3.1 General Description

The L-04C supports UMTS-800, UMTS-2100, GSM-900, DCS-1800, and PCS-1900 based GSM/GPRS/UMTS. All receivers and the UMTS transmitter use the radioOne1Zero-IF architecture to eliminate intermediate frequencies, directly converting signals between RF and baseband. The tri-band GSM transmitters use a baseband-to-IF up conversion followed by an offset phase-locked loop that translates the GMSK-modulated or 8-PSK-modulated signal to RF.

Fig 1.1-1 Block diagram of RF part

A generic, high-level functional block diagram of L-04C is shown in Figure 1-1. One antenna collects base station forward link signals and radiates handset reverse link signals. The antenna connects with receive and transmit paths through a FEM(Front End Module) (plus two duplexers for UMTS high-band and low-band operations).

The UMTS receive paths each include an LNA, an RF band-pass filter, and a downconverter that translate the signal directly from RF-to-baseband using radioOne ZIF techniques.

The high-band UMTS receive path and low-band path are accommodated in the RTR6285 IC. The RFIC.s Rx analog baseband outputs, for the receive chains, connect to the MSM IC. The UMTS and GSM Rx baseband outputs share the same inputs to the MSM IC .

For the transmit chains, the RTR6285 IC directly translates the Tx baseband signals (from the MSM device) to an RF signal using an internal LO generated by integrated on-chip PLL and VCO. The RTR6285 IC outputs deliver fairly high-level RF signals that are first filtered by Tx SAWs and then amplified by their respective UMTS PAs. The high- and low-band UMTS RF transmit signals emerge from the RTR6285 transceiver.

In the GSM receive path, the received RF signals are applied through their band-pass filters and down-converted directly to baseband in the RTR6285 transceiver IC. These baseband outputs are shared with the UMTS receiver and routed to the MSM IC for further signal processing. .

The GSM transmit path employs one stage of up-conversion and, in order to improve efficiency, is divided into phase and amplitude components to produce an open-loop Polar topology:

1. The on-chip quadrature up-converter translates the GMSK-modulated signal or 8-PSK modulated signal, to a constant envelope phase signal at RF;

2. The amplitude-modulated (AM) component is applied to the ramping control pin of Polar power amplifier from a DAC within the MSM

L-04C power supply voltages are managed and regulated by the PM7540 Power Management IC. This versatile device integrates all wireless handset power management, general housekeeping, and user interface support functions into a single mixed signal IC. It monitors and controls the external power source and coordinates battery recharging while maintaining the handset supply voltages using low dropout, programmable regulators.

The device’s general housekeeping functions include an ADC and analog multiplexer circuit for monitoring on-chip voltage sources, charging status, and current flow, as well as user-defined off-chip variables such as temperature, RF output power, and battery ID. Various oscillator, clock, and counter circuits support IC and higher-level handset functions. Key parameters such as under-voltage lockout and crystal oscillator signal presence are monitored to protect against detrimental conditions.

3.2 GSM Mode

3.2.1 GSM Receiver

The Dual-mode L-04C’s receiver functions are split between the three RFICs as follows:

■ UMTS-800, UMTS-2100, GSM-900, DCS-1800, and PCS-1900 modes use the RTR6285 IC only. Each mode has independent front-end circuits and down-converters, but they share common baseband circuits (with only one mode active at a time). All receiver control functions are beginning with SSBI-controlled parameters.

RF Front end consists of antenna, Front End Module(D5017) which includes nine path antenna SW and quad band GSM PAM(GSM850, GSM900, DCS, and PCS). The Front End Module allows multiple operating bands and modes to share the same antenna.

In L-04C, a common antenna connects to one of eight paths:

1) UMTS-800 Rx/Tx, 2) UMTS-2100 Rx/Tx, 3) GSM-900 Rx, 4) GSM-900 Tx,

5) DCS-1800 Rx, 6) PCS-1900 Rx, 7) DCS-1800 TX, 8) PCS-1900 TX.

UMTS operation requires simultaneous reception and transmission, so the UMTS Rx/Tx connection is routed to a duplexer that separates receive and transmit signals.

GSM850/GSM900, DCS, and PCS operation is time division duplexed, so only the receiver or transmitter is active at any time and a frequency duplexer is not required.

LGE Internal Use Only

The GSM900, DCS, and PCS receiver inputs of RTR6285 are connected directly to the transceiver front-end circuits(filters and antenna switch module). GSM900, DCS, and PCS receiver inputs use differential configurations to improve common-mode rejection and second-order non-linearity performance. The balance between the complementary signals is critical and must be maintained from the RF filter outputs all the way into the IC pins. The RTR6285 input stages include MSM-controlled gain adjustments that maximize receiver dynamic range.

Since GSM900, DCS, and PCS 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 amplifier outputs drive the RF ports of the quadrature RF-to-baseband downconverters. 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. The filter outputs are buffered and passed on to the MSM7227 IC for further processing.

3.2.2 GSM Transmitter

The RTR6285 transmitter outputs(HB_RF_OUT1 and LB_RF_OUT1)include on-chip output matching inductors. 50ohm output impedance is achieved by adding a series capacitor at the output pins. The capacitor value may be optimized for specific applictions and PCB characteristics based on pass-band symmetry about the band center frequency, the suggested starting value is shown in Figure1.2.2

Figure 1.2-2 GSM Transmitter matching

The RTR6285 IC is able to support GSM 850/1900 and GSM 1800/1900 mode transmitting. This design guideline shows a quad-band GSM application.

Both high-band and low band outputs are followed by resistive pads to ensure that the load

Presented to the outputs remains close to 50ohm. The low-band GSM. Tx sSAW can be eliminated because ETSI spec requires mid channels to pass RX Band noise only.

The two RTR6285/RTR6285 UMTS single-ended inputs accept its UMTS 2100/1900/1800/1700 input signal from the handset RF front-end filters. The UMTS Rx inputs are provided with onchip LNAs that amplify the signal before second-stage filters that provide differential signal to a shared downconverter. This second-stage input is configured differentially to optimize secondorder inter-modulation and common mode rejection performance. The gain of the UMTS front-end amplifier and the UMTS second-stage differential amplifier are adjustable, under MSM control, to extend the dynamic range of the receivers.

The second-stage UMTS Rx amplifiers drive the RF ports of the quadrature RF-to-baseband downconverters. The downconverted UMTS Rx baseband outputs are routed to lowpass filters having passband and stopband characteristics suitable for UMTS Rx processing. These filter circuits allow DC-offset corrections, and their differential outputs are buffered to interface with the MSM IC.

The RTR6285/RTR6285 UMTS differential input paths stay on-chip; off-chip inter-stage filtering is not required. Other than this, the architecture is similar to the single-ended inputs. The UMTS duplexer receiver output is routed to LNA circuits within the RTR6285 device. UMTS LNA circuits(one for low-band UMTS and one for high-band UMTS path) separated from all other receive functions contained within the RTR6285 IC to improve mixer LO to RF isolation- a critical parameter in the ZIF architecture. Isolation is further improved using high-reverse isolation circuits in the LNA designs

3.3.2 Transmitter

The RTR6285/RTR6285 transmit includes four transmit signal paths with five outputs (three high bands and two low bands) supporting multi-band and multi-mode GSM/GPRS/EDGE polar transmit and WCDMA/HSDPA transmit architectures. The transmit path begins with differential baseband signals (I and Q) from the MSM device.

These analog input signals are buffered, filtered by low-pass filters, amplified, and then applied to the quadrature upconverter mixers. The upconverter outputs are amplified by multiple variable gain stages that provide transmit AGC control. SSBI control from the MSM IC is used to generate the gain range control signal. The AGC outputs are then applied to the high-band and low-output driver amplifiers; the specified driver amplifier output level is achieved while supporting the GSM/EDGE and UMTS transmit standard’s requirements for GSM ORFS, carrier and image suppression, WCDMA ACLR, spurious emissions, Rx-band noise, and so forth. Again, the upconverter LO signals are generated by circuits described in Section 1.2.3. These upconverters translate the polar GMSK-modulated or 8-PSK modulated baseband PM signals and/or WCDMA baseband signals directly to the RF signals, which are filtered and fed into the GSM/EDGE polar PA and/or WCDMA PA. The WCDMA TX power is coupled back to the RTR6285/RTR6285 internal power detector input pin, PWD_DET_IN, using a coupler for power measurement.

The low-band drive amplifiers are used to transmit the polar phase modulated (PM) signal for GSM/EDGE 850/900 while the high-band driver amplifiers are for the GSM/EDGE 1800/1900.

By using the radioOne architecture, the same high-band transmit path can be used to transmit the UMTS 2100/1900/1800/1700 signal, and the low-band transmit path can be used to transmit the UMTS 800/850/900 signal, depending on the application. The envelope path is used in polar mode of operation for GSM and EDGE. Input from the MSM IC, the baseband envelope (AM) signal, is applied directly to the ramp control pin of the GSM/EDGE polar PA to modulate the power supply of the PA so that the polar modulated GSM/EDGE signal in the MSM can be recovered and transmitted.

3.4 LO Phase-locked Loop

The integrated LO generation and distribution circuits are driven by internal VCOs to support various modes to yield highly flexible quadrature LO outputs that drive all GSM/EDGE, UMTS band and GPS upconverters and downconverters; with the help of these LO generation and distribution circuits, true zero-IF architecture is employed in all GSM and UMTS band receivers and transmitters to translate the signal directly from RF-to-baseband and from baseband-to-RF.

Two fully functional fractional-N synthesizers, including VCOs and loop filters, are integrated within the RTR6285/RTR6285 IC. In addition, the RTR6285 has a third synthesizer used for GPS operation. The first synthesizer (PLL1) in the RTR6285/6280 creates the transceiver LOs that support the UMTS transmitter, and all four GSM band receivers and transmitters including: GSM 850, GSM 900, GSM 1800, and GSM 1900. The second synthesizer (PLL2) in the RTR6285/RTR6285 IC provides the LO for the UMTS primary receiver. For the RTR6285 IC only, the second synthesizer also provides the LO for the secondary UMTS receiver. The third synthesizer (PLL3), only in the RTR6285 IC, provides the LO for the GPS receiver. An external TCXO input signal is required to provide the synthesizer frequency reference to which the PLL is phase and frequency locked. The RTR6285/RTR6285 ICs integrate most of the PLL loop filter components on-chip except for three off-chip loop filter-series capacitors, which significantly reduces off-chip component requirement. With the integrated fractional-N PLL synthesizers, the RTR6285/RTR6285 ICs have the advantage of more flexible loop bandwidth control, fast lock time, and low-integrated phase error.

3.5.6 UMTS Rx SAW filter (FL1002: SAFEB2G14FA0F00)

An RF filter is located between the UMTS LNA and mixer. Insertion loss is important, but not as critical as losses before the LNA. The most important parameters of this component include:

■ Out-of-band rejection or attenuation levels, usually specified to meet these conditions:

□ Far out-of-band signals - ranging from DC up to the first band of particular concern and from the last band of particular concern to beyond three times the highest passband frequency.

□ Tx-band leakage - the transmitter channel power, although attenuated by the duplexer, still presents a cross- modulation threat in combination with Rx-band jammers. The RF filter must provide rejection of this Tx-band leakage.

□ Other frequencies of particular concern . bands known to include other wireless transmitters that may deliver significant power levels to the receiver input.

■ Phase and amplitude balance - the ZIF architecture requires well-balanced differential inputs to the RTR6285/80. This is accomplished by the RF filters which take a single-ended outputs from the ICs and provide differential outputs having nominal 180° phase separation. Phase and/or amplitude imbalance causes degraded common-mode rejection and second-order nonlinearity, so their requirements are specified jointly.

3.5.7 VCTCXO (X300 : KT-3225L-19.2MHz)

The Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) provides the reference frequency for all RFIC synthesizers as well as clock generation functions within the MSM7227 IC. The oscillator frequency is controlled by the MSM7227’s TRK_LO_ADJ pulse density modulated signal in the same manner as the transmit gain control.

The filtered PDM signal results in an analog control signal into the VCTCXO tuning port whose voltage is directly proportional to the density of the digital bit stream. The MSM device varies the pulse density to change the analog control voltage that sets the oscillator frequency – all within a feedback control loop that minimizes handset frequency drift relative to the network.

3.6 Digital Baseband(DBB/MSM7227)

3.6.1 General Description

L-04C supports UMTS-800, UMTS-2100, GSM-900, GSM -1800, GSM-1900. All receivers and the transmitter use the radio One Zero-IF architecture to eliminate intermediate frequencies, directly converting signals between RF and baseband.

A generic, high-level functional block diagram of L-04C is shown in Figure 1. One antenna collects base station g , g g gforward link signals and radiates handset reverse link signals. The antenna connects with receive and transmit paths through a SPDT( Single Port Double Throw ).

RTR6285 receive paths include four GSM/EDGE Rx signal paths that supportGSM 900, 1800, and 1900 bands, and four WCDMA Rx signal paths(two single-ended and two differential) for one UMTS low-band and three UMTS high-bands.

RTR6285 transmit includes four transmit signal paths with five outputs (three high bands and two low bands) supporting multi-band and multi-mode GSM/GPRS/EDGE polar transmit and WCDMA/HSDPA transmit architectures.

L-04C power is managed and regulated by the PM7540 Power Management IC. This versatile device integrates all wireless handset power management, general housekeeping, and user interface support functions into a single mixed signal IC. It monitors and controls the external power source and coordinates battery recharging while maintaining the handset supply voltages using low dropout, programmable regulators.

The device’s general housekeeping functions include an ADC and analog multiplexer circuit for monitoring on-chip voltage sources, charging status, and current flow, as well as user-defined off-chip variables such as temperature and battery ID. Various oscillator, clock, and counter circuits support IC and higher-level handset functions. Key parameters such as under-voltage lockout and crystal oscillator signal presence are monitored to protect against detrimental conditions.

3.7 Modem system / subsystem

3. Technical Brief

The modem subsystem includes all blocks that provide modem functionality directly (such as airlink modulation and demodulation, searching, etc) plus supporting functions (such as the modem DSP, modem AHB bus, sleep controller, interrupt controller, etc):

■ An ARM926EJ-S (ARM9) as the main modem processor.

■ A bridge to the peripheral bus that connects the modem subsystem to functions like the crypto-engine, keypad, UART, and EBI2.

■ Th AHB t AXI b id th t id t hi h d i EBI1 ll th ti li ti■ The AHB-to-AXI bridge that provides access to high-speed memory via EBI1 as well as the entire applications subsystem.

■ A modem DSP (mDSP) that controls modem hardware blocks and assists with symbol-level processing of physical layer traffic. All modem functions require mDSP support to operate.It has a limited amount of processing power and program/data storage; it must meet the sum of all modem MIPS and memory requirements (plus some overhead) for concurrent operation.

■ A 64 kB secure boot ROM containing the primary boot loader for the ARM9 processor.

■ An internal RAM (IRAM) used for inter-processor communications between the modem and applications processors. Its top eight word locations are vectors to the modem processor exception handlers.

■ A security mode control (SMC) block

Electrical fuses that are used to disable specific functionality (such as ARM debug modes

that are useful for testing but pose a potential security breach during normal operation).

Memory protection that physically prevents certain masters on the modem subsystem bus from accessingMemory protection that physically prevents certain masters on the modem subsystem bus from accessing certain memory regions. This memory protection prevents modem DM access to either IRAM or the SMC; it only allows access via the modem ARM in its supervisor mode.

The SMC block also contains other security features, such as a device ID to uniquely identify a chip.

■ An always-on modem power manager (MPM) block that controls power collapsing of the modem subsystem.

Bus interfaces provide the necessary connections to other functions:

■ The high-speed AXI bus provides access to the applications subsystem.

The modem processor and other masters can access the application subsystem, but masters within the p pp yapplication subsystem (such as the application processor) cannot access the modem subsystem for

security reasons.

■ The local AHB bus is connected to the peripheral subsystem through a bridge. The modem processor shares access to this subsystem with the applications processor. Peripherals include standard interfaces (such as USB, UART, and UIM) for external communications, and can access MSM-internal peripheral functions as well.

■ The local AHB bus also bridges to asynchronous buses to communicate with the modem hardware blocks■ The local AHB bus also bridges to asynchronous buses to communicate with the modem hardware blocks.

■ The local AHB bus is a slow-speed request/acknowledge-based bus that is used to configure the modem cores.

■ The DM host interface is used to program the data mover through the modem processor. Since these data paths have moderately high data rates (up to 3.1 Mbit/sec plus overhead), they have a direct connection to the AHB instead of going through an asynchronous bus.

3.7.3 Watchdog timerW t hd ti h t i ti

3. Technical Brief

Watchdog timer characteristics:

14-bit counter running off the sleep controller clock regime

Enables the handset to recover from unexpected hardware or software anomalies

If the microprocessor fails to periodically reset the watchdog timer the timer expires and the handset is reset

Disabled and/or reset by grounding the WDOG_EN pin or by asserting the RESIN_N pin Hardware disabling example: the ARM processor enters debug mode (indicated by the DBGACK pin of the processor

i i i f l hi h)transitioning from low to high)

Enabled by leaving the WDOG_EN pin unconnected (it has an internal pull-up) or by connecting it to VDD If temporarily disabled, it can be re-enabled by applying a system reset that clears the state of the internal signal wdog_disable When enabled, the watchdog circuit pulses the WATCHDOG_EXPIRED signal whenever its timer has expired. In NATIVE mode this signal is combined with the RESIN_N pin to generate the RESOUT_N signals and the MSM device's internal reset.

3.7.4 Sleep mode and watchdog freezeThe modem processor cannot reset the watchdog timer while in its sleep mode, but the watchdog can be frozen before entering sleep mode. To enable the freeze, the microprocessor writes a 1-0 sequence to the WDOG_FREEZE register.

3.7.5 Non-sleep modepIn non-sleep mode the processor must reset the watchdog timer at least once every 390 ms. If not, the watchdog timer expires and asserts an internal RESIN_N signal to the system. The WDOG_EXPIRED signal lasts between 53 and 106 ms (97.5 ms typical). To reset the watchdog timer, the microprocessor must write a 1-0-1 sequence to the WATCH_DOG bit of the SLEEP_CTL register.

The peripheral buses

AXI wrappers and AXI bus that connect the applications system to the modem system The applications system includes six AXI bus masters: 1) aDSP external memory master, 2) data mover, 3) HS USB, 4) MDDI, 5) VFE, and 6) MDP. The AXI bus is discussed in Section 3.3.1, but a few comments about the applications system masters are highlighted here: y g g

The data mover is a general-purpose DMA engine that supports up to 16 channels. Under control of the modem ARM, application ARM, or aDSP, it handles memory-to-memory data transfers as well as aDSP, crypto engine, NAND controller, SD controller, and USB RLP data transfers.

The data mover is used for byte alignment/packing of USB RLP data and putting it back into system memory, and then the USB DMA master transfers the byte-aligned data from system memory. The USB AHB slave interface is on the peripheral bus and is used for configuring the USB registers.

The mobile display processor is a hardware accelerator responsible for transferring an updated image from system memory to an LCD module through the MDDI host. The video front-end receives camera data directly from the parallel camera interface. It communicates with aDSP through an xDMA channel and has its own AXI bus master to access system memory.

3.8.2 PM7540

The PM7540 device (Figure 1-1) integrates all wireless handset power management, general housekeeping, and user interface support functions into a single mixed signal IC.Its versatile design is suitable for CDMA and non-CDMA handsets, and other wireless products such as PC PDAs.

The power management portion accepts power from common sources - battery, external charger, adapter, USB_VBUS, coin cell backup - and generates all the regulated voltages needed to power the appropriate handset electronics. It monitors and controls the power sources, detecting which sources are applied, verifying that they are within acceptable operational limits, and coordinates battery and coin cell recharging while maintaining the handset electronics supply voltages.

On-chip voltage regulators generate 24 programmable output voltages using a combination of switched-mode power supplies and low dropout voltage regulators, all derived from a common trimmed voltage reference. One regulator is dedicated for generating microphone bias voltages.

The device's general housekeeping functions include a 16-position analog multiplexer that has five internal connections, six hardwired external connections, and supports an additional 22 external connections. The internal connections are used to monitor on-chip functions such as the temperature sensor. The hardwired external connections access input power nodes such as VCHG, VBAT, etc. p p , ,The 22 additional external connections are made using the IC's multipurpose pins configured as analog inputs that are routed through switch circuits to create five multiplexer inputs; these are available to monitor system parameters such as temperature and battery ID.

3.8.3 Charging control

3. Technical Brief

Voltage regulation (VDD or VBAT)

The PM7540 IC provides closed-loop control of the active pass transistor (via CHG_CTL_N or USB_CTL_N) to regulate either the handset supply voltage (VDD) when not charging or the main battery final voltage (VBAT) when charging. When fast charging is disabled, the battery MOSFET is opened and the voltage regulation point is the ISNS_M pin (VDD). When fast charging is enabled, the VBAT pin is the voltage regulation point,

thereby improving the voltage precision of the fully charged battery (Li-ion battery manufacturers specify 1% accuracy).

Current regulation, monitoring, and protection

3. Technical Brief

If a sense resistor is installed across ISNS_P and ISNS_M (pins C1 and C2, respectively) the PM7540 IC constantly monitors the total handset electronics plus charging current. If the programmed current threshold is exceeded, the active pass transistor is forced to a higher resistance, disrupting VDD or VBAT regulation but protecting against excess current. The VCHG current monitor defaults to its 1 Amp current setting upon powerup, thereby minimizing the risk of a large in-rush load collapsing VDD. Similarly, the VUSB current monitor defaults to its 0.5 A current setting upon powerup.

Constant Current Charging

The PM7540 IC supports constant current charging of the main battery by closing the battery MOSFET (connecting the battery to VDD), and closed-loop controlling the active pass transistor (charger or USB). The closed-loop control regulates the total current (handset electronics plus charging current) to match the programmed value (IMAXSEL).The MSM device monitors the charging process as described earlier and continues the constant current mode until the battery reaches its target voltage. Lithium-ion batteries require further charging using constant voltage or pulsed techniques.

3.8.4 MAX17040G

3. Technical Brief

The classical coulomb-counter-based fuel gauges suffer from accuracy drift due to the accumulation of the offset error in the current-sense measurement. Although the error is often very small, the error increases over time in such systems, cannot be eliminated, and requires periodic corrections. The corrections are usually performed on a predefined SOC level near full or empty. Some other systems use the relaxed battery voltage to perform corrections. These systems determine the true SOC based on the battery voltage after a long time of no activity. Both have the same limitation: if the correction condition is not observed over time in the actual application, the error in th t i b dl I t f ll h /di h l i i d t li i t th d iftthe system is boundless. In some systems, a full charge/discharge cycle is required to eliminate the drift error.

3.9.1 High-speed memory interface (EBI1)

3. Technical Brief

EBI1 provides connectivity between multiple bus masters and their high-bandwidth memory controllers. Using the AXI (Section 3.3.1) as a standard interface between bus masters and slaves ensures high-performance data transfers. The EBI1 high-level architecture (Figure 3.9.1) includes two major functional blocks:

AXI memory controller bridge – the interface block to the AXI bus interconnect. Its primary function is to communicate with command and data transfer masters through the interconnect; it supports most non-blocking features of the AXI bus protocol. g p

SDRAM controller – the memory controller that interfaces externally with DDR SDRAM devices, and internally with the AXI memory controller bridge over a 64-bit AHB-lite interface. Its primary function is to receive and execute SDRAM memory commands from the AXI memory controller bridge.

Figure3.9.1 EBI1 high-level archiecture

EBI1 connections

All EBI1-related pins are located in the same general area of the IC package. This allows optimal routing and should minimize interference from this bus to more sensitive functions (such as analog baseband). EBI1 layout guidelines are given in Section 4.3.3.2. A single 32-bit DDR SDRAM memory device or two 16-bit devices are supported (Figure 3.9.2).

3.10.2.4 HKADC(House Keeping ADC)

3. Technical Brief

The MSM7227 IC has an on-chip 12-bit analog-to-digital converter (ADC) that is available for digitizing analog signals representing parameters such as battery voltage, temperature, and RF power levels. These parameters support handset-level housekeeping functions – various tasks that must be performed to keep the ‘house’, or handset, in order. This ADC is also used as a touch screen interface, so the acronyms TS-ADC and HK/TS-ADC are sometimes used. The HK/TS-ADC is a 12-bit successive-approximation circuit with a programmable resolution of 8, 10, or 12 bits. Its high-level block diagram is illustrated and explained in Figure 3.10.1.

3.10.13 Audio Signal Processing & Interface

3. Technical Brief

Audio signal processing is divided uplink path and downlink path.The uplink path amplifies the audio signal from MIC and converts this analog signal to digital signal and then transmits it to DBB Chip (MSM7227).This transmitted signal is reformed to fit in GSM & WCDMA frame format and delivered to RF Chipset. The downlink path amplifies the signal from DBB chip (MSM7227) and outputs it to receiver (or speaker).

The receive path can be directed to either one of two earphone amplifiers or the auxiliary output.The outputs earphone1 (EAR1OP, EAR1ON) and auxiliary out (AUXOP, AUXON) are differential outputs. p p ( , ) y ( , ) pEarphone2 (EAR2/EAR3) is a single-ended output stage designed to drive a headset speaker.

The microphone interface consists of two differential microphone inputs, one differential auxiliary input and a two-stage audio amplifier.
