IC300
One-C (VWS22100).
IC300 includes in one same chipset Base Band part, DSP, CPU, A/D, D/A converters, TDMA
framecounters, a TX GMSK modulator, a TX power ramping circuit, RX filters. IC300 carries out the
management of the battery charging, and of the audio part. It interfaces with the radio frequency
part.
1.2.2
IC100
IPD (Rohm BH6070KU).
IC100 provides the different powers supplies to RFBB board : 2.8RTC, PSTCXO, 2.8VANA, PSSYN,
2.8VAUD, VBAT, 3.6VB, 2.8VD, 5VSIM. The management of the battery charging is carried out by
internal circuit of IC100.

System Clock.
The system clock for the telephone is 13 MHz TCXO, generated by X600. It is processed in IC300 to
provide serial clock for LCD, EEPROM, and IC100. The clock is buffered in IC300 One-C, and then
fed to IC100 IPD as " CPU CLK " . It is available on pin 56 of IC100.
During Stand-By mode, the system clock is not managed from X600 TCXO but from X300 ( " slow
clock " at 32.768 kHz).
