- GSM FILTER (F100) → 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 (F101) → For filtering the frequency band between 1930 and 1990 MHz.
4. VC-TCXO (U101)
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 CLKOUT.
5. TRANSCEIVER (U102)

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) TX PART
The transmitter is fully differential using a direct up conversion architecture. It consists of a signal side band
power up mixer. Gain is controlled by 6 dB via 3-wire serial bus programing. The fully integrated VCO and power
mixer achieve LO suppression, quadrature phase error, quadrature amplitude balance and low noise floor specification.

Circuit Description
2. Baseband Circuit description of SGH-D500
1. PCF50603 (U400)
1.1. 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).
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-D500) use PWM control to contrast the backlight brightness.
1.3. 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. LCD Connector
LCD is consisted of main LCD(color 26K TFT LCD).
Chip select signals in the U305, LCD_CS, can enable LCD. BACKLIGHT signal enables white LED of main LCD. These
signal is from U400.
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".
3. IRDA
This system uses IRDA module, HSDL_3209, Agilent's. This has signals, "IRDA_EN"(enable signal), "IRDA_RXD"(input
data) and "IRDA_TXD"(output data). These signals are connected to PCF5213EL1 through BT Module.

Circuit Description
4. Key
This is consisted of key interface pins KEY_ROW(0:4) and KEY_COL(0:4) in PCF5213EL1. These signals compose the
matrix. Result of matrix informs the key status to key interface in the PCF5213EL1. 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
six white
LEDs for sub key and twelve white LEDs for main key. White LED for sub key use the VBAT voltage.
"SLIDER_KEY_ON" signal enables Transistor for sub key backlight.
Main key LED use the 3.3V LDO for a supply voltage. KEY_LED_ON signal enables eight white LED.
"FLIP" informs the status of slide (open or closed) to the PCF5213EL1. This uses the hall effect IC, A3212ELH.
A magnet under LCD enables A3212ELH.
5. EMI ESD Filter
This system uses the EMI ESD filter, U500 to protect noise from IF CONNECTOR part.
6. IF connetor
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, HFK_SPK, HFK_MIC and GND. They connected to power supply IC, microprocessor and signal
processor IC.
7. 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.
8. Audio
HFR_P and HFR_N from PCF5213El1 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. YMU765 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 “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
Table voices.
It provides simultaneous generation of up to 64 tones by stereophonic hybrid synthesizer.
YMU765 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.
9. Memory
This system uses Samsung's memory, KBJ10KB00M. The KBJ10KB00M is a Multi Chip Package Memory which
combines 256Mbit Synchronous Burst Multi Bank NOR Flash Memory and two 512Mbit OneNAND Flash and
128Mbit Synchronous Burst U tRAM.
It has 16 bit data line, HD[1~16] which is connected to PCF5213 and MV319, also has 24 bit address lines,
HA[1~24]. There are 3 chip select signals, CS0n_FLASH, CS4n_NAND, and CS1n_RAM.
In the Wrting process, WEn is fallen to low and it enables writing process to operate. During reading process,
OEn is fallen to low and it enables reading process to operate. Each chip select signals in the PCF5213 choose
different memories.
