4. TC-VCXO (OSC100)
To generate the 13MHz reference clock to drive the logic and RF.
After additional process, the reference clock applies to the U101 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. OM5178 (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.
OM5178 chip generates modulator signal which power level is about 1.5dBm and fed into Power Amplifier(PAM100).

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. 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-E700) is not use PWM, but use DC CONTROL (BL_VDD)
So "BL_VDD" voltage is high value, backlight brigtness is gloomy and "BL_VDD" voltage is low value, backlight is
bright.
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) and small LCD(256 EL LCD). Chip select signals in the U302,
LCD_MAIN_CS and LCD_SUB_CS, can enable Each LCD. LCD_MAIN_CS signal enables white LED of main LCD and
LCD_SUB_CS signal enables EL of small LCD. These two signals are from IO part of the DSP in the U302(alpha chip).

"RESET_2V8" 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. It uses two power signals. "VDD2" is used for
circuit and "VBAT" is used for 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. 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.
2-5. EMI ESD Filter
This system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part.
2-6 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 Managementa 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. AudioEARP_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.
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 differenttones. 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 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.
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 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 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.
5. Memorysignals in the OM6357 enable two memories. They use only one volt supply voltage, VDD3 in the PCF50601. This

HWR_N is low and it enables writing process to flash memory and SRAM. During reading process, HRD_N is low and
it enables reading process to flash memory and SRAM. Each chip select signals in the OM6357 select memory among 2
flash memory and UtRAM. Reading or writing procedure is processed after HWR_N or HRD_N is enabled. Memories use
reset, which is VDD3 delay from PCF50601. HA[22] signal enables lower byte of SRAM and HA[22] signal enables
higher byte of SRAM.
