General Safety Information
1.3.1 Portable Operation
• DO NOT hold the radio so that the antenna is very close to, or touching, exposed parts of the body,
especially the face or eyes whilst transmitting. The radio will perform best if it is held in the same
manner as you would hold a ‘land’ telephone handset, with the antenna angled up and over your
shoulder.
•
DO NOT operate the portable phone in an aircraft. Switch off your telephone. The use of a cellular
telephone in an aircraft may be dangerous to the operation of the aircraft, disruption of the Cellular
Network may occur, and is illegal. Failure to observe this instruction may lead to a suspension or
denial of Cellular Telephone Service to the offender, or legal action, or both.
1.3.2 Mobile/Portable Operation - Telephone use in Vehicles:
• All equipment must be properly grounded according to installation instructions for safe operation.
•
Users are advised to turn off their equipment when at a refueling point.
•
Safety is every driver’s responsibility. Cellular telephones should only be used in situations in
which the driver considers it safe to do so.
1.3.3 General
• DO NOT allow children to play with any radio equipment containing a transmitter.
•
DO NOT operate this equipment near electrical blasting caps or in an explosive atmosphere.
Mobile Telephones are, under certain conditions, capable of interfering with blasting operations.
When you are in the vicinity of such work, look out for and observe signs cautioning against
mobile radio transmission. If transmission is prohibited, you must turn off your mobile telephone
to prevent any transmission.
In standby mode the mobile telephone will automatically transmit to acknowledge a call if it is not
turned off.
•
Refer to the appropriate section of the product user manual for additional pertinent safety
information
•
All equipment should be serviced only by a Motorola qualified technician.

•
In the WAP environment this is how the access is made.
1. The request for information is made in WML (Wireless Markup Language) derived from HTML.
2. Request is passed to WAP Gateway, which retrieves the information from the server in standard
HTML (which is then filtered to WML) or if available WML format.
3. The information is then passed the cellular user, via the cellular network provider.
•
There will be 5 Data parameters that the user will be able to edit:
-Baud rate - between 2400 and 14400
-Idle time out
-Line type
-Phone Number
-Connection type
•
For image download, the bitmap image will be downloaded as text and if the image is larger than
the screen then only part of the image will be displayed
• Ways to access Browser - Quick access key and Feature Menu
During browser mode, if incoming call is received then the browser will be paused with the user having
the option to resume after the call.
Calling Name Presentation - This is an improvement on the existing name presentation.
• At present name from phone book is displayed by comparing last 8 digits of Number
• New feature will show name as sent by the network. This is up to 80 characters, but will be
shortened to 12 for the phonebook.
• This functionality must be subscribed to with network.
• Caller can restrict this
• On call arrival phone Number is compared to phonebook if match is found but name is not
allocated then callers name will be stored.(However if there is any text against that number it will
not be overwritten)
Display Animation - Aimed at physically showing the customer is executing commands.
Existing animations are for Power up and Down sequences.
• New animations • Incoming / sending call
• Incoming / sending SMS
• WAP Browsing
Call Divert Interrogation - This function is just a more accurate way of ensuring that the caller is
diverted to the correct number, this is mainly achieved through the co-operation of the network
providers.
Connectivity – The t200 supports Windows 95 / 98 / NT in data service. No PCMCIA card is required

Testing on DM TOOLS
Below is the power up screen on selecting DM Tools.
File Types:
Boot file is of type .mot and the naming protocol is of the form r_amdt.mot
Flash file is of type .mot and the naming protocol is taken from the s/w version
As seen above 70131411.mot
Database file is a binary (.bin)type and the naming protocol is also derived from
The s/ware version e.g. 701314.bin
First select options from tool bar then:
Set comm port either 1 or 2 (the gray dot indicates selected port).
Set baud rate 19200 to allow flexing access.
Set eeprom mode default.
Remove charger jack from download box.
Note:
To upgrade the s/w from 701205 to 701214 you must use the database file, associated with the older
version (701205). So in the Choose Database File you would choose 701205.bin instead of 701214.bin
To then use flexing tools, the database should be changed to the later version, in this case 701214.bin
The software for the T205 is 7013xx and for the T200 it is 7012xx
The selection of the Boot file is as above
The Flash file is derived from the s/w version as above
29
of 51
GSM Field Service Support
T200 / T2688
The database file is a filename.bin configuration, and again is derived from the s/w version. (In this
case 701314.bin)
Selecting the Files option on the tool bar may change all the files.
Flashing Procedure STEP 1
After selecting the correct files, plug phone into cable but DO NOT power on. Then hit the download
button.
When you get to this point you have 10 seconds to power the phone on
If you don’t power the phone on in the 10 seconds then DM Tools will see this as a flash fail.
Assuming no problems the following screen should be seen during the flashing procedure
Screen dump during flash
The flashing procedure also flexes the phone. At the end of the download the following screen can be
seen.

RECEIVE
1. Received GSM 900 frequency enters the unit at the Antenna ANT1
2. L501 / L502 / L503 provide matching
3. The signal then enters mechanical Auxiliary RF port U113. When a load (50? is
placed into the socket the RF will be diverted into or out of U113). This socket will
be used for phasing, testing purposes.
4. From U113 Pin 1 to RF Switch U501 Pin 9 (ANT), where through control voltages
the Rx path is isolated from the TX path. The following voltages control the RF
Switch: VC1 – VC4, which are all 0V or 3.6V Low or High respectively.
The controlling input signals are:
? BS (Band Select), this signal determines GSM (Logic 0) or DCS (Logic 1) –
2.8V (originates as BANDSW from Gemini Pin 65)
? PA_ON, this signal determines if the TX burst is on progress (for use with the
RF Switch only) – 2.8V (originates as TXPA from Gemini Pin 119)
? VBAT, is the battery voltage and supports both U502 which is the Logic control
for the RF switch and the inverter IC501 - 3.3V – 3.6V
Below are the states of VC1 – VC4 and the relative states of BS and PA_ON for
each of the 4 scenarios.

5. The appropriate frequency is then fed out from U501 Pin 5 (GSM) GSM_RX or from
Pin 7 (DCS) DCS_RX.
6. The received frequency is then fed into a Dual Band select SAW (Standing Acoustic
Wave) filter U602 (Loss approximately 5dB). The GSM received frequency is then
applied to the base of Low Noise amplifier Q601, with input matching supplied by
C613 / L608 / C616 and the collector output matching elements supplied by C614 /
L607 / C606. The support voltage for Q601 and Q602 is from TX / RX IC U603 (see
Figure 1 for Block Schematic) Pin 3 (RFOUT ) and is 2.1V when active. The bias
voltage that is approximately 1.4V will be used to switch the correct LNA on or off
dependant upon band selected, or mode of operation.
Q601 and Q602 are switched independently dependent upon the mode of the phone to
save power, this is provided by the 3 signals RXON1, RXON2 and TXON, U603
Pins 44, 45 & 46 respectively. (These signals originate as RXON, CALBRA and
TXEN from Gemini, Pins 70, 69 & 118 respectively) The signal BS, U603 Pin 35
selects the current operating band of the receiver. In addition, these signals allow the
phone to go into ‘Calibrate mode’ in between Receiver timeslots to allow the gain of
the PGA (Programmable Gain Amplifier) (this is internal to the IC) to be adjusted. It

7. The gain of the Low Noise Amplifiers is approximately 18dB. The amplified signal is
then fed onto Dual Image rejection SAW (Standing Acoustic Wave) filter U601, an
identical filter to U602. (Loss approximately 2dB).
8. The output is fed out of the filter on Pin 7 for GSM and Pin 5 for DCS, as an
unbalanced output. The discrete circuitry C604 / C652 / C612 / L605 then split the
signal into 2 balanced signals. (at approximately +11dB of input signal)
Figure 1. U603 Block Schematic

Topaz T2688/T200, T2988/T205 L3 Circuit Description
9. The balanced signal is then fed into U603 Pins1&2 for GSM and Pins 47 & 48 DCS.
Within the U603 the received signal will now be mixed with the RX VCO to produce
the 1st IF Frequency of 225.067Mhz. This signal is out put from U603 as a balanced
1st IF output on Pins 42 & 43 (At approximately +25dB from input signal). These are
output on the signal lines MOX and MO.
10. The RX VCO frequency is generated by the RX Dual Band Oscillator U401, which is
controlled by the Frequency Synthesiser IC, IC401 (see page ??), this is fed into U603
on Pin 39 (LO1)
11. Once the 1 st IF frequency has been fed out, it is fed through Channel select SAW
filter U604 on Pins 1&2, and fed back out on Pins 7&8 the IF then re-enters U603 on
Pin 29(IFINB) and Pin 30 (IFIN). Internal to the U603, the 1st will now be downconverted to a 2nd IF.
12. The creation of the 2nd IF is achieved in the following way: A tuning voltage
IF_TUNE, is sent from the Synthesiser IC, IC401 which drives the Varactor D601, at
approximately 1.5V IF_TUNE will drive D601 to produce an output frequency of
540Mhz. This is then fed into U603 Pin 33.
13. Within the U603 the 540Mhz will be go through a ‘Divide by 2’ divider to give
270Mhz, this will be mixed with the incoming 1st IF of 225Mhz, to give a resultant
2nd IF of 45Mhz, this is then tuned by the 45Mhz tank Circuit consisting of C637 and
L616. The 45Mhz signal carrying the modulation, will then be fed into a phase
comparator, where it will be demodulated by a reference 45 MHz signal created form
the 540Mhz signal which has passed through the ‘divide by 2’ and then though a
‘divide by 6’ divider.
14. We now have our balanced demodulated RXI and RXQ signals, which are fed out on
Pins 20, 21, 22 and 23 are fed to the VEGA IC on Pins 51, 52, 53 & 54.
15. The VEGA IC is split into 3 sections:
? The Voice Processing portion of the IC includes the microphone and speaker
amplifiers, ADC and DAC, speech digital filtering and a serial port.
? The Base-band processing section includes a 2-channel uplink and Downlink
path, a serial port and a parallel port.
The uplink path performs GMSK modulation, D/A Conversion and smoothing
filters to provide the RF circuit with I & Q signals.
The Downlink path performs anti-aliasing (this is where we filter out signals that
are lower than our expected frequency, which are created through under
sampling.) A/D Conversion and channel separation filtering of the I and Q
signals. The serial port allows base-band data exchange with the DSP, with the
Parallel port controlling timing signals.
? The VEGA also performs auxiliary RF functions such as AFC (Automatic
Frequency Control) and AGC (Automatic Gain Control)

17. The RXI and Q signals from the RX/TX IC enter the VEGA IC (BDLIP / BDLIN /
BDLQP / BDLQN) and follow identical paths. The first stage is through a
continuous-time second order anti-aliasing filter, which serves 2 functions: 1) to
interface between RF logic and on-chip circuitry and 2) to prevent aliasing during the
ADC process.
18. The signal is then fed into a Sigma – Delta ADC sampling at 6.5MHz, and is fed out
as a 3-bit word. This is then fed into a set of digital filters, that will decimate (break
the signal into piece parts) to give us an overall sampling rate of 270.8KHz (? 24).
This gives us a low enough frequency for adjacent channel rejection and therefore
channel separation.
19. Calibration of the IQ paths is achieved by internally shorting out the 2 input I paths,
and then the same again on the 2 input Q paths the digital value measured will then be
stored in a register. Once the RXI and Q paths are reconnected to the circuitry, again
the calibration process takes place and the offset value is calculated.
20. From the VEGA IC, the information is looped through to the GEMINI IC on the
Base-band serial interface, consisting of BDX, (Base-band Data Transmit) BCLKX
(Base-band Transmit Clock) and BFSX (Base-band Transmit Frame synch). See
below for timing diagram:

21. Within Gemini general GSM processing takes place, such as:
? De-Interleaving : Interleaving is a way in which the information that is to be
transmitted is jumbled around before it is sent i.e.
If we wish to send the information ‘They must read this’
T H

R E

And we lose the information during the time
that ‘must’ is being sent. Then we will lose a
whole word.
However if we jumble the bits around that make up the words, i.e. transmit in a
different order.

If now during the same time frame we lose the same
amount of information, and then we will only lose a small
part of each word
?
Channel De-Multiplexing – this is where we decode the signal that was transmitted,
encryption at the transmitter ends is usually done by X-ORing the information.
?
Forward Error Correction Decoding – This is where the redundant bits of data that
were added in the transmitter are removed, and the information that is received can be
processed. The redundant bits are added in various quantities dependent upon the
signal quality. This means if some data is lost whilst travelling OTA then, for
example, instead of 8 bits of speech data being lost, only 4 bits of speech and 4 bits of
redundant data.
?
De-Segmentation and CRC Attachment analysis. – During the transmission
process the data is broken into packets of various lengths (No of bits). These packets
are then processed to give a checksum of what should be expected at the receiver.
Once in the GEMINI the information received is processed, and the two checksums
compared. From the analysis, the correct algorithm for repairing any data corruption
can be implemented.
22. The processed digital audio from the Gemini is then returned to the VEGA IC on the
Voice-band serial interface VDX (GEMINI Pin 85 to VEGA Pin 14) clock,
VCLKRX and Frame synchronisation signal, VFSRX.
6
Motorola Proprietary Information
Topaz T2688/T200, T2988/T205 L3 Circuit Description
23. The processed digital audio is received from the Gemini at 8Khz, from here the signal
is interpolated within a speech-digital infinite duration impulse response filter (IIR)
(i.e. that is, for the data coming in, the adjacent bits of the data being looked at are all
synchronised and an average taken. From this a prediction of events can be
calculated) also the sampling rate is increased to 1Mhz and the speech bandwidth is
limited by high and Low pass responses.
24. The signal is then fed into a Sigma-Delta Modulator for D/A conversion this will
then give a 1 bit over-sampled signal
25. This over-sampled signal (we over-sample to allow much cheaper and easier
reconstruction of the received signal) is now D/A’d and a high frequency noise tone is
injected into the signal. This noise will be used for programming the PGA. There are
7 programmable gains and 1 mute function.
26. The noise is then removed in a smoothing filter and the appropriate gains or
attenuations made.
27. The converted speech can then take 1 of 2 paths.
28. Path 1 to the Internal speaker LS1, the audio is fed out of the VEGA on Pins 32 &
33, and fed directly to the speaker, voltage suppressers U4 and U5 are responsible for
ESD protection. The speaker is situated in the front housing of the unit and is
connected to the main PCB through 2 contact springs.
29. Path 2 to an External Speaker, the audio is fed out from the VEGA IC on Pin 34
AUXO, it passes through Connector 3, J10 which is a jumper connector for JTAG
purposes. From here it is fed to Pin 4 of the External Connector J40.

30. There are 2 sources of input audio:
31. Auxiliary Microphone is fed in through J40 External Connector Pin1 and is fed
through Jumper Connector J8 (JTAG Use), and is amplified through the BQ5 circuit,
supported by the voltage DVCC. The input signal is fed onto the base of Audio
AmpBQ5, amplified, and fed out of the collector as AUXI.
32. The Internal Microphone X1, uses the circuit R14 / R15 / C22 / C23 / R17 / R18 to
provide microphone biasing, the biasing support voltage being fed from the VEGA IC
from Pin 26. (Gain approximately 27dBm)Voltage suppressers U48 and U49 provide
ESD protection to the circuit.
33. If both inputs are active then, output signal from the internal microphone will be used.
34. The input analogue audio is then routed to the VEGA IC Pins 28 & 29. Within the
VEGA the analogue signal will be driven through a PGA with a gain of between –
12dB to +12dB in 1dB steps.
35. A Sigma-Delta Modulator converts the signal from analogue to Digital, sampled at
1Mhz. The signal is the decimated and the sampling rate taken down to signal
samples at 8Khz.

36. Once again, as in RECEIVE, the loop between the VEGA IC and the GEMINI IC is
put in place for standard data processing.
37. The transmitted signal is sent to the Gemini IC over the Voice-band VDR Line
VEGA Pin 14 and is clocked by VCLKRX Pin 16. The signals are then received by
the Gemini IC on Pins 97 & 98 respectively. Synchronisation is achieved using the
frame synch signal VFSRX (VEGA Pin 13 / GEMINI Pin 96.
38. After processing, the Base-band signal information is transferred back to the VEGA
IC using the base-band lines, BFSR / BDR / BCLKR / (VEGA Pins 6, 4 & 5 and
GEMINI Pins 74 / 75 / 76 respectively)
39. Within the VEGA IC, the received information will now be modulated by GMSK.

Topaz T2688/T200, T2988/T205 L3 Circuit Description
40. The processed information is sent along the Serial Base-band interface, and is fed into
a register before being differentially encoded. The encoded signal is then applied to a
Sin / Cosine look up ROM where the GMSK TX I & Q ‘words’ are generated
(interpolation ratio of 16)
41. The I & Q words are the sampled at 4.33Mhz (16 X 270Khz) and applied to a high
speed 8 bit digital to Analogue converter, any image frequencies created during this
process will be removed by a subsequent Bessel Filter.
42. The burst length will be determined by the pulse width of BENA Pin 71 (when
BULON is active Pin 74, actual effective transmission burst length = BENA +32 ¼
bits)
43. Calibration of TXI & Q paths can be set during the BCAL timing window.
44. The analogue information, is now sent from VEGA Pins 57 – 60, to the TX / RX IC
on the TX I & Q lines Pins 13 – 16

45. The signal routing for the TX I & Q through the TX / RX IC is as follows:
46. The TXI & Q signals are routed to 2 modulators. At the same time, from the
Varactor D601, the 540Mhz signal, as produced in RECEIVE, is injected into the TX
/ RX IC on Pin 33, the signal is then amplified and divided by 2 (for GSM).
47. The 270MHz is then fed into a band select switch, and onto a phase splitter / shifter
which contains a 90o offset circuit. The resultant signal is then fed into the 2
modulators to be modulated by the TXI & Q data.

Motorola Proprietary Information
Topaz T2688/T200, T2988/T205 L3 Circuit Description
48. These 2 paths are then summed to give a single IF modulated signal, which is then
amplified.
49. From here the output current used to drive the TXVCO will be generated. The
feedback from the TXVCO (DCS or GSM) is mixed with the RXVCO frequency to
produce a reference frequency of 270Mhz. This is then mixed with the modulated IF
with the phase comparator giving an output proportional to the difference between the
phase vales of the 2 frequencies.
50. This output current is fed out on TX / RX IC Pin 11 (PLLOUT). R614 is used to
control the current out from PLLOUT.
51. The VCO driving current is then passed through the loop filter made up of R626 and
R627, C645 and C647. (C647 is a polyester capacitor used to ensure low noise). The
purpose of the loop filter is to prevent any overshoots due to channel changes, being
transmitted to the TXVCO. The TXVCO driving voltage is between 0.8V – 2.0V.
52. The drive current is fed into the TXVCO U606 on Pin 6, with the TX frequency
being fed out on Pin 1. The voltage TX2V8, which is switched by the signal
TXVCO_OFF, supports the TXVCO. The signal BS Pin 5 controls whether the
TXVCO produces a DCS or GSM output.
53. As the TXVCO produces both GSM900 or DCS1800 frequencies from the same
output line, the signal must be fed into a diplexer U605, this circuit uses inductive
properties to effectively delay 1 frequency compared to the other and therefore split
the paths, between the GSM and DCS frequencies.
54. The output frequency then takes 2 paths:
55. Path 1: The output signal is attenuated through R615-R622, coupled through C631
and C632 and fed into the TX /RX IC on Pin 8 (DCS) and Pin 9 (GSM). This will
then be used as the feedback for the TXVCO Phase lock loop as discussed in point
49.
56. Path 2: The signal is output as TX_GSM or TX_DCS to the PA.
57. The PA U201 is a Dual package three stage PA that is split into the GSM and DCS
part. The supply for the PA is VBAT 3.6V(depends on battery charge level) on Pin 6
(front stage) and Pin 8 (back stage).
58. Band selection is done with BS (Band Select). DCS high and GSM low level.
Signal inputs on pin 2 and 4 from the TXVCO diplexer U605 are TXDCS and
TXGSM. Amplified outputs are Pins 10 and 12.

59. Power Control is achieved in the following way:
60. RAMP is connected to the Gain Control circuit U202 Pin 3. This is the positive input
of the comparator. This is the same ideology as the AOC line in Whitecap products.
VBAT is connected to the negative comparator input on Pin 4 to compare changes on
the battery level that causes lower or higher gain of the PA
Output of the Comparator U202 is the signal APC (Automatic Power Control) Pin 1
that drives the gain input of the PA U201 Pin 14. This is fed through Q202, which is
implemented as a safety latch. In TX Mode, the right side of Q202 is biased on from
VBAT on Pin 4; this allows the APC voltage to vary the PA Drive.
In TX Background mode or RX mode, PA_ON is low, this shorts the left side of
R298 (VBAT) is shorted to Earth.
APC is also controlled in unison with the handset temperature. Thermister TR1
(which is supported by the voltage AVCC ) gives a voltage reading, which is
proportional to the current handset temperature. This is fed back to VEGA Pin 40. As
the temperature goes up the APC line is backed down slightly.
61. Sensing the high current flow to the PA back stage, Pin 8, controls the PA power
saturation. The Sense Resistor, R203 (0.033 ohm) is used to sense the voltage
variations on the VBAT line when the PA draws more or less current and is
connected to Pin 4 of Q201. The transistor is biased on using VBAT (Pin 5) and the
change in voltage over the sense resistor is throughput from Pin 4 to Pin 3. From here
it will vary the non-inverting input of U202 therefore changing the APC level.
62. Expected DC level at Pin 3 Q201 is 3.4V for PA off, 3.3V for Power step 15 and
3.2V for power step 5.
63. The second part of Q201 Pin 1 to 3 is used to inverse the TXON on signal as
TXVCO_OFF to switch Q603.
If TXVCO_OFF is low the TX VCO is on.
64. From the PA, the RF is fed out to the RF Switch U501 on Pins 1 (GSM) GSMPA, or
Pin 11 DCSPA. The operation of the RF Switch is explained in Point 4.
65. The appropriate RF signal will then be fed out to either the Antenna ANT 1 or to the
Auxiliary RF connector U113.
Synthesiser IC IC401
66. The synthesiser IC is responsible for outputting control signals to both the RX and
TX VCO’s. The IC is divided into an IF section Pins 2 - 7 and an RF Sectio n Pins 8 –
12.
67. Before any outputs from the IC can be used a reference must be made available. For
this we use the system clock. This clock is a 13Mhz clock which is generated in the
13Mhz crystal oscillator, the tuning voltage is generated as the signal AFC from the
11
Motorola Proprietary Information
Topaz T2688/T200, T2988/T205 L3 Circuit Description
VEGA IC and has a range of approximately 1.2V – 1.5V. The Oscillator supply is
generated from the Base-band Voltage Regulator U27 Pin 24 (VTCXO 2.8V). The
13Mhz is buffered by IC402 before being O/P as 13MHz to VEGA for use as the
system clock.
68. At the same time it is input to the Synthesiser IC on Pin 1 OSCin, from here the IF
tuning voltage IF_TUNE as spoken about in points 12 (RECEIVE) and 46
(TRANSMIT) to drive the 540 / 135MHz Varactor diode.
69. All the controlling signals for the IC are generated from Gemini and enter on Pin 14
DATA, the signals are clocked in (Pin 15 CLK) and the IC is enabled using the
control logic SYNPRG on Pin 13(LE)
70. The IF Support voltage for the IC is SYN2V8, a 2.8V support, generated in the RF
Voltage Regulator IC301 Pin 2 (OUTC). A sample of this voltage is taken to ensure
the synthesiser IC is switched off during idle time. This sample is fed into Pins 6 and
7.
71. The Feedback from the 540 / 135MHz Varactor diode is returned to the IC as the
signal LO2 and is fed in on Pin 3 (finif). To complete the phase lock loop.
72. On the RF side, the supporting voltage is again SYN2V8 and enters on Pin 11
(vccrf). The charge pump output for the TXVCO is fed out on Pin 8 (Dorf) to the
RXVCO U401 Pin 3. U401 is supported by SYN2V8.
73. The band select signal BS enters U401 on Pin 4 and will select the appropriate output
to either GSM or DCS on Pin 1. The output will then be fed out to the TX / RX IC as
LO1 to create the 1st IF, and also a sample will be fed back into the Synthesiser IC to
provide Phase Lock Loop feedback.
Power up Sequence
74. The main core of the power up sequence next to the operating software is the Power
Management IC U27. U27 contains 4 Voltage regulators.
? DVCC – 2.765V @ 100mA and provides the Base-band logic supplies. Pin 2
? AVCC – 2.765V @ 130mA and provides for analogue voltage supplies. Pin
27
? VTCXO – 2.765V @ 5mA – for use to drive the system 13Mhz clock. Pin 24
? VRTC – To charge to the Real Time Clock battery U32 (when battery voltage
falls below 1.2V). Pin 8
75. The battery voltage VBAT on Pin 1 supplies U27.
76. Once power is supplied to the unit, there are a number of ways that the unit can be
powered up. The input pulse is a 40mS +ve going pulse through U53 and U54 and
onto U27 inputs Pins 4&5,
12
Motorola Proprietary Information
Topaz T2688/T200, T2988/T205 L3 Circuit Description
These are:
? Power on generated by set alarm, which is generated from the RTC (the alarm
is set into the menu structure of the phone). U54 Pin 2
? IO2, software originated power on from Gemini Pin 112. U54 Pin 1
? From depressing the Power On key giving the signal PWR. U53 Pin 2
? From the External Charger (CHGERP). U53 Pin 1
77. As the unit begins to power up the reset signal is generated, again a +ve going signal.
Charging C57 generates the charge for the reset signal.
78. As for the GCAP the Power Control IC also interfaces with the SIM Card, VCC for
the SIM card is provided by Pin 20, onto SIM Block Pins 4 & 5. However the
occasional need for 5V SIM is provided using the input from the scaled DVCC on
Pin 17 and the charge pump C53 Pins 21 & 9.
79. Data is read from the SIM card on pin 2 of the SIM block I/O into U27 Pin 15 (IO)
and transmitted to the Gemini from U27 Pin 11 (S-IO). Also from Gemini are the
SIM CLK U27 Pin 13[in] & Pin 19 [out] (SIM Block Pin 1) and the SIM Reset U27
Pin 12 [in] and Pin 16 [out] (SIM Block Pin 3)
80. SIM I/O also ac ts as a SIM Presence detect signal.
81. Power for the unit can be taken from either internal Battery or from an external
source. The battery has 4 contacts, from battery connector JP2
? Pin 1 Supplies VBAT directly
? Pin 2 BATEMP is used to monitor Battery temperature during charging, and is
fed to VEGA for A / D processing.
? Pin 3 BAID is Battery ID and is used for the detection of different types of
batteries.
? Pin4 is ground
Alternatively the VBAT source can be taken from an external power source, this
originates at the I/O connector U40 Pin A3, with U36 providing ESD protection, the
signal is then fed as CHGERP, and through Fuse F1. As mentioned in Point 76 this
will ensure the unit powers up but will also pass through BQ3 and protection diode
D14 to provide VBAT. D15 limits input voltage to <6V
82. U30 is used to detect the charger and is supported by DVCC, once detected an
interrupt is sent to Gemini as IO9
83. For the Initial charge at low battery voltage, as before the input voltage at CHGERP
is approximately 6V,CHGERP originates at U40 Pin T3 with T1 as its respective
Ground
84. NOTE: If a desktop charger then I06 is used to communicate to the Gemini the status
of the charging indicator on the charger.

85. This will began to charge the battery through BQ3. (BQ3 fully open) The voltage
divider R111 and R112 puts a voltage of 4V onto the source of BQ6. During this time
C81 will be charged (approximate charging time is 3 – 5 Seconds.
86. When the charge in C81 reaches 4V the, the S-G bias on BQ6 will be 0V, which will
effect ively turn off BQ6, this in turn has the effect to switch Charging Control IC U29
off which will turn off BQ3.
87. For Normal charge the phased charging values stored in the EEprom will be D/A’d
then sent as signal IO11 which will control the gate of Charging Control IC U29
which will vary the gate of BQ3. This allows us to vary the charge onto the battery.
88. An exception to the above exists if a car kit is being used in which case, Ext. Power
will be input into the phone on the I/O connector Pin 11, with U19 provide ESD
protection as the signal IOPN11.
89. It will then be fed through Fuse F2, and onto the source (S1) of Dual FET U26, the
amount of current that is passed through to VBAT is controlled via software IO1 by
U25
90. For Power output when using the data cable, VBAT is fed onto the source (S2) of
U26, with U29 providing gate bias. D12 is forward biased for this 1 application.
91. The real time clock is generated by crystal X2 and runs at 32.768MHz. It is driven by
the charge pump from U46 Pin 1 (OSC1).
Synchronisation is achieved by IO14, which is clock generated by Gemini pin 50,
with the IC enabled by Chip Enable RTCCE Gemini Pin 117.
The re-chargeable RTC battery U32 provides power for U46. As mentioned in Point
74.
Pin3 nINT provides the alarm interrupt to power the unit on at a specified time.
92. U47 is the 1.8V regulator used to Power Gemini, supported by VBAT and is powered
on at the same time as the Power Control IC U27 (Pin 1 CTRL) and is supported by
VBAT. The 1.8V regulated voltage is fed out to the Gemini as PVCC18.
Memory
93. Flash U23 is split into Operating Software memory 12Mbit and EEprom Memory
4Mbit. Supported by DVCC on Pin G4. Chip enable NROMCS (N signifies active
low) from Gemini Pin 17 onto Flash Pin F1. Boot-code is contained within the IC
NFOE, Pin G1 (Active Low Flash Output Enable) is used to instruct Flash that
Gemini want to read or write form the device. DLPWR is not used.
94. SRAM U22 is a 2Mbit device, supported by DVCC on Pin E1. SRAM is Chip
enabled by NRAMCS Pin G3.

Display
95. The LCD module is a 98 X 64, Chip on Glass device and measures 37 x 33mm with a
polyamide foil connection to the PCB through U24. Support for the LCD is through
DVCC.
96. Contrast control is achieved by the variation in voltages, which are stored in C40
through C44 and DC / DC LCD driving voltages provided by C45 through C48.
97. Data to and from the LCD is though the data bus D0 – D7, U24 Pins 16 – 24
98. Chip select is sent from Gemini Pin 48 to LCD Connector Pin 28, with the Reset on
connector on Pin 27.
Vibrator and Alert
99. The vibrator is driven by the signal AAGC which originates from VEGA Pin 45, this
signal is applied to the base of Dual NPN / PnP transistor U44, this then causes the
second transistor to conduct forcing the collector high. This then effectively give s the
vibrator support voltage VBAT a path to earth through BQ1
100.
U6 provide EMF protection.
101. The buzzer / alert is operated, using the signal BUZZER from Gemini Pin 20,
this signal forces BQ4 to conduct creating the current path for the buzzer U8 support
voltage VBAT to earth.
102.
U7 Provides EMF protection for the buzzer.
Keypad and Back lights
103. The backlights are split into 3 for the LCD (D1 – D3) and the keypad backlights
of which there are 8 (D4 – D11). The backlights are switched on using the signal
LEDON (This is generated from Keypad detect switch U34 and is switched by the
signal B L from Gemini Pin 134. LEDON then forces BQ2 to conduct allowing the
support voltage VBAT to illuminate the backlights.
104. The keypad is made up of a 4 column x 5 Row matrix, with the signals ROW4 –
ROW 0 being generated from Gemini Pins 126 to Pins 122 respectively. The column
signals, COL3 Gemini Pin 129, COL2 Pin 128, COL1 Pin 133 & COL0 Pin 132.
105. The 2 signals ROW4 and COL4 are used as outputs from the Gemini to Keypad
detect switch U34 to inform the unit to switch on during sleep mode.
