1) PSC2106 & LTC 1734 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 boost converter provides support for 1.8V, and 3.0V SIMs, while a self-resetting, electronically fused switch supplies power to external accessories. Ancillary support functions, such as an LED driver and two call-alert drivers, aid in reducing both board area and system complexity. A three-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. 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 provides fast, efficient charging of a single-cell Li-ion battery. Used in conjunction with a current-limited voltage source and an external PMOS pass transistor, 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 drivers are low-side, programmable current source designed to control the brightness the keyboard and LCD illumination. LED1_DRV is controlled via LED1_[0:2] and can be programmed to sink from mA to 60mA in 7.5mA steps. LED2_DRV is controlled via LED2_[0:2] and can be programmed to sink from 5 to 40mA in 5mA steps. Both LED drivers are capable of sinking their maximum output current at a worst worst case maximum output voltage of 0.6V. For efficient use, the LEDs should be forward connected between the ma battery and their corresponding LED driver output. 2-3 SAMSUNG Proprietary-Contents may change without notice This Document can not be used without Samsung's authorization

2) Connector 1. LCD Connector LCD is consisted of main LCD(color 65K TFD LCD). Chip select signals of EMI part in the trident, CAM_CLCD_EN, can enable main LCD. LED_EN signal enables white LED of main LCD. This signal is 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 V_bat and V_ccd. SPK1P and SPK1N from CSP1093 are used for audio speaker. And VIB_EN from 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. 3. IRDA This system uses IRDA module, HSDL_3201, HP's. This has signals, IRDA_EN(enable signal), IRDA_RX(input data) and IRDA_TX(output data). These signals are connected to PPI of trident. It uses two power signals. V_ccd is used for circuit and V_bat is used for LED. 3) IF connetor It is 18-pin connector. They are designed to use SDS, DEBUG, DLC-DETECT, JIG_ON, VEXT, VTEST, VF, CF, VBAT and GND.

4) Audio AOUTAP from CSP1093 is connected to the main speaker. AOUTAN is connected to the speaker via audio-amp. AOUTBN and AOUTBP are connected to the ear-mic speaker via ear-jack. MICIN and MICOUT are connected to the main MIC. And AUXIN and AUXOUT are connected to the Ear-mic. YMU762MA3 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, YMU762MA3 is equipped 16 voices with differenttones. 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 YMU762MA3 are interpreted at anytime through FIFO, the length of the data(playing period) is not limited, so the device can flexiblysupport 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. For the headphone, it is provided with a stereophonic output terminal. For the purpose of enabling YMU762MA3 to demonstarte its full capablities, Yamaha purpose to use "SMAF:Synthetic music Mobile Application Format" as a data distribution format that is compatible wiht multimedia. Since the SMAF takes a structure that sets importance on the synchronization between sound and images, various contents can be written into it including incoming call melody with words that can be used for traning karaoke, and commercial channel that combines texts, images and sounds, and others. The hardware sequencer of YMU762MA3 directly interprets and plays blocks relevant to systhesis (playing music and reproducing ADPCM with FM synthesizer) that are included in data distributed in SMAF. 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 enabled by EN_VIB, and its voltage setting is determined by VIB[0:2]. Provided EN_VIB is a logic 1, the driver can be programmed to maintain a 2-5

SGH-P400 Circuit Description
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,YMU759 and Silab solution.
