2. SGH-E630 Circuit Description 1. SGH-E630 RF Circuit Description 1) RX PART 1. FEM(U205) → Switching Tx, Rx path for GSM900, DCS1800 and PCS1900 by logic controlling. 2. ASM Control Logic (U100, U207) → Truth Table VC_1 VC_2 VC_3 GSM/DCS Rx Mode L L L PCS Rx Mode L L H GSM Tx Mode H L L DCS/PCS Tx Mode L H L 3. FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band.
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-E630 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.
Circuit Description 2. Connector 2-1. LCD Connector LCD is consisted of main LCD(color 65K TFT LCD). Chip select signals in the U400, LCD_MAIN_CS, can enable LCD. BACKLIGHT signal enables white LED of main LCD. This signal is from IO part of the DSP in the U300(Main Chip). "LCD_RESET" 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.
Circuit Description YMU765MA5 is a LSI for portable telephone that is capable of playing high quality music by utilizing FM synthesizer and ADPCM decorder that are included in this device. As a synthesis, YMU765MA5 is equipped 32 FM voices and 32 Wave Table voices. Since the device is capable of simultaneously generating up to synchronous with the play of the FM synthesizer, various sampled voices can be used as sound effects.
Circuit Description CS_NAND, NCSRAM, NCSFLASH in the ARM core are connected to each memory. HWR_N and HRD_N control the process of memory. External IRQ(Interrupt ReQuest) signals from each units, such as, PMU need the compatible process. KBIO[0~7] receive the status from key and RXD0/TXD0/irDA_DOWN are used for the communicatios using IRDA and data link cable(DEBUG_DTR/RTS/TXD/RXD/CTS/DSR). It has JTAG control pins(TDI/TDO/TCK) for ARM core and DSP core.
