Technical Summary of System Part
The RAE-3 system hardware is based on a special version of the DCT3 MAD2
ASIC called MADLinda. MADLinda carries out all the signal processing and operation controlling tasks of the phone as well as all PDA tasks. To be able to run
simultaneously both CMT and PDA applications, MADLinda (ROM1) has a
52MHz ARM9 core.
MADLinda’s main blocks include: ARM925 MPU Subsystem, Traffic Controller
(TC), LEAD2 DSP megamodule (LMM), GSM System Logic and PDA peripherals. ARM925 MPU Subsystem includes ARM9TDMI core, data and instruction
caches, data and instruction memory management units (MMU) and write and
address buffers. Traffic Controller includes primary DMA controller, LCD controller and Flash and SDRAM memory interfaces. The System Logic of MAD2 is
able to support high speed data features (HSCSD). PDA peripherals include
interfaces for Serial Flash, MMC, IrDA, serial port, IOs and PWMs.
In addition of the MADLinda IC the system hardware includes memories, infrared transceiver, COBBA_GJP, CCONT and CHAPS ASICs, audio amplifier
and power regulators. CSP packages are used for all ASICs. System HW also
has connectors for MultiMediaCard (MMC) and SIM card, UI connector and
pads for system connector’s spring contacts.
Technical Documentation
Three XIP Flash devices are used for program code storage. A serial Flash device is used half for the Flash file system and half to save application code. A
synchronous DRAM (SDRAM) device is used as data memory. Code can also
be run from the SDRAM. This is used to run applications loaded from Serial
Flash or MultiMediaCard.
The main battery voltage range in RAE-3 is 3.0V to 4.2V. Battery charging is
controlled in SW using CCONT and CHAPS ASICs. RAE-3 can also supply 3
V(max 100mA) accessory voltage out from system connector.
The system electronics run from a 2.8V power rail. 1.8V is used as core voltage
inside MADLinda and as I/O voltage for XIP Flash memory interface.
Power supplying of the BL8 module, both system HW and RF, and also 2.8V
supplying for the UI module is carried out in system HW. A linear regulator is
used to generate 2.8V VBB voltage and a DC/DC converter is used to generate
the 1.8V Vcore voltage. Accessory voltage and MMC supply are generated with
separate 3V linear regulators. Other supplies are generated using the CCONT
power ASIC (4.7V needed in DCT4 RF is generated in RF side). CCONT generates also the main reset for the system.
Both 3V and 5V Plug–in SIM–cards are supported. SIM is interfaced through
CCONT, which does signal level shifting and generates correct supply voltage
for SIM.
A real time clock function is integrated into CCONT, which utilizes the same
32kHz clock supply as the sleep clock. A rechargeable backup battery provides
backup power to run the RTC when the main battery is removed. The backup
time is about 10 days. Note also the information in section 8 chapter 2.6.

Technical Documentation
The interface from the system part and the RF and audio sections is handled
by a specific ASIC COBBA_GJP. This ASIC provides A/D and D/A conversion
of the in–phase and quadrature receive and transmit signal paths and also A/D
and D/A conversions of received and transmitted audio signals. Data transmission between the COBBA_GJP and the MADLinda is implemented using serial
connections. Digital speech processing is executed by the MADLinda ASIC.
External audio is connected to RAE-3 through system connector’s XMIC and
XEAR lines.
Serial connection channels in RAE-3 include IrDA, MBUS, and serial port.
MBUS and serial port have logic level signals which are connected through system connector. IR transceiver is next to the system connector at the bottom end
of RAE-3 device.

Functional Description
Modes of Operation
There are three main operation modes in the system when power is on:
– Running
– Idle
– Deep Sleep
Note that phone can be either on or off in each of power on states.

Power OFF
IdleRunningDeep Sleep
(VCXO ON)(VCXO ON)(VCXO OFF)
Figure 3. Basic Operation Modes of RAE-3 (simplified scheme)
Power saving modes are entered under SW control. Returning to running mode
is activated by interrupt (generated internally by MADLinda or from CCONT).
Clocking Scheme
The 26MHz main clock frequency is generated by the VCTCXO located in the
RF section. This clock is divide in HAGAR to 13MHz. Clock signal is buffered
to low level sine wave clock signal (RFC) and fed to system HW side. There it
is connected to MADLinda clock input. The MPU within MADLinda can stop the
clock by shutting off the VCTCXO’s supply voltage (VXO) via CCONT.

The CCONT provides a 32kHz sleep clock generated from 32.768kHz quartz
crystal. This clock signal is used internally in CCONT to run the RTC and
routed to MADLinda (SLEEPCLK). Sleep clock is used to run MADLinda when
the main clock is shut down. A backup battery keeps the RTC running if the
main battery is disconnected.

3. RF+System Module BL8
Other clock signals are generated inside MADLinda using PLLs and clock dividers which are controlled by SW. The maximum clock frequency in the MPU side
is 52MHz and in the DSP side 78MHz.
NO TAG shows the System HW clocking scheme.
Power Control and Reset
In normal operation the system HW is powered from the main battery. An external charger can recharge the battery while also supplying power to RAE-3. The
supplied charger is so called performance charger (ACP–9), which can deliver
850mA.
The power management circuitry provides protection against over–voltages,
charger failures and pirate chargers etc. that would otherwise cause damage to
RAE-3.
Following chapters give an overview about power management issues.
Technical Documentation
Power Distribution
Figure 4 shows the power distribution of RAE-3.
Power supply components – CCONT, VBB, Vcore, VACC and VMMC regula-
tors – and the audio amplifier are powered with main battery voltage. Main battery voltage is also fed to RF part for RF power amplifier (PA) and to the UI
module for backlight and LCD supply.
Separate linear regulator generates the 2.8V VBB power supply. VBB powers
most of the system HW portions including MADLinda, memories, COBBA_GJP’s digital supply and the logic parts of the IR transceiver. It also supplies 2.8V to the UI module.
Separate DC/DC regulator generates the 1.8V Vcore voltage. Vcore is used as
supply for the MADLinda core and as IO voltage for XIP memories.
CCONT’s V2V output is used as enable for VBB and Vcore regulators.
VSIM regulator of CCONT is used to generate either 3V or 5V supplies for SIM
card. This is required so that RAE-3 can support both 3V and 5V SIM cards.
VR6 generates the voltage for COBBA_GJP’s analogue part.
CCONT generates the reference voltage VREF for COBBA_GJP and HAGAR.
It also generates the 5V supply voltage (V5V) for RF. In RF side there is separate regulator that drops this voltage to 4.7V for DCT4 RF use.
Regulators VR1 to VR5 inside CCONT generate voltages for RF HW. Regulator
control signals come from MADLinda.
Separate 3V linear regulator is used to power the MMC card.
Another 3V linear regulator is used to generate accessory power that can be
fed through system connector for external accessory.

Power up
When main battery is connected to device, powering on circuitry keeps CCONT
PWRONX/WDDISX pin connected to ground through10kW resistor as long as
CCONT releases the PURX reset signal. This activates the CCONT immediately when battery is connected.
When the CCONT is activated, it switches on internal baseband and core regulators and generates a power up reset signal PURX for MADLinda. External
Vcore and VBB regulators are powered up, Vcore slightly before VBB.
After 62ms CCONT releases the PURX reset signal. When the PURX is released, MADLinda releases the system reset (ExtSysResetX), the Flash reset
(FLRPX) and internal reset signals and starts the boot program execution. Note
that from battery plug in to PURX release it takes about 100ms since there is
no power in CCONT.
The GenSDIO pin is connected low with pull–down resistor so that booting
starts from MADLinda’s internal boot ROM. If booting is successful (and the
programming device is not connected) the program execution continues from
external program memory.
Technical Documentation
The CMT power switch (on the cover) is read as a normal keyboard input. It is
not connected to CCONT. CMT Power switch only turns the phone functionality
on or off (SW implementation).
Power Off
RAE-3 electronics is powered off only if the main battery voltage drops below
the power off SW limit. This happens when the main battery discharges or is
removed. When battery voltage drops below SW limit, CCONT is powered
down by letting CCONT’s watch dog to go off.
Early warning of battery removal is generated by the battery removal switch.
Switch connects MADLinda’s MPUGenIO6 to ground when user presses the
locking latch of the battery.
Only phone functionality is ”powered off” when the CMT power switch is
pressed. If the main battery is removed when the CMT is on, the SIMIF in
MADLinda powers down the SIM.
Charging
Charging of main battery can be started in any operating mode. The battery
type and capacity are identified by MADLinda by measuring a pull–down resistor connected to BSI contact inside the battery pack. Charging software running
in MADLinda’s MPU measures the battery voltage, size, current and temperature.
In Standard charger concept (2–wire charger) the power management circuitry
controls the charging current delivered from the charger to the main battery.
The charging–current switch inside CHAPS is controlled with 1Hz PWM signal,

issue 1 06/01
Page 29
PAMS
RAE-3
Technical Documentation
generated by CCONT. Note that Standard charger is not sold with RAE-3, but it
is accepted.
In performance charging concept (3–wire charger) a 32Hz PWM signal is fed to
the charger (CHRG_CTRL in system connector). This high rate keeps the
charging–current switch in CHAPS continuously connected.
The PWM pulse width is controlled by the MPU in MADLinda which sends a
control value to CCONT through a serial control data bus. The main battery
voltage rise is limited to a specified level by turning the switch off. Lower limit
(4.8V) in CHAPS is permanently selected because only lithium batteries are
supported. Charging current is monitored by measuring the voltage drop across
a sensor resistor.

Serial connections
Serial interface signals are MBUS (DCE_DCD) [MBUS], DCE_RX [AccTxData],
DCE_TX [AccRxData] and DCE_DTR [DTR]. First name is the contact name in
the system connector and in square brackets is given the signal name used in
schematics. Note that all these signals are logic level signals thus interface
buffering/level sifting according some serial interface standards is done outside
RAE–3.
MBUS is normally connected to PUP USART. When PUP USART is selected to
be connected to transmit and receive lines (FBUS use) MBUS is not usable as
a serial signal. In synchronous mode MBUS is used as USART’s clock input.
Synchronous mode is used in DCT3 type Flashing.
DTR handshaking input is connected to MPUGenIO0. Accessory power output
(VACC) is also fed through the DCE_DTR pin. Diode V489 prevents cable’s signal output to supply power to BL8, when main battery is not connected, and accessory power regulator to supply 3V directly to MADLinda’s input. Pullup R310
is thus needed to generate the high level state of DCE_DTR input to MPUGenIO0.

External Audio Interface
External audio signals, XMIC and XEAR, come from AUDIO_RFI block (see
p.38 ). An external headset accessory, car kit or loop set can be connected to
the external audio lines. External audio lines are also used to detect different
accessories.

Technical Documentation
Main components in power block are:
– CCONT2M power ASIC (N100)
– CHAPS charging control ASIC (N101)
– Linear regulator (N102) for VBB
– DC/DC switching regulator (V105) for Vcore
– Linear regulator (N103) for MultiMediaCard powering (VMMC)
– Linear regulator (N104) for Accessory power output (VACC)
– FET (V108) for control of regulators N102 and V105
– 32.768kHz crystal oscillator (32k XTAL B100)
– 2.7V reset device (D101), NC7SZ175 D–flip–flop (D102) and fets (V102,
V106) for power on & off control
– 2.0V reset device (D100) for backup disconnection

– 2–pin connector (X102) for backup battery (contacts for positive terminals)
– Battery connector (X100) for main battery
– SIM card connector (X101)
Clocking, powering, charging and reset issues of CCONT and CHAPS are covered in separate chapters .
Backup battery is connected to CCONT’s VBACK input and it is charged from
CHAPS’ VBACK supply. Backup battery’s positive contacts are made so that

Technical Documentation
VBACK from CHAPS is connected to CCONT only when the battery is installed
to the connector X102. Backup battery is located on top of RF shield A501 and
grounded through the shield.
2.0V reset device (D100) disconnects backup battery if it’s voltage drops too
much. This prevents deep discharging which would permanently harm the
backup battery.
3.0V VMMC supply voltage for MultiMediaCard is generated with linear regulator (N103) from filtered battery voltage (VB). Regulator is controlled with the
MMC_PWR signal from MADLinda MPUGenIO5.
Accessory power output (VACC) through the system connector’s DCE_DTR
line is generated with 3.0 volts linear regulator (N104) from filtered battery voltage (VB). Regulator’s feed back resistor are internally disconnected from the
output pin when the regulator is not enabled, so output will not affect DCE_DTR
line’s normal signal usage. VACC regulator is controlled with VACC_CTRL –signal from MADLinda’s MPUGenOut1. .

NAME
The type of the connected main battery is identified from the BSI line’s voltage
level. This voltage is formed by the system HW’s pull–up resistor (100kW) and
battery back’s pull–down resistor. Level is read with CCONT’s BSI A/D input.
CON-
NECTED
SIGNAL
MEASURESADC input range
The BSI contact on the battery connector is also used to detect when the battery is being removed to be able to shut down the operations of the SIM card
before the power is lost. The BSI contact is shorter than the supply power contacts so this contact breaks first when the battery pack is removed, giving some
time for the shut–down operations.
The temperature of the main battery is read from the BTEMP line’s voltage level. This voltage is formed by the system HW’s pull–up resistor (100kW) and battery pack’s NTC resistor. Level is read with CCONT’s BTEMP A/D input.

AUDIO_RFI block
The function of the AUDIO_RFI block is to interface between the digital world of
the System Hardware and the analogue world of the audio and RF stages.
Main components are:
– COBBA_GJP (N200)
– Hands free audio amplifier (N201)
– FET (V200) for amplifier shut down control
– V202 for mic lines’ EMI filtering/ESD protection
COBBA_GJP is a combined AUDIO– and RF–codec for DCT3 generation
phones with serial RF TxIQ & RxIQ data lines and serial control interface.
RFI
COBBA_GJP handles the following RFI functions:
– IF receiving with I/Q separation and A/D conversion (RxI, RxQ)
– I– and Q–transmit and D/A conversion (TxI, TxQ)
– transmit power control (TXC) D/A conversion
– Automatic frequency control (AFC) D/A conversion
Technical Documentation
Audio
Digital communication between COBBA_GJP and MADLinda is handled by
MADLinda’s SerialMFI block which controls both serial RF TxIQ and RxIQ data
transfer and COBBA’s control interface.
RAE–3 includes both normal phone audio and personal handsfree (PHF) audio
functionality. Handsfree mode is implemented by speaker and normal mode by
earpiece. Speaker and earpiece are not located on the BL8 module. Signals for
speaker and earpiece are passed through the UI connector. Only one high sensitivity microphone will be used for both modes. On the BL8 module there are
contacts pads (P200, P201) where microphone is connected with spring contacts.
Analogue to digital conversion (ADC) of RAE-3’s microphone signals and digital
to analogue conversion (DAC) of received audio signals (for speakers) are
done in COBBA_GJP. Input and output signal source selection and gain control
is performed inside the COBBA_GJP according to control messages from
MADLinda. Audio tones are generated and encoded by MADLinda and transmitted to COBBA_GJP for decoding. PCM coded digital audio data is moved
between MADLinda’s DSP and COBBA_GJP through the PCM bus. The audio
functions in COBBA_GJP are controlled through the serial control interface
from MADLinda’s SerialMFI block. DTMF and keypad tones are routed to earpiece, while ringer, wav and handsfree audios are routed to handsfree speaker.
External audio signals, XMIC and XEAR, come from system connector. XMIC is
connected to COBBA_GJP’s MIC1N and MIC3N inputs through DC blocking
capacitors. Reference for XMIC is SGND. XEAR is connected to COBBA_GJP’s HF output through DC blocking capacitors. Reference for XEAR is
GND.

Technical Documentation
Audio amplifier IC (N201) is used to amplify the HF output signal of COBBA_GJP for the personal hands free speaker. Audio amplifier shut down mode
is controlled with MADLinda’s MPUGenOut0 line. Because HF amplifier is powered from battery voltage, controlling of shut down is done through pull–down
fet (V200).
HeadDet and HookDet interrupting inputs in MADLinda are used to detect different audio accessories. EAD A/D input in CCONT is used to detect the removal of accessory during call.

Frequency synthesizer
VCO frequency is locked with PLL into stable frequency source, which is a
VCTCXO–module . The VCTCXO is running at 26 MHz. The residual temperature, drift, Doppler and initial inaccuracy effects are compensated with AFC (
automatic frequency control ) voltage. The AFC locks the VCTCXO into frequency of the base station
PLL is located in HAGAR RF–IC and is controlled via serial bus from MADLinda–IC, which is located in the system block.
LO–signal is generated by SHF VCO module. VCO has double frequency in
DCS1800 and x 4 frequency in E–GSM compared to actual RF channel frequency. LO signal is divided by two or four in HAGAR (depending on system
mode).
Receiver
Receiver is a direct conversion, dualband linear receiver. Received RF–signal
from the antenna is fed via RF–antenna switch to 1st RX dualband SAW filter
and discrete LNAs (low noise amplifier). There are separate LNA branches for
EGSM900 and DCS1800.
Technical Documentation
After the LNA amplified signal ( with low noise level ) is fed to bandpass filter
(2nd RX dualband SAW filter).
These bandpass filtered signals are then balanced with baluns. Differential RX
signal is amplified and mixed directly down to BB frequency in HAGAR. Local
oscillator signal is generated with external VCO. VCO signal is divided by 2
(DCS1800) or by 4 (EGSM900). PLL and dividers are in HAGAR–IC.
From the mixer output to ADC input RX signal is divided into I– and Q– signals.
Accurate phasing is generated in LO dividers. After the mixer DTOS amplifiers
convert the differential signals to single ended.
Next stage in the receiver chain is AGC–amplifier, also integrated into HAGAR.
AGC has digital gain control via serial mode bus from MADLinda IC.
Single ended filtered I/Q–signal is then fed to ADCs in COBBA–IC. Input level
for ADC is 1.4 Vpp max.
Transmitter
Transmitter chain consists of final frequency I/Q–modulator, dual–band power
amplifier and a power control loop.
I– and Q–signals are generated by baseband also in COBBA_GJP ASIC. After
post filtering ( RC–network ) they go into IQ–modulator in HAGAR. After modulator the TX–signal is amplified and buffered. There are separate outputs for
both E–GSM and DCS1800. HAGAR TX output level is +3 dBm minimum at 2.8
V modulator supply voltage.
Next TX signals are converted to single ended by discrete baluns. EGSM and
DCS1800 branches are combined with diplexer.

Technical Documentation
The final amplification is realized with dual–band power amplifier. It has one 50
ohm input and two 50 ohm outputs. PA is able to produce over 3 W (4.5 dBm
input level) in EGSM band and over 1.5 W (6 dBm input level) in DCS1800
band into 50 ohm output .
Power control circuitry consists of discrete power detector (common for EGSM
and DCS1800) and error amplifier in HAGAR. There is a directional coupler
connected between PA output and antenna switch. It is a dualband type and
has input and outputs for both systems. This signal is rectified in a schottky–
diode and it produces a pulsed DC–signal after filtering.
Power control loop in HAGAR has two outputs, one for each band.
AGC strategy
AGC–amplifier is used to maintain the output level of the receiver in a certain
range. AGC has to be set before each received burst. Receiver is switched on
roughly 280 us before the burst begins, DSP measures the received signal level and adjusts the AGC–amplifiers via serial bus from MADLinda.
3. RF+System Module BL8
AFC function
AFC is used to lock the transceiver’s clock to frequency of the base station.
AFC–voltage is generated in COBBA with 11 bit D/A–converter. Settling time
requirement for the RC–network comes from signalling, how often PSW ( pure
sine wave ) slots occur. They are repeated every 10 frames, meaning that there
is PSW in every 46 ms. AFC tracks the base station frequency continously, so
transceiver has a stable frequency, because there are no rapid changes in
VCTCXO–output (changes due to temperature and other effects are relatively
slow).

Antenna
One common antenna resonating on both bands is used. The antenna is located in the cover part. The RF connection between the bl8 module and the antenna is a coaxial cable.
RF connector and antenna switch
There are two antenna connectors in bl8 module. One is the connector for external (car kit) antenna and it has an integrated mechanical switch function.
This connector is integrated with the system connector. The other connector is
used for connecting the coaxial cable which leads to the communicator’s own
antenna.

Synthesizer clocking
Synthesizers are controlled via serial control bus, which consists of SDATA,
SCLK and SENA1 signals. These lines form a synchronous data transfer line.
SDATA is for the data bits, SCLK is 3.25 MHz clock and SENA1 is latch enable,
which stores the data into counters or registers. The signal SENA1 is latch enable also for HAGAR control register, which is used for programming some internal functions in HAGAR, e.g. in band changing. In this case SCLK and SDATA are used the same way as in PLL programming.
