RX PART - ANTENNA SWITCH (Module1 Front End Module) → Switching Tx, Rx path for GSM900, DCS1800 and PCS1900 by logic controlling. - ANTENNA SWITCH Control Losic (Module1) → Truth Table VC1 VC2 VC3 Tx Mode (GSM900) H L L Tx Mode (DCS1800/1900) L H L(H) Rx Mode (GSM900) L L L Rx Mode (DCS1800) L L L Rx Mode (PCS1900) L L H - VC-TCXO (U102) This module generates the 26MHz reference clock to drive the logic and RF.
Circuit Description 2-2. Baseband Circuit description of SGH-E730 2-2-1. PCF50603 (U400) - Power Management Eight low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal system performance and long battery life. A programmable boost converter provides support for 1.8V, 3.0V SIMs, while a self-resetting, electronically fused switch supplies power to external accessories.
Circuit Description 2-2-5. EMI ESD Filter This system uses the EMI ESD filter, U500 to protect noise from IF CONNECTOR part. 2-2-6. IF connetor It is 18-pin connector. They are designed to use VBAT, V_EXT_CHARGE, USB_D+, +VBUS, USB_D-, TXD1, RXD1, AUX_ON, EXT1, EXT2, and GND. They connected to power supply IC, microprocessor and signal processor IC. 2-2-7. Battery Charge Management A complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries.
Circuit Description HD(0:15), data lines and HA(0:23), address lines are connected to KBJ10KB00M (memory), MV3315DOQ (image dsp) and YMU765 (melody IC). It has 64 kbyte SC RAM (0.5 Mbit) and 32 kbyte SC program ROM for bootstrap loader in the ARM core. HD(0:15), data lines and HA(0:23), address lines are connected to memory and YMU765 to communicate. MV3315DOQ(Camera DSP Chip) controls the communication between ARM core and DSP core. OEn, WEn control the access of memory.
