3.1.3 GSM System DescriptionThe E-GOLDvoice is suited for mobile stations operating in the GSM850/900/1800/1900 bands.In the receiver path the antenna input signal is converted to the baseband, filtered, and then amplifiedto target level by the RF transceiver chipset.Two A-to-D converters generate two 6.5 Mbit/s data streams. The decimation and narrowband channelfiltering is done by a digital baseband filter in each path.

The DSP performs:1. The GMSK equalization of the received baseband signal (SAIC support available)2. Viterbi channel decoding supported by an hardware accelerator.

The recovered digital speech data is fed into the speech decoder.The E-GOLDvoice supports fullrate, halfrate, enhanced fullrate and adaptive multirate speech CODECalgorithms.The generated voice signal passes through a digital voiceband filter. The resulting 4 Mbit/s datastream is D-to-A converted by a multi-bit-oversampling converter, postfiltered, and then amplified by aprogrammable gain stage.The output buffer can drive a handset ear-piece or an external audio amplifier, an additional outputdriver for external loud speaker is implemented.In the transmit direction the differential microphone signal is fed into a programmable gain amplifier.The prefiltered and A-to-D converted voice signal forms a 2 Mbit/s data stream. The oversampledvoice signal passes a digital decimation filter.The E-GOLDvoice performs speech and channel encoding (including voice activity detection (VAD)and discontinuous transmission (DTX)) and digital GMSK modulation.In the RF transceiver part, the baseband signal modulates the RF carrier at the desired frequency inthe 850 MHz, 900 MHz, 1.8 GHz, and 1.9 GHz bands using an I/Q modulator. The E-GOLDvoicesupports dual band applications.Finally, an RF power module amplifies the RF transmit signal at the required power level. Usingsoftware, the E-GOLDvoice controls the gain of the power amplifier by predefined ramping curves (16words, 11 bits).For baseband operation, the E-GOLDvoice supports:

• Making or receiving a voice call• Sending or receiving an SMS.

3.1.4 PMU DetailsThe E-GOLDvoice includes battery charger support (various sensor connections for temperature,battery technology, voltage, etc.) and a ringer buffer.E-GOLDvoice avoids the need for an external power management component because its internalpower management unit contains:

• Voltage regulators for the On-chip and Off-chip functional blocks• Charger circuitry for NiCd, NiMh and LiIon cells.

3.1.5 Bus ConceptThe E-GOLDvoice has two cores (a microcontroller and a DSP), each with its own bus.There is an interconnection between the TEAKlite bus and the C166S X-Bus.

3.1.6 C166S BusesThe C166S is connected to three buses:

1. Local Memory (LM) bus2. X-Bus3. PD-Bus.

3.1.7 TEAKLite BusThe TEAKlite is connected to the TEAKlite bus.

3.1.8 Bus InterconnectionsThe interconnection between the X-Bus and the TEAKlite Bus uses:

• Multicore Synchronization• Shared Memory.

3.1.9 Clock ConceptThe E-GOLDvoice has a flexible clock control.

3.1.10 Interrupt ConceptThe C166 MCU carries out the E-GOLDvoice interrupt system.

3.1.11 Debug ConceptThe E-GOLDvoice includes a multi-core debug. The C166 and TEAKlite cores can be debugged inparallel with:

• A single JTAG port (that is, on a single host)• Mutual breakpoint control.

Page 19: Lg Kg270, Mg160 Service Manual

3.1.12 C166 Debug ConceptThe debugging of the C166 uses the OCDS and the Cerberus.

3.1.13 TEAKLite Debug ConceptTEAKlite debugging uses the OCEM and the SEIB.

3.1.14 Power ManagementThe E-GOLDvoice provides the power management unit (PMU) for the complete mobile phoneapplication. The integrated PMU is directly connected to the battery and provides a set of linearvoltage regulators (LDO’s).These LDO’s generate all required supply voltages and currents needed in a low feature mobilephone. A charger control circuit charges NiCd, NiMH and LiIon batteries.The charger control supports hardware controlled pre-charging and software controlled charging. Itoffers a wide charger voltage range, making halfwave/full-wave charging with cheap transformerspossible.White/blue backlight generation is supported with a special driver for very a low external parts count.Power consumption during operation phases is minimized due to flexible clock switching In theStandby Mode most parts of the device are switched off, only a small part is running at 32kHz and thecontroller RAM is switched to a power saving mode. The TEAKLite ROM can be switched off duringStandby via SW.

3.1.15 On-Chip Security ConceptSecure boot is based on a public/private key approach. Flash images that are not signed with theprivate key during phone manufacture cannot be loaded.Verification of the Flash code is done with the public key. The public key as well as hash and verifyalgorithms are stored in the ROM, which ensures a hardware secured boot procedure.

The following security features are supported:• Prevention of illegal Flash programming• Flash programming makes use of the E-GOLDvoice ID for personalization checks with IMEI and

SIM-lock protection

3. TECHNICAL BRIEF

- 20 -

Page 20: Lg Kg270, Mg160 Service Manual

3. TECHNICAL BRIEF

- 21 -

The security features use the following mechanism:• Boot ROM flow:

- Controls the boot transition to external flash- Controls the flash update

• Flash tied to the individual chip via an ID using e-fuses, that is, each E-GOLDvoice chip has itsown fused ID.

Further details on the E-GOLDvoice security concept are not publicly documented.

3.1.16 Asynchronous Operation Mode ConceptThe E-GOLDvoice can operate in either:

• The traditional synchronous mode with the 26MHz system clock synchronized on the base station• A special asynchronous mode (XO concept).

In the asynchronous mode the 26MHz clock input is not synchronized with the base station; theresidual frequency offset is compensated in the digital signal processing domain. This processingincludes frequency and timing compensation of the baseband and voiceband signals.

Page 21: Lg Kg270, Mg160 Service Manual

3.2 Power Amplifier Module (SKY77318)

The SKY77318 Power Amplifier Module (PAM) is designed in a low profile (1.2 mm), compact formfactor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation.The PAM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation.

The module consists of separate GSM PA and DCS1800/PCS1900 PA blocks, impedance-matchingcircuitry for 50 Ω input and output impedances and a Power Amplifier Control (PAC) block with aninternal current-sense resistor. The custom BiCMOS integrated circuit provides the internal PACfunction and interface circuitry.Fabricated onto a single Gallium Arsenide (GaAs) die, one Heterojunction Bipolar Transistor (HBT) PAblock supports the GSM bands and the other supports the DCS1800 and PCS1900 bands. Both PAblocks share common power supply pins to distribute current.

The GaAs die, the Silicon (Si) die, and the passive components are mounted on a multi-layer laminatesubstrate. The assembly is encapsulated with plastic overmold.

Page 22: Lg Kg270, Mg160 Service Manual

3. TECHNICAL BRIEF

- 23 -

RF input and output ports of the SKY77318 are internally matched to a 50 Ω load to reduce thenumber of external components for a quad-band design. Extremely low leakage current (2.5 µA,typical) of the dual PA module maximizes handset standby time. The SKY77318 also containsbandselect switching circuitry to select GSM (logic 0) or DCS/PCS (logic 1) as determined from theBand Select (BS) signal.

In Figure 1 below, the BS pin selects the PA output (DCS/PCS_OUT orGSM_OUT) and the AnalogPower Control (VAPC) controls the level of output power.

The VBATT pin connects to an internal current-sense resistor and interfaces to an integrated poweramplifier control (iPAC) function, which is insensitive to variations in temperature, power supply,process, and input power.The ENABLE input allows initial turn-on of PAM circuitry to minimize battery drain.

3.3 26 MHz Clock (DCXO)

DCXO (Digitally Controlled Crystal Oscillator) and VCTCXO (Voltage Controlled TemperatureCompensated Crystal Oscillator) are two different techniques used To maintain the mobile’s referenceoscillator’s accuracy over time. The reference oscillator’s accuracy over time will vary due to initialcrystal frequency offset, temperature drift and aging.These static and dynamic frequency variations have to be compensated, otherwise the mobile wouldbe in danger of losing connection to the network.The technique used to perform the frequency compensation is generally termed Automatic FrequencyControl (AFC).To summarize the operation of DCXO, GSM Baseband processor will calculate the AFC compensation(which is continuously updated) required based on the measured frequency error. Then the requiredAFC compensation is sent to the LUXO (Lineari-Zation Unit of Crystal Oscillator), which in turnscontrol the DCXO core and generates The 26MHz system clock.

3.4 RTC(32.768KHz Crystal)

The integrated Real Time Clock (RTC) is able to provide programmable alarm functions and externalinterrupts. Due to its extreme low power consumption the RTC can be supplied from a small backupbattery. This allows the generation of external interrupts, even when the main PMB7880 supplyvoltage is switched off. For this purpose the RTC is powered by own voltage supply pins VDD_RTCand VSS_RTC.The RTC shall be driven by a 32.768 kHz (32k) clock which needs to be applied via the PMB7880F32K and OSC32K pins. The clock can be fed from either an external clock source or use the on chip32 KHz oscillator module.The low clock frequency and the optimized low power design give the possibility to run the chip with aminimum of power dissipation. For example, for this specific application the 26 MHz referenceoscillator can be switched off during system standby and a lowpower time reference can be kept whenthe 32k clock is provided to the RTC.The RTC consists of an PMB7880 specific RTC shell, containing the RTC macro, as well as the 32kHz oscillator, as described in the following sections. The module RTC Shell solely performs leveltranslation of the 32KHz clock to the VDD_LD1 power supply domain, and is not functionallyassociated with the RTC.

The AAT3157 is a low noise, constant frequency charge pump DC/DC converter that uses a trimodeload switch (1X), fractional (1.5X), and doubling (2X) conversion to maximize efficiency for white LEDapplications. The AAT3157 is capable of driving up to three channels of LEDs at 20mA per channelfrom a 2.7V to 5.5V input.The current sinks may be operated individually or in parallel for driving higher current LEDs. A lowexternal parts count (two 1µF flying capacitors and two small 1µF capacitors at VIN and VOUT) makethis part ideally suited for small, battery-powered applications. AnalogicTech's S2Cwire™ (SimpleSerial Control™) serial digital input is used to enable, disable, and set current for each LED with 16settings down to 50µA.The low-current mode supply current can be as low as 50µA to save power.

3.9 RF Interface

E-GOLDvoice features a fully integrated constant-gain direct conversion receiver, i.e. there is nointerstage filter needed and the baseband level at the analogue IQinterface follows directly the RFinput level. Depending on the baseband ADC dynamic range, single- or multiple-step gain switchingschemes are possible.An integrated, selfaligning, low-pass filter ensures the receivers to function under blocking andreference interference conditions and avoids aliasing by baseband sampling. An automatic DC-offsetcompensation is implemented and can be switched depending on the gain setting.

The digital transmitter architecture is based on a fractional-N sigma-delta synthesizer for constantenvelope GMSK modulation. This configuration allows a very low power design with a reducedexternal component count.The modulation is transferred between baseband- and RF-part of the PMB7880 via a digital interfacesignal into the digital modulator.The following Gaussian filter shapes the digital data stream for the GMSK modulation. Additionally apre-distortion filter compensates the attenuation of the PLL transfer function resulting in a very lowdistortion at the transmit output.The filtered digital data stream is scaled appropriately and added to the channel word. This sum is fedinto the MASH modulator. The output of the MASH modulator is a sequence of integer divider valuesrepresenting the high resolution fractional input signal. This sequence controls the MMD (multimodulus divider) at a sample rate of 26MHz. Thus a tightly controlled frequency modulation of theVCO is achieved.

3.10 Audio Interface

The audio front-end of E-GOLDvoice offers the digital and analog circuit blocks for both receive andtransmit audio operation and ringing. It features a high-quality, digital-to-analog path with amplifyingstages for connecting acoustic transducers to the E-GOLDvoice. In the transmit direction the supplyvoltage generation for microphones, low-noise amplifier and analog to digital conversion are integratedon the E-GOLDvoice.For E-GOLDvoice the EPp1/EPn1 driver are used as differntial Earpiece-Driver, EPPa1 is used assingle-ended Headset-Driver.

The audio front-end itself can be considered to be organized in three sub-blocks:• Interface to processor cores (TEAKlite and - indirectly - C166S)• Digital filters• Analog part.

The interface to the processor cores consists of a direct physical connection to the TEAKlite DSP busand a set of firmware commands to handle communication between the C166S and the audio front-end which serves as the interface peripheral for audio algorithms running on the DSP or the controller.The audio front-end Generates interrupts on certain occasions, for example, when exchange of data isrequested. The core interface part of the audio front-end also contains the control and status registerswhich are used to set up certain operation modes of the peripheral.The section next to the core interface contains the digital filters for interpolation and decimation of theaudio signals being received and transmitted. The data path for the receive direction can be set up toprocess sampling rates between 8kHz and 48kHz.The interpolation filters for the respective sampling rates are implemented in a dedi-cated hardwareblock and are automatically selected to suite the chosen sampling rate.Low-pass interpolation filtering, which produces an unsigned 16-bit data stream with a sampling rate of4 MHz, is performed digitally. D-to-A conversion, postfiltering, and final amplification are performed onthe analog part. The amplifier buffer for voiceband receive does also support ringer functionality. Theringer functionality is activated by Setting bits RINGSELPN or RINGSELPA in the voiceband part ofthe analog control register.In transmit direction, amplification, prefiltering and A-to-D conversion (analog ∑∆ modulation) areperformed on the analog part. The resulting 2-Mbit/s data stream is filtered by a digital low-passdecimation filter for further processing by DSP firmware.Two sampling rates, 8kHz and 16kHz, are supported.The analog section contains all the necessary analog functional blocks including microphone supplygeneration, output and input amplifiers and analog filtering.

3.14 Power Block Interface

The E-GOLDvoice integrated power management unit (PMU) supports direct connection to battery(DCB). That means all supply voltages needed are generated on-chip with integrated linear voltageregulators. The input of these linear voltage regulators is the battery voltage. The external memory andSIM card supply is provided by the on-chip voltage regulators. Table 144 is an overview of the internalgenerated supply voltages.The integrated power management also provides the control state machine for system start up,including start up with discharged batteries, trickle charging and system reset control. After systemstart up several methods are implemented for active and idle power saving.

LDO output voltage selection• LD1, LIO, LSIM, LBUF output voltage programmable by software.• LMEM output voltage is selectable by pin configuration upon startup.

Active and idle power saving options:• The flexible clock switching options allow minimizing the power consumption during the operation

phases of the E-GOLDvoice.• Current consumption during the standby mode is minimized by reducing the clock to 32 kHz andswitching it off for most of the device. In addition, the power supply for the TEAKLite ROM isswitched off and the controller RAM is switched to a power saving mode.

Start-up and Reset Control State Machine Features• Power up upon battery insertion, push button, alarm, charger connection.• Detection of battery exchange or re-insertion.• Complete start-up sequence management.• System turn-on, system turn-off operation management including emergency (under-voltage) and

programmed shutdown functions.• Internal reset of the baseband, including silent reset.• Tri-state function of the baseband module.• Standby mode controlled by VCXO_EN provided by SCCU module.

3. TECHNICAL BRIEF

- 43 -

3.15.1 FM TunnerThe Si4702 patented digital low-IF architecture reduces external components and eliminates the needfor factory adjustments. The receive (RX) section integrates a low noise amplifier (LNA) supporting theworldwide FM broadcast band (76 to 108 MHz). An automatic gain control (AGC) circuit controls thegain of the LNA to optimize sensitivity and rejection of strong interferers.

For two-wire operation, a transfer begins with the START condition. The control word is latchedinternally on rising SCLK edges and is eight bits in length, comprised of a seven bit device addressequal to 0010000b and a read/write bit (write = 0 and read = 1). The device acknowledges the addressby setting SDIO low on the next falling SCLK edge. For write operations, the device acknowledge Isfollowed by an eight bit data word latched internally on rising edges of SCLK.The device always acknowledges the data by setting SDIO low on the next falling SCLK edge. Aninternal address counter automatically increments to allow continuous data byte writes, starting withthe upper byte of register 02h, followed by the lower byte of register 02h, and onward until the lowerbyte of the last register is reached. The internal address counter then automatically wraps around tothe upper byte of register 00h and proceeds from there until continuous writes cease. Data transferceases with the STOP command. After every STOP Command, The internal address counter is reset.For read operations, the device acknowledge is followed by an eight bit data word shifted out on fallingSCLK edges. An internal address counter automatically increments to allow continuous data bytereads, starting with the upper byte of register 0Ah, followed by the lower byte of register 0Ah, andonward until the lower byte of the last register is reached. The internal address counter thenautomatically wraps around to the upper byte of register 00h and proceeds from there until continuousreads cease. After each byte of data is read, the controller IC should return an acknowledge if anadditional byte of data will be requested. Data transfer ceases with the STOP command. After everySTOP command, the internal address counter is reset.

3.15.2 Headphone AmplifierThe MAX4411 fixed-gain, stereo headphone driver features Maxim’s patented DirectDrive architecture,eliminating the large output-coupling capacitors required By conventional single-supply headphonedrivers. The device consists of two 80mW Class AB headphone drivers, internal feedback network(fixed -1.5V/V gain), undervoltage lockout (UVLO)/shutdown control, charge pump, andcomprehensive click-and-pop suppression circuitry.
