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. — Si4210 (U100) 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.

2-2. Baseband Circuit description of SGH-C230 2-2-1. CSP2200B1 — 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 selfresetting, 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). — 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.

2-2-7. 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. 2-5

Circuit Description
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.
