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 ~ 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 interferers. 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 8dB gain steps in front of the filters.
2) TX PART
Baseband 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 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).
Backlight Brightness Modulator
1.2.
The Backlight Brightness Modulator (BBM) contains a programmable Pulse-width
to modulate the intensity of a series of LED’s or to control a DC/DC converter that drives LCD backlight.
This phone (SGH-X600) is not use PWM, but use DC CONTROL (COLOR_LCD_BL)
So "COLOR_LCD_BL" voltage is high value, backlight brightness is bright and "COLOR_LCD_BL" voltage is low value,
backlight is gloomy .
Clock Generato
1.3.
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 LCD(color 65K STN LCD). Chip select signals in the U500, LCD_CS can enable LCD. This signal
is from IO part of the DSP in the U500(alpha chip). "RESET_2.8V" 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_WD" signal is
used to write data or commands to LCD. Power signal for LCD is "VDD2".
2-2. 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. It uses two power signals. "VDD2" is used for
circuit and "VBAT" is used for LED.
2-3. 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. Ten key LEDs use the "BLVDD" supply voltage.
"COLOR_LCD_BL" signal enables LEDs with current control.
2-4. EMI ESD Filter
This system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part.
2-5 IF connetor
It 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
EARP_P and EARP_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.
YMU762C 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, YMU762C 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.

SGH-X600 Circuit Description
Since the play data of YMU762C 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.
YMU762C 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 and a circuit for controlling LEDs
synchronous with music.
For the headphone, it is provided with a stereophonic output terminal.
For the purpose of enabling YMU762C 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 YMU762C directly interprets and plays blocks relevant
to synthesis (playing music and reproducing ADPCM with FM synthesizer) that are included in data distributed in SMAF.
5. Memory
signals in the OM6357 enable two memories. They use only one volt supply voltage, VDD3 in the PCF50601. This
