Description of Block Diagram
1.b.1
IC 300 One-C (vWS22100).
IC300 includes in one chipset Base Band part, DSP, CPU, A/D, D/A converters, TDMA frame
counters, 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.b.2
IC100 IPD (Rohm BH6070KUT).
IC100 provides the different powers supplies to RFBB board : 2.8VRTC, PSTCXO, 2.8VANA,
2.8VAUD, 2.8VD, 2.8VP, 5VSIM. It actives all L.E.D.s (red,green,LCD & keyboard) and the vibrator
inside the battery. The management of the battery charging is carried out by internal circuit of IC100.
1.b.3
IC600 RF-IC (Hitachi HD155121FEB).
Transceiver IC for E-GSM and DCS Dual Band cellular systems.
1.b.4
IC601 PLLs & VCOs
IC601 includes in one chipset 2 PLL, RF VCO and IF VCO.
1.b.5
Memory system.
IC200 : Flash ROM ( 1 M x 16 Bits ) stores the CPU program code
IC201 : RAM ( 128 k x 16 Bits ) stores data for the CPU work.
IC206 : Serial FLASH ( 2 M x 8 Bits) stores the user's datas and hardware adjustment datas.
