ASM Control Logic → Truth Table VC_1 VC_2 GSM Tx Mode H L DCS Tx Mode L H GSM Rx Mode L L DCS Rx Mode L L 3. FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band. - GSM FILTER (F100) → For filtering the frequency band between 925 ~ 960 MHz - DCS FILTER (F101) → For filtering the frequency band 1805 and 1880 MHz. 4. VC-TCXO (OSC101) 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. UAA3536(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 150 ohm differential output SAW filters through external LC matching network. Image-reject mixer downconverts the RF signal to a 100 KHz intermediate frequency(IF) with the RFLO from OSC100 voltage-controlled oscillator. 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). 2-1 SAMSUNG Proprietary-Contents may change without notice This Document can not be used without Samsung's authorization Circuit Description B.

Baseband Circuit description of SGH-X460 A. PCF50601 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). 2. Backlight Brightness Modulator The Backlight Brightness Modulator (BBM) contains a programmable Pulse-width modulator (PWM) and FET to modulate the intensity of a series of LED’s or to control a DC/DC converter that drives LCD backlight. This phone (SGH-X460) use PWM. 2-2 SAMSUNG Proprietary-Contents may change without notice This Document can not be used without Samsung's authorization Circuit Description 3.

LCD Connector LCD is consisted of main LCD(color 65K UFB LCD) and small LCD(B/W). Chip select signals, LCD_MAIN_CS and LCD_SUB_CS, can enable Each LCD. Backlight signal enables white LED of main LCD and small LCD. "RESET_2V8" signal initiates the Reset process of the LCD. 16-bit data lines(HD(0)~HD(15)) transfers data and commands to LCD through by pass capacitor. "SPK_P" and "SPK_N" from OM6357 are used for audio speaker. And "VDD_VIB" from PCF50601 enables the motor. 2. 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 separated from the matrix. So power on/off signal is connected with PCF50601 to enable PCF50601. twelve key LED use the "VBAT" supply voltage. "VDD_KEY" signal enables LEDs with current control. "FLIP" informs the status of folder (open or closed) to the OM6357. This uses the hall effect IC, A3210ELH. A magnet under main LCD enables A3210ELH. 3. EMI ESD Filter This system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part. 4. IF connetor It is 24-pin connector. They are designed to use VBAT, V_EXT_CHARGE, TXD0, RXD0, RTS0, CTS0, JIG_REC, CHARGER_OK, RXD1, TXD1, AUX_MIC, AUX_SPK and GND.

Battery Charge Management A complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries. If TA connected to phone, "CHARGER_OK" 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. D. 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. YMU762C is a LSI for portable telephone that is capable of playing high quality music by utilizing FM synthesizer and ADPCM decoder that are included in this device. As a synthesis, YMU762MA3 is equipped 32 voices with different tones. 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 YMU762MA3 are interpreted at anytime through FIFO, the length of the data(playing period) is not limited, so the device can flexibly support 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. YMU762 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 synchronous with music. For the headphone, it is provided with a stereophonic output terminal. For the purpose of enabling YMU762MA3 to demonstrate its full capabilities, Yamaha purpose to use "SMAF:Synthetic music Mobile Application Format" as a data distribution format that is compatible with 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 training karaoke, and commercial channel that combines texts, images and sounds, and others. The hardware sequencer of YMU762MA3 directly interprets and plays blocks relevant to synthesis (playing music and reproducing ADPCM with FM synthesizer) that are included in data distributed in SMAF. 2-4 SAMSUNG Proprietary-Contents may change without notice This Document can not be used without Samsung's authorization Circuit Description E.
