- DCS FILTER (C919,L907) → For filtering the frequency band 1805 ~ 1880 MHz.
4. TC-VCXO (OSC900)
To generate the 13MHz reference clock to drive the logic and RF.
After additional process, the reference clock applies to the U900 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. SI4206 (U900)
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 frequency
synthesizer. The RFLO frequency is between 1737.8 ~ 1989.9 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).
Also, this chip down-converts the ADC output to baseband with a digital 100 KHz quadrature LO signal. Digital
decimation and IIR filters perform channel selection to remove blocking and reference interface signals.
After channel selection, the digital output is scaled with a digital PGA, which is controlled with the DGAIN. DACs drive
a differential analog signal onto the RXIP, RXIN, RXQP, RXQN pins to interface to standard analog-input baseband IC.

2. Baseband Circuit description of SGH-C200
1) CSP2200B1
1. Power Management
Seven low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal
system performance and long battery life. A programmable LDO 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 two
LED drivers and two call-alert drivers, aid in reducing both board area and system complexity. A four-wire serial interface
unit(SIU) provides access to control and configuration registers. This interface gives a microprocessor full control of the
CSP2200B1 and enables system designers to maximize both standby and talk times. Error reporting is provided via an
interrupt signal and status register. Supervisory functions. including a reset generator, an input voltage monitor, and a
thermal monitor, 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).
2. Battery Charge Management
A battery charge management block, incorporating an internal PMOS switch, and an 8-bit ADC, provides fast, efficient
charging of single-cell Li-Ion battery. Used in conjunction with a current-limited voltage source, this block safely
conditions near-dead cells and provides the option of having fast-charge and top-off controlled internally or by the system's
microprocessor.
3. Backlight LED Driver
The backlight LED driver is a low-side, programmable current source designed to control the brightness of the keyboard
illumination.
LED1_DRV is controlled via LED1_[0:2] and can be programmed to sink from 15mA to 60mA in 7.5mA
steps. LED2_DRV is controlled via LED2_[0:2] and can be programmed to sink from 5mA to 40mA in 5mA steps.
2-2

Circuit Description
Both LED drivers are capable of sinking their maximum output current at a worst-case maximum output voltage of 0.6V.
For efficient use, the LEDs is connected between the battery and the LED_DRV output.
4. Vibrator Motor Driver
The vibrator motor driver is a independent voltage regulator to drive a small dc motor that silently alerts the user of an
incoming call. The driver is a 3.0V constant source while sinking up to 180mA and controlled by enable signal of main
chip. For efficient use and safety, the vibrator motor should be connected between the regulator output and the ground.
2) Connector
1. LCD Connector
LCD is consisted of main LCD(color 65K STN LCD). Chip select signals of EMI part in the trident, LCD_CS, can
enable main LCD. LED+ signal enables white LED of main LCD. In sleep mode, white LED are turned off.
These two signals are from IO part of the DSP in the trident. RST signal from CSP2200B1 initiates the initial process of
the LCD.
16-bit data lines(D(0)~D(15)) transfers data and commands to LCD through emi_filter. Data and commands use A(2) signal.
If this signal is high, Inputs to LCD are commands. If it is low, Inputs to LCD are data.
The signals which inform the input or output state to LCD, are required. But this system is not necessary for read enable
signal. CP_WEN signal is only used to write data or commands to LCD.
Power signal for operating LCD driver is VCCD.
2. JTAG Connector
Trident has two JTAG ports which are for ARM core and DSP core(DSP16000). So this system has two port connector
for these ports. Pins' initials for ARM core are 'CP_' and pins' initials for DSP core are 'DSP_'.
CP_TDI and DSP_TDI signal are used for input of data. CP_TDO and DSP_TDO signals are used for the output of the
data. CP_TCK and DSP_TCK signals are used for clock because JTAG communication is a synchronous. CP_TMS and
DSP_TMS signals are test mode signals. The difference between these is the RESET_INT signal which is for ARM core
RESET.
3. Keypad connector
This is consisted of key interface pins in the trident, KEY_ROW[0~4] and KEY_COL[0~4]. These signals compose the
matrix. Result of matrix informs the key status to key interface in the trident. Some pins are connected to varistor for
ESD protection. And power on/off key is seperated from the matrix.
So power on/off signal is connected with CSP2200 to enable CSP2200.
Nine key LED use the +VBATT supply voltage. These are connected to BACKLIGHT signal in the CSP2200.
This signal enables LEDs with current control.

filtering.
3) IF connetor
It is 24-pin connector, and separated into two parts. One is a power supply part for main system. And the other is
designed to use SDS, DEBUG, DLC-DETECT, JIG_ON, VEXT, VTEST, VF, and GND. They connected to power supply
IC, microprocessor and signal processor IC.
4) Audio
AOUTAP, AOUTAN from CSP2200 is connected to the speaker via analog switch. AOUTBP and AOUTBN are connected
to the ear-mic speaker via ear-jack. MICIN and MICOUT are connected to the main MIC. And AUXIN and AUXOUT
are connected to the Ear-mic.
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 16 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 YMU762MA3 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. 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 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 YMU762MA3 directly interprets and plays blocks
relevant to synthesis (playing music and reproducing ADPCM with FM synthesizer) that are included in data distributed in
SMAF.

FCRAM to data lines. Each chip select signals in the trident select flash memory or SCRAM. Reading or writing
procedure is processed after CP_WEN or CP_OEN is enabled. Memories use FLASH_RESET, which is buffered signal of
RESET from CSP2200, for ESD protection. A[0] signal enables lower byte of FCRAM and UPPER_BYTE signal enables
higher byte of FCRAM.
6) Trident
Trident is consisted of ARM core and DSP core. It has 20K*16bits RAM 144K*16bits ROM in the DSP. It has
4K*32bits ROM and 2K*32bits RAM in the ARM core. DSP is consisted of timer, one bit input/output unit(BIO), JTAG,

DSP IP pins.
7) CSP2200
CSP2200 is integrated the timing and control functions for GSM 2+ mobile application with the ADC and DAC functions,
and power management block. The CSP2200 interfaces to the trident, via a 16-bit parallel interface. It serves as the
interface that connects a DSP to the RF circuitry in a GSM 2+ mobile telephone. DSP can load 148 bits of burst data
into CSP2200’
s internal register, and program CSP2200’
s event timing and control register with the exact time to send the

Circuit Description
burst. When the timing portion of the event timing and control register matches the internal quarter-bit counter and internal
frame counter, the 148 bits in the internal register are GMSK modulated according to GSM 2+ standards. The resulting
phase information is translated into I and Q differential output voltages that can be connected directly to an RF modulator
at the TXOP and TXON pins. The DSP is notified when the transmission is completed. For receiving baseband data, a
DSP can program CSP2200’
s event timing and control register with the exact time to start receiving I and Q samples
through TXIP and TXIN pins. When that time is reached, the control portion of the event timing and control register will
start the baseband receive section converting I and Q sample pairs. The samples are stored in a double-buffered register
until the register contains 32 sample pairs. CSP2200 then notifies the DSP which has sample time to read the information
out before the next 32 sample pairs are stored. The voice band ADC converter issues an interrupt to the DSP whenever it
finishes converting a 16-bit PCM word. The DSP then reads the new input sample and simultaneously loads the voice
band output DAC converter with a new PCM output word. The voice band output can be connected directly to a speaker
via AOUTAN and AOUTAP pins and be connected to a Ear-mic speaker via AOUTBN and AOUTBP pins.
There are 7 LDOs which are power sources of microprocessor, LCD, etc. These 7 LDOs output are programmable.
8) X-TAL(13MHz)
This system uses the 13MHz TCXO, TCO-9141B, Toyocom. AFC control signal form CSP1093 controls frequency from
13MHz x-tal. It generates the clock frequency. This clock is fed to CSP1093,Trident,YMU762 and Silab solution.
