FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band.
Circuit Description 2. Baseband Circuit description of SGH-E330 1. PCF50601 1.1. Power Management Ten 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, and 5.0V SIMs, while a self-resetting, electronically fused switch supplies power to external accessories.
Circuit Description signal is connected with PCF50601 to enable PCF50601. Fifteen key LEDs are use the "VBAT" as supply voltage. "VDD_KEY" signal enables LEDs. "FLIP" informs the status of folder (open or closed) to the OM6359. This uses the hall effect IC, SH248CSP. A magnet under main LCD enables SH248CSP. 4. EMI ESD Filter This system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part. 5. IF connetor It is 18-pin connector.
Circuit Description 8. Memory Signals in the OM6359 enable two memories. They use only one volt supply voltage, VDD3 in the PCF50601. This system uses Samsung's memory, KBB06A500M-T402. It is consisted of 128M bits flash NOR memory and 128M bits flash NAND memory and 64M bits SCRAM. It has 16 bit data line, HD[0~15] which is connected to OM6359 and MV317S. It has 26 bit address lines, HA[1~26]. CS_NAND and NCSRAM signals are chip select.
