clock from the digital PCB L896 comes in on
pin 2 of SK3 goes to both the divider IC1 and to the
bypass circuit IC6. The divider divides by 256 and the
clock at Fs then goes to the Comp input of the Phase
comparator IC4.
As the integrator inverts the polarity of the control voltage
the inputs on the Phase comparator are swapped over so
that the comparison input is used for the main signal and
the signal input is used for the comparison input. This
corrects the polarity of the complete control loop.
The sig input on the phase comparator is fed from the
second divider IC2. IC2 divides the output of the voltage
controlled xtal oscillator by 256 so that it is also at Fs.
The phase comparator output PC2 generates a charge pulse
if the two signals are not exactly in phase and this pulse is
filtered and integrated by the opamp circuit IC5. IC5 runs
from +/- 12V rails so that the control voltage range can be
increased from 5V at the output of the phase comparator to
approximately 20V (+/- 10v) at the output of the opamp.
The increase voltage range allows a much greater
capacitance range to be achieved on the varicaps D1 and
D2. IC5 pin 3 is biased to 2.5 volts so that the 0 to 5V
input range can be converted to a positive and negative
output voltage.
IC5 Loop filter.
0V on the input = 10V on the output and 5V on the input
= -10V on the output
The DC control voltage from the output of IC5 pin 6 is fed
to the input of the varicaps D1 and D2. C31 and C35
provide an AC ground for the oscillator circuit.
R10,R11,C33,C40 and R12,R13,C38,C41 create a filtered
negative 12V bias for the diode so that a maximum
voltage of 22V (12V +10V) from opamp and a minimum
of 2V (12V –10V) can be present on the varicap.
The oscillator is a collpits type, the gain is provided by the
RF transistor Q1 and Q2. The oscillator can be turned on
and off by the digital transistors Q3 and Q5 this removes
the load from the emitter of the RF transistors. The output
of the oscillator is via the capacitors C50 and C51 after the
capacitors the signal is biased to the threshold point of the
following gates IC3A and IC3C. The gates amplify the
signal then the signal is fed back to the input of the loop to
the divider IC IC2 and to the input of a second buffer. The
second buffer is so that the micro can switch between the
original clock and the phase locked clock buffer. This is
achieved by IC3B and IC3D and the output (phase locked
or bypass) is fed back to the main digital PCB L896.
Q4 in the bypass feed is used to mute the input to IC3D
when the circuit is phased locked. This is to reduce any
cross talk from the original input master clock and the dejittered phase locked master clock.
Lock detection is performed using the PC1/PCP out
(PIN2) of IC4 the phase comparator. This signal goes low
whenever there is any phase error between the two
incoming signals so it can be used to determine if the
signal is in lock. When the signal is in lock this is always
high or has very small variations only due to tiny phase
error corrections. If the signals go out of lock the signal
goes low and the capacitor C12 is discharged fast via the
diode D3, to charge the cap up again the signal has to pass
through the resistor R15 so the circuit is biased towards
indication out of lock very quickly and only showing lock
when the signal has been high for some time. As the
output of the PCP is a 5V signal and the Schmitt trigger
IC7 is a 3.3V part a potential divider is used to reduce this
voltage to a maximum of 2.5V by R15 and R25. The
Schmitt trigger cleans up the edge of this lock detection
signal and buffers it to be fed back to the micro controller.
When the micro detects a lock signal it waits a further 3
seconds to make sure the lock is stable then checks the
lock signal again before switching from the bypass circuit
to the phase locked clock.
