  • Page 1 V2288 Level 3 Circuit Description 17 / 02 / 99 V1.0...
  • Page 2 V2288 – Circuit Description V2288 Level 3 Product Guide Receive 1) The RF Signal from the base station is received through the Antenna A100 and is fed to J300, which is a purely mechanical switch which is operated when an cable is plugged into the Aux RF socket of the phone.
  • Page 3 V2288 – Circuit Description 11) The RX SPI signal is made up of (Base band Data Receive), BFSR (Base band Frame Synch Receive) and BCLKR (Base band Clock Receive, fed from MAGIC Pins G8, G9 and F7 respectively. 12) The...
  • Page 4 V2288 – Circuit Description 8) A very basic block view of how the transmit path works within the MAGIC is demonstrated in: Fig 8.1 Internal MAGIC Operation Fig 8.1 Look Σ Channel Info Digital Digital representation representation of TX VCO...
  • Page 5 V2288 – Circuit Description 12) The Loop filter basically acts then as a huge capacitor and resistor to give a long CR time for smoothing. It uses a small capacitor and the very high input impedance buffer Op-Amp. During the...
  • Page 6 V2288 – Circuit Description SAT_DET Pin 12. If the feedback signal from the RF detector lags too far behind the AOC signal then this output will go low, indicating that the loop in at or near saturation. This signals the DSP to reduce the...
  • Page 7 V2288 – Circuit Description presence detection of the batteries is decided within the COVIC by comparing the actual battery voltage with the created by the charger (Q960àCR960àQ691). If is higher than the normal operating voltage of the batteries, PWR_ON will go low, powering the phone off.
  • Page 8 V2288 – Circuit Description • VREF – Programmed as i.e. 2.775 and provides a reference voltage for the MAGIC IC, distributed from GCAP II Pin G9 and can be measured on C919. • – Used to drive display and –10V –...
  • Page 9 V2288 – Circuit Description On initial power up, all the backlights (DS500 – DSDS11) will be on they are supported from the signal ALRT_VCC (B+ through Q903) and switched by BKLT_EN (Whitecap Pin K3) through Q907. 9) 13 MHz clock. On Power Up there are 2 different reference clocks produced.
  • Page 10 V2288 – Circuit Description • Reset (Whitecap Pin E9 – RST0) in to GCAP II Pin K7 – LS1_IN_TG1A. This signal is then level shifted to the required voltage and fed out to SIM Contacts J803 Pin 4 from Pin J7 - LS1_OUT_TG1A.
  • Page 11 V2288 – Circuit Description 6) When high CHGR_SW will limit the CLA or EIHF current output to 400mA, when MANTEST_AD the current output is limited to 900mA. The AC charger output a current of approximately 350mA. 7) When the batteries are discharged and we turn the phone on, for the first second, full rate charge is delivered, (this is due to the LX signal for V_BOOST being unstable and therefore creating a power surge).
  • Page 12 RADIO FM Radio: FM IC 1) The FM IC is new to any Motorola product and is incorporated into the V2288 Modulus II (R). It is controlled by the FM data bus, consisting of: • RW_AM_FM: WhiteCap output Pin M2. When low, WhiteCap signal...
  • Page 13 V2288 – Circuit Description 1) The antenna signal FMin is routed from the headset ground line through the antenna matching circuit into the tuned front end on Pin 47 of the U1001. The front end and the FM Oscillator are tuned by the...
