SGH-E700 Circuit Description 200kHz offset 30 kHz bandwidth Modulation Spectrum 400kHz offset 30 kHz bandwidth 600kHz ~ 1.8MHz offset 30 kHz bandwidth GSM -35dBc DCS -35dBc PCS -35dBc GSM -66dBc DCS -65dBc PCS -66dBc GSM -75dBc DCS -68dBc PCS -75dBc 2. Baseband Circuit description of SGH-E700 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.
SGH-E700 Circuit Description "RESET_2V8" signal initiates the Reset process of the LCD. 16-bit data lines(LD(0)~LD(15)) transfers data and commands to LCD through by pass 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 input or output state to LCD, is required. But this system is not necessary this signal. So "L_WR" signal is used to write data or commands to LCD.
SGH-E700 Circuit Description The hardware sequencer built in this device allows playing of the complex music without giving excessive load to the CPU of the portable telephones. 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.
SGH-E700 Circuit Description 7. TCO-9141D(13MHz) This system uses the 13MHz TCXO, TCO-9141D, Toyocom. AFC control signal form OM6357 controls frequency from 13MHz x-tal. It generates the clock frequency. This clock is connected to OM6357, YMU762 and OM5178. 9.Camera DSP(MV317SA) Tiger is an Integrated circuit for mobile phone camera. This structure will allow effectiveness for large data management and significantly reduces main processor will get burden.
