3. FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band. - GSM FILTER (U402(SWITCHPLEXER+FILTER)) → For filtering the frequency band between 925 ~ 960 MHz - DCS FILTER(U402(SWITCHPLEXER+FILTER)) → For filtering the frequency band 1805 and 1880 MHz.
4. VC-TCXO (OSC401) 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. SI 4205 (U404) 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 1849.8~1879.9MHz. 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-N700 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). LCD LCD is consisted of main LCD(B/W STN LCD). Chip select signals of EMI part in the trident, LCD_CS, can enable main LCD. VDD_EL signal enables EL of main LCD. In sleep mode,
EL 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 . 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.
3). 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.
4). Keypad 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.

5) IF connetor It is 18-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, TA, VF, and GND. They connected to power supply IC, microprocessor and signal processor IC. 6) Audio AOUTAP, AOUTAN from CSP2200 is connected to the speaker via analog switch.
MICIN and MICOUT are connected
to the main MIC. YMU759 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, YMU759 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 YMU759 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. YMU759 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. 7) Memory This system uses AMD's memory,
S71JL064HA0BAW110.
It is consisted of 64M bits flash memory and 16M bits PSRAM. It has 16 bit data line, D[0~15] which is connected to trident, LCD or CSP2200. It has 22 bit address lines, A[0~21]. They are also connected. CP_CSROMEN signal, chip select signal in the trident, enable flash memories. They use 2.8 volt supply voltage, VCCD. During wrting process, CP_WEN is low and it enables writing process to flash memory and PSRAM. During reading process, CP_OEN is low and it output information which is located at the address from the trident in the flash memory or PSRAM to data lines. Each chip select signals in the trident select flash memory or PSRAM. Reading or writing procedure is processed after CP_WEN or CP_OEN is enabled. Memories use RST. A[0] signal enables lower byte of PSRAM and UPPER_BYTE signal enables higher byte of PSRAM.
