- VC-TCXO (OSC100)
This module generates the 26MHz reference clock to drive the logic and RF. After division by two a reference clock of
13MHz is supplied to the other parts of the system through the pin CLKOUT. After additional process, the reference
clock applies t o the U100 Rx IQ demodulator and Tx IQ modulator. And then, the oscillator is controlled by serial data
to select channel and use fast lock mode for GPRS high class operation.

- Transceiver (U100)
The receiver front-end which amplifies the GSM, DCS aerial signal, converts the chosen channel down to a low IF signal
of 100 kHz. The first stages are symmetrical low noise amplifiers (LNAs). The LNAs are followed by an IQ 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.
2-1-2. TX PART
I and Q baseband signals are applied to the IQ modulator that shifts the modulation spectrum up to the transmit IF. It is
designed for low harmonic distortion, low carrier leakage and high image rejection to keep the phase error as small as
possible.

Circuit Description
The modulator is loaded at its IF output by an integrated low pass filter that suppress unwanted spurs prior to get into
the phase detector. The clock drive is generated by division of the RFLO signal provided for the transmit offset mixer.
Baseband IQ signal fed into offset PLL, this function is included inside of U100 chip. OSC101 chip generates modulator
signal which power level is about 6.5dBm and fed into Power Amplifier(U102). The PA output power and power ramping
are well controlled by Auto Power Control circuit. We use offset PLL below table.

2-2-1. PCF50601
- 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
-
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.
But, this phone (SGH-E330N) is use UFB LCD. UFB LCD controls backlight brightness by contrast setting.
So "BL_VDD" voltage is always high value when phone is in active mode. When phone is in dimming mode "BL_VDD"
goes to about 10% duty PWM.
Clock Generato
-
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.

Circuit Description
16-bit data lines(LD(0)~LD(15)) transfers data and commands to LCD through bypass 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 state of LCD is whether input or output, is required. But in this system, there is no input
state from LCD. So only "L_WR" signal is used to indicate write data or command to LCD. Power signals for LCD are
"VBAT and "VDD2".
"M_SCL", "M_SCA", "PCLK", "FVALID", "LVALID" and "STANDBY" signals are all related to camera working.
"CAMERA_FLASH_SUPPLY" is voltage supply to flash led , and "SVC_LED" is signal for service led when the signal
is low led is on and vice versa. "SPK_P" and "SPK_N" are used for audio speaker containing voice or melody. And
"VDD_VIB" from PCF50601 enables the motor.
2-2-3. Key
This is consisted of key interface pins among OM6359, KBIO(0:7). These signals compose the matrix. Result of matrix
informs the key status to key interface in the OM6359. Power on/off key is separated from the matrix. So power on/off
signal is connected with PCF50601 to enable PCF50601. Fifteen key LEDs are use the "VBAT" as supply voltage.
"VDD_KEY" signal enables LEDs. "FLIP" informs the status of folder (open or closed) to the OM6359. This uses the
hall effect IC, SH248CSP. A magnet under main LCD enables SH248CSP.
2-2-4. EMI ESD Filter
This system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part.
2-2-5. 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.
2-2-6. Battery Charge Management
A complete constant-current/constant-voltage linear charger is used for single cell lithium-ion batteries.
If TA connected to phone, "V_EXT_CHARGE" enable charger IC and supply curre nt to battery.
When fault condition caused, "CHG_ON" signal level change low to high and charger IC stop charging
process.
2-2-7. Audio
EARP_P and EARP_N from OM6359 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, 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.
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.

Circuit Description
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.
2-2-8. Memory
Signals in the OM6359 enable two memories. They use only one volt supply voltage, VDD3 in the PCF50601. This
