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) TX PART 

Baseband IQ signal fed into offset PLL, this function is included inside of U404 chip. 

SI4205 chip generates modulator signal which power level is about 1.5dBm and fed into Power Amplifier(U403). 

The PA output power and power ramping are well controlled by Auto Power Control circuit. We use offset PLL below

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. 

 


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, . 

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. 

 


8) 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, 

EMI and HDS(Hardware Development System). ARM core is consisted of EMI, PIC(Programmable Interrupt Controller), 

reset/power/clock unit, DMA controller, TIC(Test Interface Controller), peripheral bridge, PPI, SSI(Synchronous Serial 

Interface), ACCs(Asynchronous communications controllers), timer, ADC, RTC(Real-Time Clock) and keyboard interface. 

DSP_AB[0~8], address lines of DSP core and DSP_DB[0~15], data lines of DSP core are connected to CSP2200. A[0~20], 

address lines of ARM core and D[0~15], data lines of ARM core are connected to memory, LCD and YMU762. 

ICP(Interprocessor Communication Port) controls the communication between ARM core and DSP core. 

CSROMEN, CSRAMEN and CS1N to CS4N in the ARM core are connected to each memory. WEN and OEN control the 

process of memory. External IRQ(Interrupt ReQuest) signals from each units, such as, YMU, Ear-jack, Ear-mic and 

CSP1093, need the compatible process. 

Some PPI pins has many special functions. CP_KB[0~9] receive the status from key FPCB and are used for the 

communications using data link cable(DEBUG_DTR/RTS/TXD/RXD/CTS/DSR). 

And UP_CS/SCLK/SDI, control signals for CSP2200 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. 

8) X-TAL(13MHz) 

This system uses the 13MHz TCXO. AFC control signal form CSP1093 controls frequency from 13MHz x-tal. This clock 

is fed to CSP1093,Trident,YMU759 and Silab solution.
