2. SGH-E100 Circuit Description Ⅰ. SGH-E100 RF Circuit Description 1. RX PART 1.1 ASM(MODULE1) → Switching Tx, Rx path for GSM900, DCS1800 by logic controlling. 1.2 ASM Control Logic (U206, U208) → Truth Table VC_1 VC_2 GSM Tx Mode H L DCS Tx Mode L H GSM Rx Mode L L DCS Rx Mode L L 1.3 FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band.
SGH-E100 Circuit Description 2. TX PART Baseband IQ signal fed into offset PLL, this function is included inside of U100 chip. UAA3536 chip generates modulator signal which power level is about 1.5dBm and fed into Power Amplifier(U201). The PA output power and power ramping are well controlled by Auto Power Control circuit. We use offset PLL below table. Modulation Spectrum 200kHz offset 30 kHz bandwidth GSM -35dBc DCS -35dBc 400kHz offset 30 kHz bandwidth GSM -66dBc DCS -65dBc 600kHz ~ 1.
SGH-E100 Circuit Description 1.3 Clock Generator The Clock Generator (CG) generates all clocks for internal and external usage. The 32768 Hz crystal oscillator provides an accurate low clock frequency for the PCF50601 and other circuitry. 2. LCD Connector LCD is consisted of main LCD(color 65K TFT LCD) and small LCD(B/W). Chip select signals, LCD_MAIN_CS and LCD_SUB_CS, can enable Each LCD. LCD_MAIN_CS signal enables white LED of main LCD and LCD_SUB_CS signal enables the small LCD.
SGH-E100 Circuit Description when fault condition caused, "CHG_ON" signal level change low to high and charger IC stop charging process. 8. Audio EARP_P and EARP_N from OM6357 are connected to the main speaker. AUXSP is connected to the Hands free kit. MIC_P and MIC_N are connected to the main MIC. And AUX_MIC_P and AUX_MIC_N are connected to the Hands free kit.
SGH-E100 Circuit Description has 16 bit data line, HD[0~15] which is connected to OM6357. It has 23 bit address lines, HA[1~23]. NCSFLASH_NAND and NCSRAM signals is chip select. Writing process, HWR_N is low and it enables writing process to flash memory and SRAM. During reading process, HRD_N is low and it enables reading process to flash memory and SRAM. Each chip select signals in the OM6357 select memory among 2 flash memory and UtRAM.
