2. Circuit Description 2-1. SGH-E330N RF Circuit Description 2-1-1. RX PART - ASM(U103) → Switching Tx, Rx path for GSM900, DCS1800, PCS1900 by logic controlling. - ASM Control Logic (U103) → Truth Table VC1 VC2 VC3 GSM Tx Mode H L L DCS Tx Mode L H L PCS Tx Mode H L L GSM Rx Mode L L L DCS Rx Mode L L L PCS Rx Mode L L H - FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band.
Circuit Description The modulator is loaded at its IF output by an integrated low pass filter that suppress unwanted spurs prior to get into the phase detector. The clock drive is generated by division of the RFLO signal provided for the transmit offset mixer. Baseband IQ signal fed into offset PLL, this function is included inside of U100 chip. OSC101 chip generates modulator signal which power level is about 6.5dBm and fed into Power Amplifier(U102).
Circuit Description 16-bit data lines(LD(0)~LD(15)) transfers data and commands to LCD through bypass capacitor. Data and commands use "RS" signal. If this signal is high, inputs to LCD are commands. If it is low, inputs to LCD are data. The signal which informs the state of LCD is whether input or output, is required. But in this system, there is no input state from LCD. So only "L_WR" signal is used to indicate write data or command to LCD. Power signals for LCD are "VBAT and "VDD2".
Circuit Description Moreover, the registers of the FM synthesizer can be operated directly for real time sound generation, allowing, for example, utilization of various sound effects when using the game software installed in the portable telephone. YMU762C includes a speaker amplifier with high ripple removal rate whose maximum output is 550mW (SPVDD=3.6V). The device is also equipped with conventional function including a vibrator and a circuit for controlling LEDs synchronous with music.
Circuit Description 2-2-10. TOH2600DGI4KRA(26MHz) This system uses the 26MHz TCXO, TOH2600DGI4KRA, SEM. AFC control signal from OM6359 controls frequency from 26MHz x-tal. The clock output frequency of UAA3536 is 13MHz. This clock is connected to OM6359, YMU762C. 2-2-11. Camera DSP(MV3018SAQ) MV3018 is a Camera Control Processor providing the most efficient camera functions for portable terminal devices such as mobile handsets.
