2. MICRO CONTROLLER AND SMALL SIGNAL FUNCTION WITH TDA 9351:- This IC is a
combination of microcontroller and chroma (Small Signal function). This IC performs all important
functions in TV receiver. The details of IC are bifurcated in two parts. Small Signal function and
microcontroller
2A:- SMALL SIGNAL FUNCTION:
2A.1: VISION IF AMPLIFIER: The vision IF amplifier can demodulate signals with positive and
negative modulation. The PLL demodulator is completely alignment-free. The VCO of the PLL
circuit is internal, and the frequency is fixed to the required value by using the clock frequency
of the Controller/ Teletext decoder as a reference. The setting of the various frequencies (38,
38.9, 45.75 and 58.75 MHz) can be made via the control bits IFA-IFC in sub address 27H.
Because of the internal VCO, the IF circuit has a high immunity to EMC interferences.
2A.2: VIDEO SWITCHES: The video switch has one input for an external CVBS or Y/C signal.
The selected CVBS signal can be supplied to pin 38, the IF video output. The selection
between both signals is realized by means of the SVO bit in sub address 22H. The video ident
circuit can be connected to the incoming ‘internal’ video signal or to the selected signal. This
ident circuit is independent of the synchronisation and can be used to switch the time-constant
of the horizontal PLL depending on the presence of a video signal (via the VID bit). Because of
the availability of the Y/C input and the subcarrier output an external comb-filter can be applied.
In that case an external video switch (or comb-filter with integrated switch) must be used. The
subcarrier output is combined with a 3-level output switch (0 V, 4 V and 8 V). The output level
and the availability of the subcarrier signal is controlled by the CMB1 and CMB0 bits. The
output can be used to switch sound traps etc.
2A.3: SOUND CIRCUIT (QSS VERSION)
The sound IF amplifier is similar to the vision IF amplifier and has an external AGC decoupling
capacitor. The single reference QSS mixer is realised by a multiplier. In this multiplier the SIF
signal is converted to the intercarrier frequency by mixing it with the regenerated picture carrier
from the VCO. The mixer output signal is supplied to the output via a high-pass filter for
5
attenuation of the residual video signals. With this system a high performance hi-fi stereo
sound processing can be achieved. The AM sound demodulator is realised by a multiplier. The
modulated sound IF signal is multiplied in phase with the limited SIF signal. The demodulator
output signal is supplied to the output via a low-pass filter for attenuation of the carrier
harmonics. The AM signal is supplied to the output (pin 44) via the volume control. It is possible
to get the AM output signal (not controlled on amplitude) on the QSS intercarrier output. The
selection is made by means of the AM bit in subaddress 29H. Another possibility is that pin 35
is transferred to external audio input pin and pin 32 to (non-controlled) AM output pin. This can
be realised by means of the setting the control bits CMB0 and CMB1 in subaddress 22H.
2A.4: FM DEMODULATOR AND AUDIO AMPLIFIER (MONO VERSIONS):- The FM
demodulator is realised as narrow-band PLL with external loop filter, which provides the
necessary selectivity without using an external band-pass filter. To obtain a good selectivity a
linear phase detector and constant input signal amplitude are required. For this reason the
intercarrier signal is internally supplied to the demodulator via a gain controlled amplifier and
AGC circuit. The nominal frequency of the demodulator is tuned to the required frequency
(4.5/5.5/6.0/6.5 MHz) by means of a calibration circuit which uses the clock frequency of the
Controller/Teletext decoder as a reference. The setting to the wanted frequency is realised by
means of the control bits FMA and FMB in control byte 29H. When required an external sound
band-pass filter can be inserted in front of the narrow-band PLL. In that case pin 32 has to be
switched to sound IF input by means of the bits SIF (subaddress 21H) and CMB0/CMB1
(subaddress 22H). When the sound IF input is selected the subcarrier output or AVL function
are not available. From the output status bytes it can be read whether the PLL frequency is
inside or outside the window and whether the PLL is in lock or not. With this information it is
possible to make an automatic search system for the incoming sound frequency. This can be
realised by means of a software loop which switches the demodulator to the various
frequencies and then select the frequency on which a lock condition has been found. The
deemphasis output signal amplitude is independent of the TV standard and has the same value
for a frequency deviation of 25 kHz at the 4.5 MHz standard and for a deviation of 50 Khz for
the other standards. The audio control circuit contains an audio switch and volume control. In
the mono intercarrier sound versions, the Automatic Volume Levelling (AVL) function can be
activated. The pin to which the external capacitor has to be connected depends on the IC
version. For the 90 degree types the capacitor is connected to the EW output pin (pin 20). For
6
the 110 degree types a choice must be made between the AVL function and a sub-carrier
output for comb filter applications. This choice is made via the CBM0 and CMB1bits (in
subaddress 22H). When the AVL is active it automatically stabilises the audio output signal to a
certain level. The signal on the deemphasis pin (28) can be supplied to the SCART connector
via a buffer stage. It is also possible to use this pin as additional audio input. In that case the
internal signal must, of course, be switched off. This can be realised by means of the sound
mute bit (SM in subaddress 29H). When the IF circuit is switched to positive modulation the
internal signal on the deemphasis pin is automatically muted. The audio switch is controlled by
means of the INA/INB bits in subaddress 22H. It is, however, also possible to overrule the
audio switch position by means of the ADS and ADX bits (subaddresses 28H and 21H
respectively).
2A.5: SYNCHRONISATION CIRCUIT :- The IC contains separator circuits for the horizontal
and vertical sync pulses and a data-slicing circuit which extracts the digital teletext data from
the analog signal. The horizontal drive signal is obtained from an internal VCO which is running
at a frequency of 25 MHz. This oscillator is stabilised to this frequency by using a 12 MHz
signal coming from the reference oscillator of the micro controller/Teletext decoder. The
horizontal drive is switched on and off via the soft start/stop procedure. This function is realised
by means of variation of the T ON of the horizontal drive pulses. In addition the horizontal drive
circuit has a ‘low-power start-up’ function. The vertical synchronisation is realised by means of
a divider circuit. The vertical ramp generator needs an external resistor and capacitor. For the
vertical drive a differential output current is available. The outputs must be DC coupled to the
vertical output stage. In the types which are intended for 90 degree picture tubes the following
geometry parameters can be adjusted:
•
Horizontal shift
•
Vertical amplitude
•
Vertical slope
•
S-correction
•
Vertical shift
The types which are intended to be used in combination with 110 degree picture tubes have an
East-West control circuit in stead of the AVL function.
7
The additional controls for these types are:
•
EW width
•
EW parabola width
•
EW upper and lower corner parabola correction
•
EW trapezium correction
•
Vertical zoom
2A.6: CHROMA AND LUMINANCE PROCESSING: - The chroma band-pass and trap circuits
(including the SECAM cloche filter) are realised by means of gyrators and are tuned to the right
frequency by comparing the tuning frequency with the reference frequency of the colour
decoder. The luminance delay line and the delay cells for the peaking circuit are also realised
with gyrators. The circuit contains a black stretcher function which corrects the black level for
incoming signals which have a difference between the black level and the blanking level.
2A.7: COLOUR DECODER :- The IC can decode PAL, NTSC and SECAM signals. The
PAL/NTSC decoder does not need external reference crystals but has an internal clock
generator which is stabilised to the required frequency by using the 12 MHz clock signal from
the reference oscillator of the micro controller/Teletext decoder. Under bad-signal conditions
(e.g. VCR-playback in feature mode), it may occur that the colour killer is activated although
the colour PLL is still in lock. When this killing action is not wanted it is possible to overrule the
colour killer by forcing the colour decoder to the required standard and to activate the FCO-bit
(Forced Colour On) in subaddress 21H. The Automatic Colour Limiting (ACL) circuit
(switchable via the ACL bit in subaddress 20H) prevents that over saturation occurs when
signals with a high chroma-to-burst ratio are received. The ACL circuit is designed such that it
only reduces the chroma signal and not the burst signal. This has the advantage that the colour
sensitivity is not affected by this function. The SECAM decoder contains an auto-calibrating
PLL demodulator which has two references, viz: the divided 12 MHz reference frequency
(obtained from the microcontroller) which is used to tune the PLL to the desired free-running
frequency and the bandgap reference to obtain the correct absolute value of the output signal.
The VCO of the PLL is calibrated during each vertical blanking period, when the IC is in search
or SECAM mode. The base-band delay line (TDA 4665 function) is integrated. This delay line
8
is also active during NTSC to obtain a good suppression of cross colour effects. The
demodulated colour difference signals are internally supplied to the delay line.
2A.8: RGB OUTPUT CIRCUIT AND BLACK-CURRENT STABILIZATION : In the RGB control
circuit the signal is controlled on contrast, brightness and saturation. The ICs have a linear
input for external RGB signals. It is possible to use this input for the insertion of YUV signals.
Switching between RGB and YUV can be realised via the YUV-bit in subaddress 2BH. The
signals for OSD and text are internally supplied to the control circuit. The output signal has an
amplitude of about 2 Volts black-to-white at nominal input signals and nominal settings of the
various controls. To obtain an accurate biasing of the picture tube the ‘Continuous Cathode
Calibration’ system has been included in these ICs. A black level offset can be made with
respect to the level which is generated by the black current stabilization system. In this way
different colour temperatures can be obtained for the bright and the dark part of the picture.
The black current stabilization system checks the output level of the 3 channels and indicates
whether the black level of the highest output is in a certain window (WBC-bit) or below or
above this window (HBC-bit). This indication can be read from the status byte 01 and can be
used for automatic adjustment of the Vg2 voltage during the production of the TV receiver.
During switch-off of the TV receiver a fixed beam current is generated by the black current
control circuit. This current ensures that the picture tube capacitance is discharged. During the
switch-off period the vertical deflection is placed in an overscan position so that the discharge
is not visible on the screen.
2B. - MICROCONTROLLER WITH TELETEX DECODER: - The integrated teletex decoder
with embedded microcontroller is a control system designed for TV sets with analogue picture
and sound control. The system also offers an on screen display (OSD) and IR remote control of
all functions.
3. TUNER: - GDC Tuner EWT 5F3T1 is controlled by I2C bus through IC TDA 9361.The
tuning is based on frequency synthesis tunning.

having a feature of auto volume controller. Similarly stand by signal coming from
microcontroller is used to disable the sound out put from speaker.
7. VERTICLE OUTPUT STAGE:- The STV 9302 is a vertical deflection circuit can be used
for 90 degree and 110 degree deflection systems . One supply voltage for the scan is
required. The drive voltage is amplified by an amplifier. The supply voltage of this IC is 15
Volts.
8. VIDEO OUTPUT AMPLIFIER: The RBG output signal from TDA 9351 is applied to video
output amplifier section. IC TDA6107 or transistorized circuit can be used for video signal
amplification and to be applied to cathodes of CRT for generation of R, G, and B colors. If IC
10
is used, then internal amplifiers are used to amplify the video signal. The transistorized
amplifier can be designed by using transistor circuit in which 9 transistors are used. Chassis

constant to
superimpose red and blue horizontal
lines at the center of the screen. (See fig-04 & 02)
5.Adjust two tabs of 6-Pole magnets to superimpose
red/blue line and green one .Adjusting the angle
affects the vertical lines and rotating both magnets
affects the horizontal lines.
6.Repeat adjustments 3,4,5 keeping in mind red, green
and blue movement , because 4-Pole Magnets and 6Pole Magnets have mutual interaction and make line
