4. Crystal (U802)
To generate the 26MHz reference clock to drive the logic and RF.
After additional process, the reference clock applies to the U801 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. Si4210 (U801)
The receive section integrates four differential-input low noise amplifiers LNAs supporting the GSM850, EGSM900,
DCS1800 and PCS1900 bands. The LNA inputs are matched to the 150 ohm balanced-output SAW filters through externa
LC matching network.
A quadrature Image-reject mixer downconverts the RF signal to a 200 KHz intermediate frequency(IF). The mixer output is
amplified with an analog programmable gain amplifier(PGA) that is controlled with the AGAIN. The quadrature IF ? ?
is digitized with high resolution analog-to-digital converts (ADC).
The ADC output is downconverted to baseband with a digital quadrature LO signal. Digital decimation and FIR filters
perform digital filtering and remove ADC quantization noise, blockers and reference interferers.
After filtering, the digital output is scaled with a digital PGA, which is controlled with the DGAIN. DACs drive a
differential I and Q analog signal onto the BIP, BIN, BQP and BQN pins to interface to standard analog-input baseband
ICs.

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.

incoming call. The driver is a 3.3V constant source while sinking up to 140mA 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.
8-bit data lines(D(0)~D(7)) 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.

Circuit Description
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
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.
