- 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 and 960 MHz

- DCS FILTER (F102) → For filtering the frequency band between 1805 and 1880 MHz.

- PCS FILTER (F100) → For filtering the frequency band between 1930 and 1990 MHz.

- VC-TCXO (OSC101)

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 to 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 (U101)

The receiver front-end which amplifies the GSM, DCS, PCS 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

2-2


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 U101 chip. OSC100 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, 3.0VSIMs, 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 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-X490) use PWM control to contrast the backlight brightness.

- 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.


Circuit Description

2-2-2. LCD ConnectorLCD is consisted of main LCD(color 65K UFB LCD) and sub LCD (B/W LCD).

Chip select signals LCD_MAIN_CS and LCD_SUB_CS, can enable Each LCD. BACKLIGHT signal enables white LED

of main LCD. "LCD_RESET" signal initiates the reset process of the LCD.

16-bit data lines(HD(0)~HD(15)) transfers data and commands to LCD. Data and commands use "HA(1)" signal. If this

signal is low, inputs to LCD are commands. If it is high, 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 "HA(1)" signal is used to indicate write data or command to LCD. Power signals for LCD are

"VBAT and "VDD3".

"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. KeyThis 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. Twelve key LEDs are use the "VDD_KEY" as supply voltage.

"FLIP" informs the status of folder (open or closed) to the OM6359. This uses the hall effect IC, A321ELH-SAMSUNG.

A magnet under main LCD enables A321ELH-SAMSUNG.

2-2-4. EMI ESD FilterThis system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part.

2-2-5. 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.

2-2-6. Battery Charge ManagementA complete constant-current/constant-voltage linear charger is used for single cell lithium-ion batteries.

If TA connected to phone, "+DCVOLT" 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. AudioEARP_P and EARP_N from OM6359 are connected to the main speaker. MIC_P and MIC_N are connected to the main

MIC. YMU788 is a synthesizer LSI for mobile phones. It is a LSI as an input/output device for sound sources, which is

the mobile phones, such as MP3, AAC, etc, in addition to ringing-melodies.

As a synthesis, YMU788 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 YMU788 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.


Circuit Description

2-4


The hardware sequencer built in this device allows playing of the complex music without giving excessive load to the

CPU of the portable telephones.

For the purpose of enabling YMU788 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 YMU788 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. MemorySignals in the OM6359 enable two memories. They use two volt supply voltage, VDD3 in the PCF50601 & VDD_1.9V

64M bits SRAM. It has 16 bit data line, HD[0~15] which is connected to OM6359. It has 26 bit address lines,

HA[1~26]. NCSFLASH & NCSRAM signals are chip select. Writing process, 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. Reading or writing procedure is processed after HWR_N or HRD_N is enabled.

2-2-9. OM6359OM6359 is consisted of ARM core and DSP core. It has 8x1Kword on-chip program/data RAM, 55 Kwords
