VC-TCXO (U102) This module generates the 26MHz reference clock to drive the logic and RF. It is turned on when the supply voltage +VCC_SYN is applied. After buffering a reference clock of 26MHz is supplied to the other parts of the system through the transceiver pin OUT. TRANSCEIVER (U100) This chip is fully integrated GSM GPRS tri-band transceiver with VCO, loop filters and most of the passive component in it. And also fully integrated fractional N RF synthesizer with AFC control possibility, RF VCO with integrated supply regulator. Semi integrated reference oscillator with integrated supply regulator. RF Receiver front-end amplifies the E-GSM900, DCS1800 and PCS1900 aerial signal, convert the chosen channel down to a low IF of 100kHz. In IF section, further amplifies the wanted channel output level to the desired value and rejects DC.

2-2-1. PCF50603 (U403)

Power Management Eight 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 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 PCF50603 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 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-E340) use PWM control to contrast the backlight brightness.
Clock Generator The Clock Generator (CG) generates all clocks for internal and external usage. The 32.768 kHz crystal oscillator provides an accurate low clock frequency for the PCF50603 and other circuitry.

2-2-2. LCD Connector

LCD is consisted of main LCD(color 6.5K TFT LCD). Chip select signals in the U304, LCD_CS, can enable LCD. BACKLIGHT signal enables white LED of main LCD. These signal is from U403. 16-bit data lines(LD(0)~LD(15)) transfers data and commands to LCD. 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 "VDD_IO_HIGH".

2-2-3. Key

This is consisted of key interface pins KEY_ROW(0:4) and KEY_COL(0:4) in PCF5212EL1. These signals compose the matrix. Result of matrix informs the key status to key interface in the PCF5212EL1. Power on/off key is seperated from the matrix. So power on/off signal is connected with PCF50603 to enable PCF50603. Key LED is consisted of sixteen blue LEDs. key LED use the 3.3V LDO(U604) for a supply voltage. KEY_LED_ON signal enables sixteen blue LED. "FLIP" informs the status of slide (open or closed) to the PCF5212EL1. This uses the hall effect IC, SH248CSP(U602). A magnet under LCD enables SH248CSP.
2-2-4. EMI ESD Filter(U501)
This system uses the EMI ESD filter, U501 to protect noise from IF CONNECTOR part.
2-2-5. IF connetor(CN302)
It is 18-pin connector. They are designed to use VBAT, V_EXT_CHARGE, USB_D+, +VBUS, USB_D-, TXD1, RXD1, AUX_ON, EXT1, EXT2 and GND. They connected to power supply IC, microprocessor and signal processor IC.
2-2-6. Battery Charge Management IC(U505)
A complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries is used. 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.

2-2-7. Audio

HFR_P and HFR_N from PCF5212EL1 are connected to the main speaker via analog switches. MIC_P and MIC_N are connected to the main MIC as well. EAR1 is the source of External Speaker. YMU762 is a synthesizer LSI for mobile phones. This LSI has a built-in speaker amplifier for outputting sounds that are used by mobile phones in addition to game sounds and ringing melodies that are replayed by a synthesizer. The synthesizer section adopts Table voices. It provides simultaneous generation of up to 40 tones by stereophonic hybrid synthesizer. YMU762 has built a speaker amplifier of which maximum out is 580 mW at SPVDD=3.6V in this device. There is Stereophonic analog output for Headphone. stereophonic hybrid synthesizer system that are given advantages of both FM synthesizers and Wave Table synthesizers to allow simultaneous generation of up to 32 FM voices and 32 Wave
