3. FILTER

To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band.

- GSM FILTER (F101) → For filtering the frequency band between 925 ~ 960 MHz

- DCS FILTER (F102) → 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 U103 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. Transceiver (U103)

The receiver front-end converts the aerial RF signal from EGSM, DCS bands down to a low intermediate frequency (IF)

of 100 kHz. The first stages are symmetrical low noise amplifiers (LNAs). They are matched to 50 ohm. The LNAs are

followed by an I, Q down-mixer. It consists of two mixers in parallel but driven by quadrature out of phase LO signals.

The In phase (I) and Quadrature phase (Q) IF signals are low pass filtered to provide protection from high frequency

offset interferes. The low IF I and Q signals are then fed into the channel filter. The front-end low IF I and Q outputs

enter the integrated bandpass channel filter with provision for five 8 dB gain steps in front of the filter.

2) TX PARTBaseband IQ signal fed into offset PLL, this function is included inside of U103 chip. OSC100 chip generates modulator

signal which power level is about 6.5dBm and fed into Power Amplifier(U101). The PA output power and power ramping

are well controlled by Auto Power Control circuit. We use offset PLL below

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

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. 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 or to control a DC/DC converter that drives LCD backlight. This phone (SGH-X100) is

not use PWM, but use DC CONTROL (BACKLIGHT). So "BACKLIGHT" voltage is high value, backlight is bright.

1.3. Clock GeneratorThe 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 STN LCD). Chip select signals in the U304, LCD_CS can enable LCD.

LCD_CS signal is LCD select signal. This signal is from ENABLE part of OM6357.

"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. 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 signali for LCD is "VDD3".

2-2. 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 seperated from the matrix. So power on/off

signal is connected with PCF50601 to enable PCF50601. Ten key LEDs use the "VDD_KEY" supply voltage.

"VDD_KEY" signal enables LEDs with current control.

2-3. EMI ESD Filter

This system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part.

2-4. IF connetorIt is 18-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. 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,

"V_EXT_CHARGE" 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

REC_P and REC_N from OM6357 are connected to the main receiver. 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.

YMU762MA3 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, 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 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 YMU762MA3 to demonstrate its full capablities, 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 traning karaoke,

and commercial channel that combines texts, images and sounds, and others. The hardware sequencer of YMU762MA3

directly interprets and plays blocks relevant to systhesis (playing music and reproducing ADPCM with FM synthesizer) that

are included in data distributed in SMAF.
