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
Idle Running Deep 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.

Deep Sleep conditions met
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.
issue 1 06/01
Page 3 – 25
Page 26
RAE-3

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,

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.

Resets and Watchdogs
Power–up reset signal, PURX, is the main reset in RAE-3. PURX is generated by CCONT during power–on. The watchdog within CCONT is enabled and must be fed periodically to keep CCONT (and whole device) powered on. PURX –signal is connected to MADLinda’s reset input (PURX).

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.

Charger voltage input line V_IN is connected through 1.5A fuse (F450) to CHAPS (charger control) ASIC’s VCH inputs. Divided (47k/4k7) V_IN voltage level is connected to CCONT’s VCHAR ADC input.
Charger controlling PWM output line, CHRG_CTRL, comes from CCONT’s PWM output (PWM_OUT).
External RF
External RF signal comes from RF section of BL8. RF connector in system con­nector includes switch for external/internal signal routing. When external RF plug is not connected to the system connector, RF signal is connected to coax­ial antenna cable connector (X499).

POWER block

Power block includes following functions: – supply voltage generation for system and RF parts and 2.8V to UI – control of main battery charging – power on and power off controlling and reset generation – RTC and RTC backup control – sleep clock generation – SIM interface – A/D conversions – powering of MultiMediaCard – Accessory power output generation (through System Connector)
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 – ESD protection zener array (V103) for SIM interface – 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.

NECTED
SIGNAL
MEASURES ADC 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.

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.

Regulators
Transceiver includes a multi function power management IC (CCONT), which contains among other functions also 7 pcs of 2.8 V regulators. All regulators can be controlled individually with 2.8 V logic directly or through control register. The regulator IC is located in the system block of the transceiver.
Use of the regulators is illustrated in the power distribution diagram Figure 12. VREF_2 from CCONT IC and RXREF from COBBA IC are used as the refer-
ence voltages for HAGAR RF–IC, VREF_2 (1.5V) for bias reference and RXREF (1.2V) for RX ADC’s reference.
Control signals
This table shows used control signals for different functions and the typical cur­rent consumption (VBATT = 3.7 V). All regulators except VXO are switched on and off using the SYNTPWR control signals. The TX and RX blocks are switched on and off under HAGAR control. These controls are accessed via se­rial interface from MADLinda to HAGAR.

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.

issue 1 06/01

PAMS
RAE-3
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.

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).

Connections

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.
