2. SGH-P100 Circuit Description 1. SGH-P100 RF Circuit Description 1) RX PART 1. ASM(U1001) → Switching Tx, Rx path for GSM900, DCS1800 and PCS1900 by logic controlling. 2. ASM Control Logic (U701, U702, U703) → Truth Table VC1 VC2 VC3 GSM Tx Mode H L L DCS / PCS Tx Mode L H L PCS Rx Mode L L H GSM / DCS Rx Mode L L L 3. FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band.
SGH-P100 Circuit Description 2) TX PART Baseband IQ signal fed into offset PLL, this function is included inside of U900 chip. SI4205 chip generates modulator signal which power level is about 1.5dBm and fed into Power Amplifier(U1000). The PA output power and power ramping are well controlled by Auto Power Control circuit. We use offset PLL below 200kHz offset 30 kHz bandwidth 400kHz offset 30 kHz bandwidth Modulation Spectrum 600kHz ~ 1.
SGH-P100 Circuit Description 1.4. Vibrator Motor Dirver The vibrator motor driver is a low-side, programmable voltage source designed to drive a small dc motor that silently alerts the user of an incoming call. The driver is enabled by EN_VIB, and its voltage setting is determined by VIB[0:2]. Provided EN_VIB is a logic 1, the driver can be programmed to maintain a motor voltage of 1.1V to 2.5V in 20mV steps and while sinking up to 100mA.
SGH-P100 Circuit Description 3. IF connetor It is 24-pin connector, and uses 18-pin at present. They are designed to use SDS, DEBUG, DLC-DETECT, JIG_ON, VEXT, VTEST, VF, CF, VBAT and GND. They connected to power supply IC, microprocessor and signal processor IC. 4. Audio AOUTAP from CSP1093 is connected to the main speaker. AOUTAN is connected to the speaker via audio-amp. AOUTBN and AOUTBP are connected to the ear-mic speaker via ear-jack. MICIN and MICOUT are connected to the main MIC.
SGH-P100 Circuit Description 6. Trident Trident is consisted of ARM core and DSP core. It has 20K*16bits RAM 144K*16bits ROM in the DSP. It has 4K*32bits ROM and 2K*32bits RAM in the ARM core. DSP is consisted of timer, one bit input/output unit(BIO), JTAG, EMI and HDS(Hardware Development System).
SGH-P100 Circuit Description 9.Camera DSP(LC99704B) - This chipset is MCP product that combines the CCD Driver with on-chip booster circuit and analogue/digital mixed-signal processing IC. The booster circuit generate the supply voltages required for CCD drive. Cameras can use either a +2.8V or +3.0V or +3.3V only power supply system.
