SGH-D820 RF Circuit Description RX PART - FRONT END MODULE(ANTENNA SWITCH MODULE + RX SAW FILTER) (F101) It performs to switch Tx & Rx paths for GSM850, GSM900, DCS1800 and PCS1900 with logic controls below. - FEM Control Logic Table FESW1 FESW2 FESW2 Tx Mode (GSM850/900) H L L Tx Mode (DCS1800/1900) L H L Rx Mode (GSM900/850) L L L Rx Mode (DCS1800) L L L Rx Mode (PCS1900) L L H - VC-TCXO (TCX100) This module generates the 26MHz reference clock to drive the logic and RF systems. It is turned on when the supply voltage (+VCC_SYN) is applied. After buffering, the 26MHz reference clock is supplied to the other parts of the system through the transceiver pin CLKOUT. - Transceiver (U102) This chip is fully integrated GSM & GPRS quad-band transceiver with RF VCO, loop filters and most of the passive components required in it. It also fully integrated fractional N RF synthesizer with AFC control possibility, RF VCO with integrated supply regulator. Semi integrated reference oscillator with integrated supply regulator. RF Receiver front-end amplifies the E-GSM900(GSM850), DCS1800 and PCS1900 aerial signal, convert the chosen channel down to a low IF of 100kHz. In IF section, further amplifies the wanted channel, performs gain control to tune the output level to the desired value and rejects DC TX PART The transmitter is fully differential using a direct up conversion architecture. It consists of a signal side band power up mixer. Gain is controlled by 6 db via 3-wire serial bus programing. The fully integrated VCO and power mixer achieve LO suppression, quadrature phase error, quadrature amplitude balance and low noise floor specification. Output matching/balun components drive a standard 50 ohms single ended load. 2-1

6 Circuit Description 2-2. Baseband Circuit description of SGH-D PCF50603 (U400) - Power Management Eight low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal system performance and long battery life. A programmable boost converter provides support for 1.8V, 3.0V SIMs, while a self-resetting, electronically fused switch supplies power to external accessories. Ancillary support functions, such as RTC module and High Voltage Charge pump, Clock generator, aid in reducing both board area and system complexity. I2C BUS serial interface provides access to control and configuration registers. This interface gives a microprocessor full control of the PCF50603 and enables system designers to maximize both standby and talk times. Supervisory functions. including a reset generator, an input voltage monitor, and a temperature sensor, support reliable system design. These functions work together to ensure proper system behavior during start-up or in the event of a fault condition(low microprocessor voltage, insufficient battery energy, or excessive die temperature). - Pulse-Width Modulator The Backlight Brightness Modulator (BBM) contains a programmable Pulse-width modulator (PWM) to modulate the intensity of a series of LED's or to control a DC/DC converter that drives LCD backlight. This phone is using PWM control to modulate the LCD backlight brightness. - Clock Generator The Clock Generator (CG) generates all clocks for internal and external usage. The khz crystal oscillator provides an accurate low clock frequency for the PCF50603 and other circuitry LCD D820 has just one 2.12" TFT LCD. 16-bit data lines(ld(0)~ld(15)) transfers data and commands to LCD. There are couple of control signals such as RS, LCD_MAIN_CS, L_WRB, etc. RS stands for "Register Select pin." When RS = 0, data can be written to the index register or status can be read, and when RS = 1, an instruction can be issued or data can be written to or read from RAM. Read or write operation is selected according to L_WRB signals. The data is received when the R/W bit is 0, and is transmitted when the R/W bit is 1. At the falling edge of LCD_MAIN_CS input, serial data transfer is initiated. On the other hand, at the rising edge of LCD_MAIN_CS input, the data transfer is ceased Key Key recognition part is consisted of 8 ports from PCF5213EL1. KEY_ROW(0:4) & KEY_COL(0:4) These signals performs with the matrix. Any input from the matrix informs the key status to key interface in the PCF5213EL1. Power on/off key is independent of the matrix. Therefore, 'power on/off' signal is directly connected with PCF50603 to turn PCF50603 on. Two 3.3V LDOs(U716, U823) enable Main and Sub Key LED on. Main and Sub Key LED are controlled by KEYLED_ON and SLIDER_KEY_ON signal respectively. 2-2

7 Circuit Description EMI ESD Filter (F500) This system uses the EMI ESD filter (F500) to protect the device from noises from IF CONNECTOR part IF connetor (IFC500) It has 20-pin.

They connected to power supply IC, microprocessor, signal processor IC and Earphone Battery Charge Management D820 has a complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries inside. If Travel Adapter is connected, "V_EXT_CHARGE" begins to provide the charger IC (to battery) with power (current). When the charging operation is done, "END_OF_CHG" informs it to PCF5213EL1 to stop the operation. "CHG_ON" signal enables the charger IC to operate in adequate circumstances Audio - Part D820 has several audio-outputs such as stereo speaker, receiver, earphone, etc. HFR P/N signals from CPU are connected to the receiver. MIC_CP/N are connected to the main MIC and MIC_CP2/N2 as well. SAPA1D2 is a Class-D amplifier for outputting sounds that are used by mobile phones including MP3 playback, melodies, voice output on speaker phone mode and so on.. STG3699(U515) is an analog switch to connect SAPA1D2 input port to main DSP or CODEC Chip Memory (UME307) D820 has KBH10PD00M-D414 as a memory module.
