3. FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band. - GSM FILTER (C220,C221,L204) → For filtering the frequency band between 925 ~ 960 MHz - DCS FILTER (C218,C219,L203) → For filtering the frequency band 1805 and 1880 MHz. - PCS SAW FILTER (F200) → For filtering the frequency band between 1930 and 1990 MHz 4. TC-VCXO (OSC100) To generate the 13MHz reference clock to drive the logic and RF. After additional process, the reference clock applies to the U100 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. SI 4205 (U100) This chip integrates three differential-input LNAs. The GSM input supports the E-GSM, DCS input supports the DCS1800, PCS input supports the PCS1900. 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-X450 1) PSC2106 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 PSC2106 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 and LCD 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. 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 low-side, programmable voltage source designed to drive a small dc motor that silently alerts the user of an incoming call. The driver is controlled by VIB[0:1] and can be programmed to maintain a motor voltage of 1.3V, 2.0V, or 2.5V(relative to VBAT) while sinking up to 100mA. For efficient use, the vibrator motor should be connected between the main battery and the VIB_DRV output.

2) Connector 1. LCD Connector LCD is consisted of main LCD(color 65K UFB LCD). Chip select signals of EMI part in the trident, CLCD_EN, can enable main LCD. LED_EN signal enables white LED of main LCD and EL_EN signal enables dimming mode of main LCD. These two signals are from IO part of the DSP in the trident. RST signal from 2106 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 signal which informs the input or output state to LCD, is required. But this system is not necessary this signal. So CP_WEN signal is used to write data or commands to LCD. Power signals for LCD are +VBATT and VCCD. SPK1P and SPK1N from CSP1093 are used for audio speaker. And YMU_VIB_EN from MA-3 enables the motor. 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.

SGH-X450 Circuit Description

Some PPI pins has many special functions. CP_KB[0~9] receive the status from key FPCB and are used for the communicatios using data link cable(DEBUG_DTR/RTS/TXD/RXD/CTS/DSR). And UP_CS/SCLK/SDI, control signals for PSC2106 are outputted through PPI pins. It has signal port for charging(CHG_DET), SIM_RESET and FLIP_SNS with which we knows open.closed status of folder. It has JTAG control pins(TDI/TDO/TCK) for ARM core and DSP core. It recieves 13MHz clock in CKI pin from external TCXO and receives 32.768KHz clock from X1RTC. ADC(Analog to Digital Convertor) part receives the status of temperature, battery type and battery voltage. And control signals(DSP_INT, DSP_IO and DSP_RWN) for DSP core are used. It enables main LCD with DSP IP pins.

7) CSP1093 CSP1093 integrates the timing and control functions for GSM 2+ mobile application with the ADC and DAC functions. The CSP1093 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 CSP1093’ s internal register, and program CSP1093’ 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 CSP1093’ 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. CSP1093 then notifies the DSP which has ample 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.

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.
