A008 / A6188+ Level 1 & 2 Service Manual Product Overview Features The A008 (E MEA) A6188+ (Asia) is a GSM dual band (900/1800 MHz) GPRS product, and is an enhanced version of A6188. From this point onwards we will refer to this product as the A008. The A008 is mechanically very similar to the existing A6188 form factor with slight modifications made to the flip and front Housing to ensure a different look. The display will be 320 x 240 pixels, 4 level gray scale ¼ VGA display.
A008 / A6188+ Level 1 & 2 Service Manual BCH As can be seen from the above drawing, up to 8 different users can occupy 1 single timeslot at any given time. The more Bandwidth that is required, the more channels are allocated by the network. This extra timeslot allocation is only given when the network is not busy, and therefore dynamically maximises idle network resources. Also because much of the SMS messaging will now be carried over the GPRS system this will relive much of the SMS Centre loading.
A008 / A6188+ Level 1 & 2 Service Manual K-Java K-Java is basically a protocol used to download applications to a device; there are 3 methods of achieving this.

A008 / A6188+ Level 1 & 2 Service Manual WAP Format is derived as follows 1. The request for information is made in WML (Wireless Mark-Up 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.

A008 / A6188 + Level 3 Circuit Description 03 / 03 / 01 V1.
A008 / A6188+ – Circuit Description A6188 Level 3 Product Guide RF: Receive 1) The RF Signal from the base station is received through the Antenna A1 and is fed to RF Switch U101, This connects RF to the Aux RF port or the antenna, and isolates TX from RX. The switch is controlled primarily by the following signals SW_RF: This is a 50Ω load signal from Pin 2 of the Accessory Socket J600, when an external device is attached.
A008 / A6188+ – Circuit Description decrease as the voltage across the PN junction increases. So by varying the reverse voltage across a PN junction the junction capacitance can be varied .This is shown in the typical varactor voltage-capacitance curve below. Fig 6.1. This variable N P Fig 6.1 + capacitence can then be used along with the inductive strip (PCB Tracks lying very close) to provide a LC tuning resonant circuit. The tuning voltage for the varactor is provided by CP_RX (MAGIC U913 Pin A1).
A008 / A6188+ – Circuit Description Different Earthing Points 10) The signal is then passed to the MAGIC IC U200 PRE IN Pin A7 11) The signal is demodulated internally using an external Varactor diode RX Local Oscillator set up CR259, which is driven by LO2 CP Pin A9 of MAGIC U200. 12) Where in earlier products, we used to have RX RXQ, and I these signals are now only used in digital form within the MAGIC and cannot be measured without technical set up.
A008 / A6188+ – Circuit Description this data is already decided for the transmission burst, and therefore a frame synch is not required. 6) The SPI bus signals enters into the MAGIC at Pin G7 (BCLKX) and Pin J2 (BDX) 7) The operation of the MAGIC is very complex and with respect to the transmit path, integrates the functions of the Modem and its function of GMSK (Gaussian Minimum Shift Keying) and also the functions of the TIC (Translational Integrated Circuit).
A008 / A6188+ – Circuit Description 11) The Loop filter comprises mainly of U200 / Q201 / Q202 and C205 and it’s main function is to ‘smooth’ out any overshoots when the channel is changed, see Fig 11.1. If this overshoot were fed to the TX VCO the resulting burst would not meet the world standards for GSM with respect to bandwidth, see Fig 11.2. Overshoot Channel 56 Fig 11.2 Channel 24 Fig 11.
A008 / A6188+ – Circuit Description 18) PA matching is achieved using the MCIC Filter FL300 and the signal GSM_PINDIODE (-5V and DCS_SEL through Q322). The signal switches in or out tuning stubs within the MCIC to provide correct matching. The MCIC filter also samples off part of the transmitted power to feed back to the PAC IC U340 19) The signal now goes through FL1000, FL1000 is a low pass filter, filtering 2nd and 3rd harmonics of GSM and DCS frequencies.
A008 / A6188+ – Circuit Description Fig 6.1 DMCS goes high TX starts TX_KEY goes high SAT_DET goes low Linear ramp down begins SAT_DET goes high Ramp down ceases TX_KEY Goes low DMCS goes low Logic: Power Up sequence 1) The power up sequence is very similar to Kramer with the 2 sources of power being the battery which is a slim version of the Zap battery (SNN5713A), or using an External B+ source. The unit will not operate without the battery.
A008 / A6188+ – Circuit Description controlled through Battery FET Q942 by GCAP II Output Pin F10 and is output as B+ 2) Once B+ is available the unit carries out the following checks: • The battery temperature is monitored to establish whether rapid charge is required, (J610 BATT_THERM_AD to GCAP II Pin B3) -40 deg C – 2.75V 25 deg C – 1.39V 40 deg C – 0.96V • Charger sensed (J600 Pin 5 MANTEST_AD to GCAP II Pin A1) This is achieved using different sense resistors within the accessory.
A008 / A6188+ – Circuit Description As excess current is drawn through B+ towards L901 through Q9808 source, Pin 4. Q902 base will go low forcing its collector high. This high on Pin 3 Gate of Q9808 will switch off Q9808, therefore preventing B+ to the power supply, until LX is stable. • V2 – Programmed to 2.775V, available whenever the radio is on and supplies most of the logic side of the board. V2 is supplied out of GCAP II Pin J2 and can be measured on either C923 or C924. • V3 – Programmed to 2.
A008 / A6188+ – Circuit Description 5) The unit will then follow on as in the sequence below: 0 50 100 150 200 250 300 350 400 450 500 RESET EPROM CE SRAM VB&LB SPI_CE GCAP R/W SPI_CE MAGIC CLK SELECT VCLK BFSR 1.7 after RESET, BCKLR at 1.6s DSC_EN DOWNLINK V1 UPLINK 6) 13 MHz clock. On Power Up there are 2 different reference clocks produced.

A008 / A6188+ – Circuit Description mechanical SIM presence detect switch and to prevent the SIM card being removed whilst connected to Aux Power. NB With no SIM card, Antenna Off can be selected and the unit can be used directly as an organiser without the use of the transceiver. Logic: Charger Circuit 1) The charging operation is as follows: 2) After a charger has been detected MAN_TEST_AD, the Whitecap U700 will communicate with the device via DSC_EN.
A008 / A6188+ – Circuit Description Logic: Keypad Operation 1) The keypad works as a matrix supported by V2. The signals inform the Whitecap upon a key press by dropping the signal ‘low’. There are only 6 ‘hard’ keys, these are: PAGE UP – KBR0 PAGE DOWN – KBR1 HOME – KBC0 POWER – PWR_SW VA – KBC3 JOG DIAL – KBR2 / KBR3 for clockwise operation KBC1 / GND for counter clockwise operation KBR3 / KBR2 for push.
A008 / A6188+ – Circuit Description 3) System Integration Module (SIM28-EZ ) Related to External Array Logic, such as: • System configuration, programmable address mapping • Interface to SRAM, EPROM, FLASH memory • 8 programmable chip selects with wait state generation logic • 4 programmable interrupt I/O and with keyboard interrupt capability • 5 general purpose, programmable edge/level/polarity interrupt IRQ • Other programmable I/O, multiplexed with peripheral functions up to 47 parallel I/O • Low-Power

PENIRQ +Vcc X+ A D C XYY+ Touch Screen 8) The analogue signal is fed from the LCD PCB as RIGHT / TOP / LEFT / BOTTOM on J9805 Pins 1,2, 3 & 4 respectively and is fed to the ADC converter on Pins 2, 3,4& 5. This data is then relayed to and from Dragon Ball on SPM_TXD and SPM_RXD. The ADC is supported by PDA_VCC.
A008 / A6188+ – Circuit Description UPLINK / GCAP UPLINK lines or for example Flash Information can be programmed into either Processor using DOWNLINK / GCAP_DOWNLINK. 4) IrDA – The IrDA transceiver module is U9812. The IrDA data takes the form of an SIP (Serial Infrared Pulse) with SD_IrDA being an active high signal that turns the LED on. The received signal IrDA RXD is always a pulsed, active low 2.4µs pulse, and a low will light the LED.
