1) PSC2106 & LTC 1734
1. Power Management
Seven low-dropout regulators designed specifically for GSM applicationspower the terminal and help ensure optimal system performance and longbattery life.A programmable boost converter provides support for 1.8V, and 3.0V SIMs,while a self-resetting, electronically fused switch supplies power to externalaccessories. Ancillary support functions, such as an LED driver and twocall-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 ofthe PSC2106 and enables system designers to maximize both standby andtalk times.Supervisory functions. including a reset generator, an input voltage monitor,and a thermal monitor, support reliable system design. These functionswork together to ensure proper system behavior during start-up or in theevent of a fault condition(low microprocessor voltage, insufficient batteryenergy, or excessive die temperature).
2. Battery Charge Management
A battery charge management block provides fast, efficient charging of asingle-cell Li-ion battery. Used in conjunction with a current-limited voltagesource and an external PMOS pass transistor, this block safely conditionsnear-dead cells and provides the option of having fast-charge and top-offcontrolled internally or by the system's microprocessor.
3. Backlight LED Driver
The backlight LED drivers are low-side, programmable current sourcedesigned to control the brightness the keyboard and LCD illumination.LED1_DRV is controlled via LED1_[0:2] and can be programmed to sinkfrom 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 LEDdrivers are capable of sinking their maximum output current at a worstworst case maximum output voltage of 0.6V. For efficient use, the LEDsshould be forward connected between the ma battery and theircorresponding LED driver output.

1. LCD Connector
LCD is consisted of main LCD(color 65K TFD LCD). Chip select signals ofEMI 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 2106initiates the initial process of the LCD.16-bit data lines(D(0)~D(15)) transfers data and commands to LCD throughemi_filter. Data and commands use A(2) signal. If this signal is high, Inputsto LCD are commands. If it is low, Inputs to LCD are data. The signalwhich informs the input or output state to LCD, is required. But this systemis not necessary this signal. So CP_WEN signal is used to write data orcommands to LCD.Power signals for LCD are V_bat and V_ccd.SPK1P and SPK1N from CSP1093 are used for audio speaker. And VIB_ENfrom enables the motor.
2. JTAG Connector
Trident has two JTAG ports which are for ARM core and DSPcore(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 andDSP_TDO signals are used for the output of the data. CP_TCK andDSP_TCK signals are used for clock because JTAG communication is asynchronous. CP_TMS and DSP_TMS signals are test mode signals. Thedifference between these is the RESET_INT signal which is for ARM coreRESET.
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.

Sincethe device is capable of simultaneously generating up to synchronous with theplay of the FM synthesizer, various sampled voices can be used as soundeffects.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 canflexiblysupport application such as incoming call melody music distributionservice. The hardware sequencer built in this device allows playing of thecomplex music without giving excessive load to the CPU of the portabletelephones. Moreover, the registers of the FM synthesizer can be operateddirectly for real time sound generation, allowing, for example, utilization ofvarious sound effects when using the game software installed in the portabletelephone.YMU759 includes a speaker amplifier with high ripple removal rate whosemaximum output is 550mW (SPVDD=3.6V). The device is also equipped withconventional function including a vibartor and a circuit for controlling LEDssynchornous 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 adata distribution format that is compatible wiht multimedia. Since the SMAFtakes a structure that sets importance on the synchronization between soundand images, various contents can be written into it including incoming callmelody with words that can be used for traning karaoke, and commercialchannel that combines texts, images and sounds, and others. The hardwaresequencer of YMU762MA3 directly interprets and plays blocks relevant tosysthesis (playing music and reproducing ADPCM with FM synthesizer) that areincluded in data distributed in SMAF.
The vibrator motor driver is a low-side, programmable voltage source designedto drive a small dc motor that silently alerts the user of an incoming call. Thedriver 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

7) CSP1093
CSP1093 integrates the timing and control functions for GSM 2+ mobileapplication with the ADC and DAC functions. The CSP1093 interfaces to thetrident, via a 16-bit parallel interface. It serves as the interface that connectsa DSP to the RF circuitry in a GSM 2+ mobile telephone. DSP can load 148bits of burst data into CSP1093’s internal register, and program CSP1093’sevent timing and control register with the exact time to send the burst. Whenthe timing portion of the event timing and control register matches the internalquarter-bit counter and internal frame counter, the 148 bits in the internalregister are GMSK modulated according to GSM 2+ standards. The resultingphase information is translated into I and Q differential output voltages that canbe connected directly to an RF modulator at the TXOP and TXON pins. TheDSP is notified when the transmission is completed. For receiving basebanddata, a DSP can program CSP1093’s event timing and control register with theexact 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 controlregister will start the baseband receive section converting I and Q samplepairs. The samples are stored in a double-buffered register until the registercontains 32 sample pairs. CSP1093 then notifies the DSP which has ample timeto read the information out before the next 32 sample pairs are stored. Thevoice band ADC converter issues an interrupt to the DSP whenever it finishesconverting a 16-bit PCM word. The DSP then reads the new input sample andsimultaneously loads the voice band output DAC converter with a new PCMoutput word. The voice band output can be connected directly to a speaker viaAOUTAN and AOUTAP pins and be connected to a Ear-mic speaker viaAOUTBN and AOUTBP pins.
8) X-TAL(13MHz)
This system uses the 13MHz TCXO, TCO-9141B, Toyocom. AFC control signalform CSP1093 controls frequency from 13MHz x-tal. It generates the clockfrequency. This clock is fed to CSP1093,Trident,YMU759 and Silab solution.
