1.2 Regulatory Information A. Security Toll fraud, the unauthorized use of telecommunications system by an unauthorized part (for example, persons other than your company’s employees, agents, subcontractors, or person working on your company’s behalf) can result in substantial additional charges for your telecommunications services. System users are responsible for the security of own system. There are may be risks of toll fraud associated with your telecommunications system. System users are responsible for programming and configuring the equipment to prevent unauthorized use. The manufacturer does not warrant that this product is immune from the above case but will prevent unauthorized use of common-carrier telecommunication service of facilities accessed through or connected to it. The manufacturer will not be responsible for any charges that result from such unauthorized use.

B. Incidence of Harm If a telephone company determines that the equipment provided to customer is faulty and possibly causing harm or interruption in service to the telephone network, it should disconnect telephone service until repair can be done. A telephone company may temporarily disconnect service as long as repair is not done. C. Changes in Service A local telephone company may make changes in its communications facilities or procedure. If these changes could reasonably be expected to affect the use of the this phone or compatibility with the network, the telephone company is required to give advanced written notice to the user, allowing the user to take appropriate steps to maintain telephone service. D. Maintenance Limitations Maintenance limitations on this model must be performed only by the manufacturer or its authorized agent. The user may not make any changes and/or repairs expect as specifically noted in this manual. Therefore, note that unauthorized alternations or repair may affect the regulatory status of the system and may void any remaining warranty.

3. TECHNICAL BRIEF 3.1 GENERAL DESCRIPTION The LG-P990 supports UMTS-900, UMTS-1900, UMTS-2100, GSM-850, GSM-850, GSM-900, GSM-1800, and GSM1900 based GSM/GPRS/EDGE/UMTS. All receivers and the UMTS transmitter use the radioOne1Zero-IF architecture to eliminate intermediate frequencies, directly converting signals between RF and baseband. The quad-band GSM transmitters use a baseband-to-IF upconversion followed by an offset phase-locked loop that translates the GMSK-modulated or 8-PSK-modulated signal to RF.

3. Technical Brief

Receiver Section For the RX section the IC features 5 RX inputs, 4 of those might be used for multi mode receive, this means they can be used for GSM and UMTS (the IC can be reconfigured to achieve in spec performance) operation. The band I input is for UMTS operation only. The multi mode inputs may alternatively be configured to be first LNA (for GSM) or LNA2 (UMTS) when an additional external LNA and interstage filter is used. The receiver structure is optimized for compressed mode operation, thus only a single base band chain is used, saving area and optimizes power consumption.The receiver AGC can be aligned to the UMTS frame structure with the TAS macro SYNC3G. Transmitter Section The TX features 6 RF outputs, which are directly matched to 50 ȳ impedance for easy connection to external power amplifiers, which reduces significantly external component count. 2 outputs are high power, small signal polar modulated outputs for the GSM system, with low sensitivity to PA harmonics. They are capable to perform GMSK or 8-PSK modulation signals with excellent noise performance, thus no interstage filter in between transceiver and PA is required. The low band output covers the 850 and the 900 MHz GSM bands, the mid band output covers the 1800 and 1900 MHz bands. The UMTS outputs are vector modulated single ended high output power driver amplifiers, with excellent EVM and adjacent channel leakage performance. Together with external UMTS power amplifier modules all bands except band VII can be addressed. There is one driver for all low bands (850 and 900 MHz bands), two drivers for the mid bands (1700 - 1900 MHz bands) and one driver for the high band (2100 MHz band). Thus many band combinations can be supported by the transceiver. The IC features additionally closed loop power control for GSM and for UMTS, thus supporting TRP requirements in cooperation with the power amplifier and the antenna design. There is one input pin for the power detector voltage coming from the PA, the complete loop circuits are implemented in the digital domain, which enables a high reliability of the loop performance for both standards. Interfaces The base band is connected via a DigRF V3.09 high speed data interface with a maximum clock frequency of 312 MHz. The pure digital interface enables the digital baseband to shrink efficiently, as all the analog functionality is within the RFIC. All data and control traffic is multiplexed via the RX and TX interface lines. The IC features a high level programming model enabling the complete compressed mode operation of the device in an RF engine environment.It handles RX and TX power control, also incorporating the calibration data. The complete timing is optimized for compressed mode operation of the transceiver, it controls the front end components of the engine (PA´s, switches, LNA´s). Additionally a SPI control bus for front end component control is available in the IC, which also enables the readback of data from external components, thus the handling of functions like PA saturation, mismatch detection, overheating (incorporated in the closed loop power control) can be adopted. AFC Control The AFC control is maintained by providing a voltage generated by a 12-Bit DAC to the external TCVCXO module, which means the reference clock is synchronized to the system frequency.

3.2 GSM MODE 3.2.1 GSM RECEIVER The GSM-850/GSM-1800, receiver inputs of PMB5703 are connected directly to the transceiver front-end Module. The GSM-900/GSM-1900 receiver inputs are using the Rx path with WCDMA1900 and WCDMA900 bands. The GSM-850, GSM-900, GSM-1800, and GSM-1900 receiver inputs use differential configurations to improve common-mode rejection and second-order non-linearity performance. Figure 3-1 shows the line-up for the 2G receiver chain for bands serving only GSM. The RX digital front-end (DFE) contains all digital signal processing. Blue arrows show gain switching inputs of the signal processing stages. The signal path splits at the mixer input into an in-phase and an identical quadrature path. For simplicity the 2nd path is not shown in the figure. The quadrature downconverter translates the useful signal directly to baseband (zero-IF).

[Figure 2-2] 2G Receiver Line Up-GSM Multi Mode Setup Since GSM-850, GSM-900, GSM-1800, and GSM-1900 signals are time-division duplex (the handset can only receive or transmit at one time), switches are used to separate Rx and Tx signals in place of frequency duplexers – this is accomplished in the switch module. The GSM-850, GSM-900, GSM-1800, and GSM-1900 receive signals are routed to the PMB5703 through band selection filters and matching networks that transform single-ended 50-ΩG sources to differential impedances optimized for gain and noise figure. The PMB5703 input uses a differential configuration to improve second-order intermodulation and common mode rejection performance. The downconverted baseband outputs are multiplexed and routed to lowpass filters (one I and one Q) having passband and stopband characteristics suitable for GMSK or 8-PSK processing. These filter circuits include DC offset corrections.

3.3.2 UMTS TRANSMITTER Figure 3-4 shows a functional overview of the 3G transmitter chain implemented for RF signal processing. The IQ-chips, which are transferred via the digital interface, are stored in a FIFO. Then it depends on the setting of three signals how samples are consumed from the FIFO Buffer. Then the samples are fed into a CORDIC, which is used to shift the phase of the complex signal. The rootraisedcosine (RRC) filter performs the pulse shaping according to 3GPP. As the system clock is no integer multiple of the UMTS chip rate a fractional sample rate conversion (FSRC) is necessary. In the amplitude correction / offset correction (AC/OC) block the amplitude and the offset of the IQ-signal are modified. The final sample rate at the output of the digital front end is achieved in the interpolation / noise shaping block, where also the word length is reduced in order to fit to the D/A-converter resolution. After the DAC a post-filter reduces the level of the repetition spectrum and the analog noise in order to supply a clean signal to the IQ-modulator. The frequency conversion to the wanted TX-channel is done in a direct-up conversion IQ-modulator which is followed by a gain stage with a single ended high power output.

3. Technical Brief

In the PMB 5703 the receiver and the transmitter contain each a complete fractional-N sigma-delta synthesizer with fast locking. For GMSK/8-PSK RX operation mode a fractional-N sigma-delta synthesizer for the frequency synthesis is used. For GMSK/8-PSK TX operation mode the fractional-N sigma-delta synthesizer is used as a Sigma-Delta modulation loop to process the phase/frequency signal. A 26 MHz reference signal (provided by an internal clock generation block) serves as comparison frequency of the phase detector. In GMSK/8-PSK mode the divider in the feedback path of the synthesizer is carried out as a multi-modulus divider (MMD). The GMSK/8-PSK loop filter is fully integrated and the loop bandwidth is about 100 kHz to allow the transfer of the phase modulation during GMSK/8-PSK operation. The open loop gain is automatically adjusted prior to each GMSK/8PSK slot . To overcome the statistical spread of the loopfilter element values an automatic loopfilter adjustment is performed before each GMSK/8-PSK synthesizer startup. The fully integrated GMSK/8-PSK quad-band VCO is designed for the four GMSK/8-PSK bands (850, 900, 1800,1900 MHz) and operates at double (for GSM1800 and GSM1900 band) or four times (for GSM850 and GSM900 band) of the transmit or receive frequency. To cover the wide frequency range the VCO is automatically aligned by a binary automatic band selection before the settling process of the synthesizer starts. In UMTS TX and RX mode a fractional-N sigma-delta synthesizer for the frequency synthesis is used. The implemented divider in the feedback path of the synthesizer is carried out as a multi-modulus divider (MMD). Also the 26 MHz reference signal serves as comparison frequency of the phase detector. The UMTS loop filter is fully integrated and the loop bandwidth is about 180 kHz. The open loop gain is automatically adjusted prior each UMTS channel programming. The two fully integrated UMTS VCOs are designed for the UMTS bands (I, II, III, IV, V, VI, VIII, IX and X) and operates at double (for bands I, II, III, IV, IX and X) or four times (for bands V, VI and VIII) of the transmit or receive frequency. To cover the wide frequency range the VCOs are automatically aligned by a binary automatic band selection before the settling process of the synthesizer starts. G

3.6.2 26MHz VCTCXO (X101, DSA221SCL) The Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) provides the reference frequency for all RFIC synthesizers as well as clock generation functions within the PMB5703 IC. The oscillator frequency is controlled by the PMB5703 ICs. TRK_LO_ADJ pulse density modulated signal in the same manner as the transmit gain control TX_AGC_ADJ. A two-pole RC lowpass filter is recommended on this control line. The PM7540 IC controls the handset power-up sequence, including a special VCTCXO warm-up interval before other circuits are turned on. This warm-up interval (as well as other TCXO controller functions) is enabled by the MSM TCXO_EN line . The PM7540 IC VREG_TCXO regulated output voltage is used to power the VCTCXO and is enabled before most other regulated outputs. Any GSM mode power control circuits within the MSM7227 IC require a reference voltage for proper operation and sufficient accuracy. Connecting the PM7540 IC REF_OUT directly to the MSM7227 IC GSM_PA_PWR_CTL_REF provides this reference. This sensitive analog signal needs a 0.1 μF low frequency filter near to MSM side, and isolate from digital logic and clock traces with ground on both sides, plus ground above and below if routed on internal layers.

3.6.3 FEM + GSM PAM (U104, SKY77529) The SKY77529 Tx Front End Module (FEM) is designed in a compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, PCS1900, supporting GMSK and linear EDGE modulation. Class 12 General Packet Radio Service (GPRS) multi-slot operation is also supported. The module consists of a GSM850/900 PA block and a DCS1800/PCS1900 PA block, a printed directional coupler for each block impedance-matching circuitry for 50 Ω input and output impedances, a multifunction power amplifier control (MFC) block, low pass harmonic rejection filters, and an SP8T Antenna T/R switch. Two separate Hetero junction Bipolar Transistor (HBT) PA blocks are fabricated onto an InGaP die; one supports the GSM850/900 bands, the other supports the DCS1800 and PCS1900 bands. The InGaP PA die, the silicon MFC die, PHEMT switch die, and the passive components are mounted on a multi-layer laminate substrate. The assembly is encapsulated with plastic overmold. The FEM incorporates full support for a Serial Peripheral Interface (SPI) bus function. The SPI controller shall accept SPI telegrams with data fields that support PA and switchplexer-related functions. All FEM operating modes and switch states shall be determined by the SPI telegram. The Multi-function Control (MFC) provides pin out for interoperation with a specified transceiver that will establish a closed loop power control mechanism. The external circuit uses the Linear Detector output to set a fixed bias point for 8PSK (EDGE) mode and a variable bias point for GMSK (GSM) mode. The power control loop together with the MFC will reduce sensitivity to antenna load, input drive, temperature, power supply, and process variation. The combined circuit configures the PA for fixed gain in 8PSK mode while providing the ability to optimize the PA bias at different power levels to maximize efficiency.

3.9 Subsystem (PMB9801_X-GOLDTM616) 3.9.1 ARM Microprocessor Subsystem The ARM1176JZ-S incorporates an integer unit that implements the ARM11 ARM architecture v6. The core supports the 32-bit ARM and 16-bit Thumb instruction sets, Jazelle technology to enable direct execution of Java byte codes and a range of SIMD DSP instructions that operate on 16-bit or 8bit values in 32-bit registers.

3.9.2 WCDMA Subsystem The 3.5G cellular modem is implemented as an independent Layer1 subsystem including a separate microcontroller. The X-GOLDTM616 Modem core acts as a master controlling the 3.5G cellular Modem slave via the Layer1 host controller interface.

3.9.3 GSM Subsystem The X-GOLDTM616 is suited for mobile stateons operating in the GSM850/900/1800/1900 band. In the receiver path the antenna input signal is converted to the base band, filtered, and amplified to target level by the RF transceiver chip set. Tne modem processor performs for both, GMSK and 8-PSK, the complex baseband signal equalization with soft-output recovery and the channel decoding supported by a Viterbi hardware accelerator.

3.9.4 RF Interface The RF interface communicates with the mobile station’s external RF and analog baseband circuits. Signals to these circuits control signal gain in the Rx and Tx signal path and maintain The system’s frequency reference.

3.9.5 SPI based IPC The XMM™6160 platform supports the serial connection via SPI. The command flow of the IPC is independent from the HW solution and the IPC protocol. It is implemented using a logical channel multiplexer and AT commands. The IPC hardware interface consists of a serial SPI interface and two control signals, and one additional optional control signal. The SPI is implemented using the USIF2 of the X-GOLD™616, with the GPIO’s implementing sleep mode and readiness handling

3.9.6 Audio function Audio Processing on ARM Core The ARM™1176 core is mainly in charge of “audio application” tasks, including audio playback, audio streaming and audio recording if required. This implies the usage of codec algorithms such as MP3, WMA, AAC etc., which must be implemented as decoder and/or encoder software on the ARM core. Decoded audio streams are transmitted as PCM samples to the DSP core via a shared memory. Audio streams to be encoded are transmitted by the DSP to the ARM core via a shared memory. The ARM can also generate ring tones and service tones to notify an incoming call, an incoming message or any audio notification of a phone´s event (warning, error, confirmation, battery low, etc.). Another activity on the audio side for the ARM is the streaming of compressed audio data over the UART interface to the Bluetooth chip for A2DP usage (Advanced Audio Distribution Profile: audio playback over Bluetooth). Via the same interface it communicates with the Bluetooth chip (this is not restricted to audio activities). The ARM core is managing the configuration of the AFE by sending commands to the DSP over shared memory to activate various configurations of the AFE. Note that the activities of the ARM remain purely digital audio processing.

3. Technical Brief

Audio Processing on DSP Core The DSP core is in charge of “speech audio” and mixing tasks and its activities remain - as the ARM - purely digital audio. The DSP can also execute some “audio application” tasks. It ensures the simultaneous encoding and decoding of speech audio frames during telephone conversation. It uses different sets of vocoders as specified by the applicable standards for the ongoing telephone conversation. On the audio out path (i.e. towards the speaker) it mixes “audio application” received over shared memory with decoded speech audio. On this path it can also mix some audio samples coming from the microphone to enable the feedback loop to the speaker (Sidetone generation, as specified in 3GPP/ TS 43.050, chapter 3.10). On the audio in path (i.e. from the microphone to the transmission of the encoded audio samples over the air) the DSP can also mix speech audio samples with any other digital audio source and analogue FM radio as well. The mixing capabilities are extremely broad as the cases mentioned above are only examples. These mixing capabilities also include the ability to execute a sample rate conversion to bring all samples to the same rate before mixing. The DSP also can execute some audio application tasks such as PCM, ADPCM, SB-ADPCM audio playback and recording. Simple Tone (sine tones, DTMF, key click) can be generated as well. The next activity of the DSP is transferring data to and from the hardware peripherals (AFE, I2S0 and I2S1). Asmentioned in Figure 1 a fifo buffer is used to exchange stereo audio samples between the DSP and the AFE on the microphone path and speaker path. When receiving a command from the ARM the DSP directly configures the different modes of the AFE. The DSP also manages the I2S interfaces I2S0 and I2S1. I2S0 interface, configured as master interface, is used to exchange speech audio samples at a rate of 8 or 16 kHz mono on both directions with the Bluetooth chip in the case of a speech call using a Bluetooth headset. The I2S1 interface can be used as slave or master interface, enabling the exchange of audio stereo samples at any common rate between 8 and 48 kHz, potentially asymmetrically between RX and TX. This is to act as an audio bridge with an external audio chip (application processor, audio processor,etc.). Note that the activities of the DSP - like the ARM - remain purely digital audio processing. Refer to the document “system requirements specification” for more details on the different audio application features supported by the chip. Audio Processing on Audio Front End The AFE is used as a playback and capture device, i.e. exchanging digital audio stereo samples on both directions (from microphone to DSP and from ARM/DSP to speaker). On audio-in path analog to digital conversion and amplification is executed. On the audio-out path digital to analog conversion and power amplification is performed. Additionally, the AFE physically selects the correct audio analog paths and is directly managing the analog inputs and outputs.

The X-GOLD also holds a measurement unit that can perform all necessary battery measurements through external HW. This is sufficient for a modem only design where charging is controlled by another chip G

3.9.10 Clocking The clocking system is based on 2 different clocks, a 26 MHz reference clock generated within the RF Engine and a 32 kHz real-time clock (RTC) generated in the baseband.The 26 MHz clock provided by the RF engine is the main reference clock for the RF circuit and the X-GOLD™616. Also other system components may be supplied with 26 MHz reference clocks. A 32 kHz oscillator located at the X-GOLD™616 supplies the RTC with the reference clock for the real time clock application, as well as provides a low power standby clock for system sleep mode operation. This clock is available also for other system components like GPS. .

Battery Voltage Regulation (CV Mode) The battery voltage regulation feedback is through BATT pin. The RT9524 monitors the battery valrage vetween BATT and GND pins. When the battery voltage closes to battery regulation voltage threshold, the voltage regulation phase begins and the charging current falls below the programmed end-of-charge current threshold, the CHG_S pin gose high to indicate the termination of charge cycle. The end-of-charge cyrrent threshold is set by the IEOC pin. The resistor Rieoc is connected to IEOC and GND. The parameters Kieoc and IEOC are specified in the specification table. IEOC(%) = RIEOC 200 The current threshold of IEOC (%) is defined as the percentage of fast-charge current set by Riset. After the CHGSB pin pulled to high, the RT9524 still monitors the vattery voltage. Charge current is resymed when the battery voltagr goes to lower then the battery regulation voltage threshold.

3.12.3 Audio codec(Wolfson_wm8994) The WM8994is a highly integrated ultra-low power hi-fi CODEC designed for smart phones and other portable devices rich in multimedia features. An integrated stereo class D/AB speaker driver and class W headphone driver minimize power consumption during audio playback. The device requires only two voltage supplies, with all other internal supply rails generated from integrated LDOs. Stereo full duplex asynchronous sample rate conversion and multi-channel digital mixing combined with powerful analogue mixing allow the device to support a huge range of different architectures and use cases. A fully programmable parametric EQ provides speaker compensation and a dynamic range controller can be used in the ADC or DAC paths for maintaining a constant signal level, maximizing loudness and protecting speakers against overloading and clipping. A smart digital microphone interface provides power regulation, a low jitter clock output and decimation filters for up to four digital microphones. A MIC activity detect with interrupt is available. Active ground loop noise rejection and DC offset correction help prevent pop noise and suppress ground noise on the headphone outputs.
