3. FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band. - GSM FILTER (L100,L101,L102) → For filtering the frequency band between 925 ~ 960 MHz. - DCS FILTER (L104,L105,L107) → For filtering the frequency band 1805 and 1880 MHz. - PCS FILTER (L108, C151, C152) → For filtering the frequency band 1930 and 1990 MHz. 4. TC-VCXO (U101) To generate the 26MHz reference clock to drive the logic and RF. After additional process, the reference clock applies to the U100 Rx IQ demodulator and Tx IQ modulator. The oscillator for RX IQ demodulator and Tx modulator are controlled by serial data to select channel and use fast lock mode for GPRS high class operation. 5. UAA3536HN (U100) This chip integrates two differential-input LNAs. The GSM input supports the E-GSM, DCS input supports the DCS1800. The LNA inputs are matched to the 200 ohm differential output SAW filters through eternal LC matching network. Image-reject mixer downconverts the RF signal to a 100 KHz intermediate frequency (IF) with the RFLO from VOL1861 frequency synthesizer. The RFLO frequency is between 1801 ~ 1921 MHz. The Mixer output is amplified with an analog programmable gain amplifier (PGA), which is controlled by AGAIN. The quadrature IF signal is digitized with high resolution A/D converts (ADC).
2) TX PART Baseband IQ signal fed into offset PLL, this function is included inside of U100 chip. UAA3536HN chip generates modulator signal which power level is about 1.5dBm and fed into Power Amplifier(U201). The PA output power and power ramping are well controlled by Auto Power Control circuit. We use offset PLL below table.

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. A programmable boost converter provides support for 1.8V, 3.0V, and 5.0V 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 PCF50601 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). 1.2. LCD Backlight Brightness Controler (MAX1574) The Backlight Brightness is controled by Main chip(OM6357_7) through the MAX1574 charge pump. The MAX1574 charge pump drives three white LED's with regulated constant current for uniform intensity. The MAX1574 uses an external resistor to set the full scale 100% LED current. An enable input (EN-"BACKLIGHT") is used for simple on/off control or can be pulsed repeatedly to set lower LED current in multiple steps down to 5%. Once the desired brightness is set, the MAX1574 maintains constant LED current as long as EN is kept high. If EN is kept low for more than 2ms, the MAX1574 enters shutdown. When the LEDs are enabled by driving EN high, the MAX1574 goes through soft-start, bringing the LED current up to ILED_. Dimming is then done by pulsing EN low (500ns to 500µs pulse width). Each pulse reduces the LED current by 10%, so after one pulse the LED current is 0.9 x ILED. The tenth pulse reduces the current by 5%, so the ILED_ current reduces from 0.1 x ILED_ to 0.05x ILED. The eleventh pulse sets the LED current back to ILED_. 1.3. Clock Generator The Clock Generator (CG) generates all clocks for internal and external usage. The 32768 Hz crystal oscillator provides an accurate low clock frequency for the PCF50601 and other circuitry.

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. 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. Power signals for LCD are "VBAT and "VDD2". "SPK_P" and "SPK_N" from OM6357 are used for audio speaker. And "VDD_VIB" from PCF50601 enables the motor. 2-3. IrDA This system uses IrDA module, HSDL_3208, Agilent's. This has signals, "IrDA_DOWN" (enable signal), "RXD0" (input data) and "TXD0" (output data). These signals are connected to OM6357. A power signals, "VDD2" is used for circuit and LED. 2-4. Key This is consisted of key interface pins among OM6357, KBIO[0~7]. These signals compose the matrix. Result of matrix informs the key status to key interface in the OM6357. Power on/off key is seperated from the matrix. So power on/off signal is connected with PCF50601 to enable PCF50601. Key LED is consisted of
four white LED for sub key and six white LED for main key. Key LED use the "BLVDD"
supply voltage. Main key LED is controlled by the "VDD_KEY" supply voltage. "FLIP" informs the status of folder (open or closed) to the OM6357. This uses the hall effect IC, EM-1681-FT. A magnet under main LCD enables EM-1681-FT. 2-5. EMI ESD Filter This system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part. 2-6. IF connector It is 18-pin connector. They are designed to use VBAT, +DCVOLT, TXD0, RXD0, RTS0, CTS0, JIG_REC, CHARGER_OK, RXD1, TXD1 and GND. They connected to power supply IC, microprocessor and signal processor IC.
3. Battery Charge Management A complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries. If TA connected to phone, "+DCVOLT" enable charger IC and supply current to battery. when fault condition caused, "CHG_ON" signal level change low to high and charger IC stop charging process.
4. Audio EARP_P and EARP_N from OM6357 are connected to the main speaker. AUXSP is connected to the Hands free kit. MIC_P and MIC_N are connected to the main MIC. And AUX_MIC_P and AUX_MIC_N are connected to the Hands free kit. 2-3

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. Since the play data of YMU765MA5 are interpreted at anytime through FIFO, the length of the data(playing period) is not limited, so the device can flexiblysupport application such as incoming call melody music distribution service. 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. YMU765MA5 includes a speaker amplifier with high ripple removal rate whose maximum output is 580mW (SPVDD=3.6V). The device is also equipped with conventional function including a vibartor and a circuit for controlling LEDs synchornous with music. For the headphone, it is provided with a stereophonic output terminal. For the purpose of enabling YMU765MA5 to demonstarte its full capablities, Yamaha purpose to use "SMAF:Synthetic music Mobile Application Format" as a data distribution format that is compatible wiht multimedia. Since the SMAF takes a structure that sets importance on the synchronization between sound and images, various contents can be written into it including incoming call melody with words that can be used for traning karaoke, and commercial channel that combines texts, images and sounds, and others. The hardware sequencer of YMU765MA5 directly interprets and plays blocks relevant to systhesis (playing music and reproducing ADPCM with FM synthesizer) that are included in data distributed in SMAF.
