3. TECHNICAL BRIEF
3. TECHNICAL BRIEF
3.1 Power Amplifier (SKY77318, U500)
The SKY77318 Power Amplifier Module (PAM) is designed in a low profile (1.2 mm), compact form factor 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 GSM850/900 PA and DCS1800/PCS1900 PA blocks, impedancematching circuitry for 50 Ω input and output impedances, and a Power Amplifier Control
(PAC) block with an internal current-sense resistor. The custom BiCMOS integrated circuit provides the internal PAC function and interface circuitry. Fabricated onto a single Gallium Arsenide (GaAs) die, one Heterojunction Bipolar Transistor (HBT) PA block supports the GSM850/900 bands and the other supports the DCS1800 and PCS1900 bands. Both PA blocks 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 laminate substrate. The assembly is encapsulated with plastic overmold. RF input and output ports of the SKY77318 are internally matched to a 50 Ω load to reduce the number 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 contains band-select switching circuitry to select GSM (logic 0) or DCS/PCS (logic 1) as determined from the Band Select (BS) signal. In
Figure 1 below, the BS pin selects the PA output (DCS/PCS OUT or GSM850/900 OUT) and the
Analog Power Control (VAPC) controls the level of output power. The VBATT pin connects to an internal current-sense resistor and interfaces to an integrated power amplifier control (iPAC TM ) 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. Figure 1. Functional

3. TECHNICAL BRIEF
3.2 Transceiver (AD6548, U501)
The AD6548/9 provides a highly integrated direct conversion radio solution that combines, on a single chip, all radio and power management functions necessary to build the most com-pact GSM radio solution possible. The only external components required for a complete radio design are the Rx SAWs, PA, Switchplexer and a few passives enabling an extremely small cost effective GSM Radio solution. The AD6548/9 uses the industry proven direct conversion re-ceiver architecture of the OthelloTM family. For Quad band appli-cations the front end features four fully integrated programmable gain differential LNAs. The RF is then downconverted by quad-rature mixers and then fed to the baseband programmable-gain amplifiers and active filters for channel selection. The
Receiver output pins can be directly connected to the baseband analog processor. The Receive path features automatic calibration and tracking to remove DC offsets. The transmitter features a translation-loop architecture for di-rectly modulating baseband signals onto the integrated TX VCO.
The translation-loop modulator and TX VCO are extremely low noise removing the need for external SAW filters prior to the PA. The AD6548/9 uses a single integrated LO VCO for both the receive and the transmit circuits. The synthesizer lock times are optimized for GPRS applications up to and including class 12.
AD6548 incorporates a complete reference crystal calibration system. This allows the external VCTCXO to be replaced with a low cost crystal. No other external components are required. The AD6548 uses the traditional
VCTCXO reference source. The AD6548/9 also contains on-chip low dropout voltage regula-tors (LDOs) to deliver regulated supply voltages to the functions on chip, with a battery input voltage of between 2.9V and 5.5V.
Comprehensive power down options are included to minimize power consumption in normal use. A standard 3 wire serial interface is used to program the IC. The interface features low-voltage digital interface buffers compatible with logic levels from 1.6V to 2.9V.

3.9 Keypad Switches and Scanning
The key switches are metal domes, which make contact between two concentric pads on the keypad layer of the PCB when pressed. There are 15 switches (Normal Key 12EA, Volume up down side key, camera side key), connected in a matrix of 5 rows by 3 columns, as shown in Figure 3-11, which is connected independently. Functions, the row and column lines of the keypad are connected to ports of
AD6721. The columns are outputs, while the rows are inputs and have pull-up resistors built in. When a key is pressed, the corresponding row and column are connected together, causing the row input to go low and generate an interrupt. The columns/rows are then scanned by AD6721 to identify the pressed key.

3.10 Microphone
The microphone is placed to the Rear cover and contacted to main PCB. The audio signal is passed to
VINNORP and VINNORN pins of AD6721. The voltage supply VMIC is output from AD6721, and is a biased voltage for the VINNORP. The VINNORP and VINNORN signals are then A/D converted by the voiceband ADC part of AD6721.The digitized speech (PCM 8KHz ,16KHz) is then passed to the DSP section of AD6721 for processing (coding, interleaving etc).

• Baseband Transmit section
This Section is designed to support GMSK and 8-PSK for both single-slot and multislot applications.
And it is generated in-phase and quadrature BB modulated GMSK & 8-PSK signals. The transmit channel consists of a digital GMSK & 8-PSK modulator, a matched pair of 10-bit DACs and a matched pair of reconstruction filter. The GMSK modulator which is used for GSM applications. And the 8-PSK modulator which is used for EDGE applications.
• Baseband Receive section
This section is designed to support GMSK and 8-PSK applications. And is consists of two identical
ADC channels that process baseband in-phase and quardrature input signals. Each channel consists of a coarse switched capacitor input filter, followed by a highorder sigma-delta modulator and a lowpass digital filter.
• Auxiliary section
The AD6852 Auxiliary Section includes a Phase Locked Loop, Automatic Frequency Control (AFC)
DAC, voltage reference buffers, an Auxiliary ADC, and light controllers.
♦
Low-Noise Voltage Reference and Voltage Reference Buffers
The AD6852 provides a low-noise voltage reference and several voltage buffers which produce isolated references. The REF voltage is directly used as a reference for analog voltage regulators.
The REF voltage is used along with internal reference buffers to provide references for all of the
AD6852 digital-to-analog and analog to-digital converters. The REFBB voltage is used as a reference for the baseband transmit and baseband receive section ADCs and DACs. The
REFOUT voltage is provided for use with external devices. For example, the REFOUT voltage may be applied to measure crystal temperature using a thermistor. The REFCHG voltage is also provided for use with external devices. For example, the REFCHG voltage may be applied to measure battery temperature using a thermistor. The AD6852 provides automatic activation of the
REFBB buffer. When the baseband transmit path or baseband receive path are active, the REFBB buffer is active.
♦ Automatic Frequency Control (AFC) DAC
The AD6852 AFC DAC is a 13-bit Sigma-Delta DAC that intrinsically does not exhibit differential nonlinearity. Input data stream is sent into converted via Control Serial Port. AFCDACM (0x16) and
AFCDACL (0x17 ) registers allow to fetch in bits 15-6 and 9-0 respectively. In typical applications, the AFC DAC must often remain active while all other converters are idle. To minimize system supply current in this condition, the AFC DAC may operate with the master clock idle. The AFC
DAC uses a low-power internal oscillator to maintain a stable output voltage based on the last digital input value.

3. TECHNICAL BRIEF
♦ Temperature Sensing System
The AD6852 includes voltage reference buffers and Auxiliary ADC inputs for measuring the temperature of the system oscillator crystal (to compensate for temperature variations) and the battery temperature (for charging applications). Each of these external temperatures may be measured using an external thermistor in series with an external resistor. The temperature ranges are based on the requirements of 3GPP TS 51.010-1 version 5.2.1 Release 5 (2003-02), Annex 1
(normative): Reference test methods, A1.2: Normal and extreme Test Conditions (TC). The more narrow temperature span, + 15 ˚C to + 80 ˚C, provides for a difference between operating temperature and ambient temperature under normal test conditions of up to 45 ˚C. There are two temperature measurement channels available, TEMP1 and TEMP2. TEMP1 is chosen if the
BatTempCh bit in the AuxControl2 register (0x14) is set low. TEMP2 is chosen if the bit is high.
♦ Auxiliary Section Control Registers
The AD6852 Auxiliary ADC digital interface provides a method for making a single Auxiliary ADC measurement and a method for updating the battery condition. If a single Auxiliary ADC measurement is desired, the Auxiliary ADC channel can be selected and the Auxiliary ADC enabled. After the conversion is complete the interrupt is asserted. The result can be read from the
AuxADCM (0x18 ) and AuxADCL (0x19 ) registers. If the battery condition update is desired, the
BatCondition bit in the AuxControl2 register should be set. The battery condition is determined by reading the BatCondM (0x1A ) and BatCondL (0x1B ) registers four times.
♦
Light Controllers
The AD6852 Auxiliary Section provides three independent PWM light controllers. The PWM output controllers regulate the average current through active lights.
Minimum Output Frequency fMCLK / 262144 Hz
Maximum Output Frequency fMCLK / 256 Hz
The output frequencies of the LIGHTx PWM output controllers are set by the
Light12Period (0x2F ) and Light3Period (0x31 ) control registers.
With fMCLK = 13 MHz, frequencies ranging from 50.781 kHz to 49.591 Hz may be specified.
fLIGHT1 = ( fMCLK / 256 ) / ( Light12Period[9:0] + 1 ) fLIGHT2 = ( fMCLK / 256 ) / ( Light12Period[9:0] + 1 ) fLIGHT3 = ( fMCLK / 256 ) / ( Light3Period[9:0] + 1 )

• Audio section
This section supports communications and personal audio applications. The audio section provides an audio codec with two digital-to-analog converts and an analog-todigital converter, a ring tone volume controller, a microphone interface, and analog input and output channels.
♦ Audio Codec
The AD6852 audio codec supports communications applications with digital sample rates of 8 kHz or 16kHz. DAC 1 is used for receiving speech. An ADC is used for sending speech.
The AD6852 audio codec supports personal audio applications with digital sample rates of 8 kHz,
11.025kHz, 12 kHz, 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, or 48 kHz. DAC 1 and DAC 2 are used for monophonic audio. The channels are common in the digital section. DAC 1 and DAC
2 are used together for stereo audio, with DAC 1 decoding the left-channel digital input and DAC 2 decoding the rightchannel digital input. Audio codec operating modes can be controlled by writing
5 bit codes in the AudMode field of the AudControl1 register and in the AudMode field of the
AudControl4 register. AudControl1 programs the sampling rate and stereo or monophonic operating mode for PCM audio samples input via the ASPORT.
AudControl4 programs the sampling rate and stereo or monophonic operating mode for PCM audio samples input via the MSPORT. Receive audio signal from MIC. LG-G832 is used differential configuration. Send audio signal to Receiver. LG-G832 is used differential configuration.

3. TECHNICAL BRIEF
♦ Voltage Regulators
- DBB Core Voltage Supply
The VCORE regulator is designed to be used as the core power supply for the DBB. With the
Hermes DBB its use is always appropriate. If the AD6721 VAPPCFG terminal is pulled up to the main battery the pass device supply VAPP operates as a Core supply and can be used for this purpose. Using VAPP as the core supply in this manner has three advantages. This mode frees up the VCORE regulator for other applications such as use as a 1.8V memory supply. VAPP is dynamically scalable that is its voltage can be changed as DBB clock frequencies are scaled.
And use of VAPP off loads power dissipation from the ABB to the pass device. This can be important in power budgeting (see the Power Dissipation Budgeting Procedure section below).
- Serial Peripheral Supply
The nominal 2.8V VEXT regulator is meant to be a power supply used by various peripheral devices in a handset. In the example shown in Figure 4 VEXT is a digital I/O supply for the displays and the camera, a supply for the FM radio IC, and an I/O supply for the IrDA transceiver.
PSRAM, SRAM, NAND/NOR Flash Memory, SD/MMC, and DBB Memory Bus Supplies In the example shown in Figure 4 the stack memory device uses the VMEM (at 2.8V) supply, VCORE and the pass device VAPP supply. The SD or MMC card uses the VEXT supply. In the example
VAPP is programmed to be 1.8V nominal. Stack memory devices will have an SRAM, or PSRAM and one or two types of Flash memory, NAND flash and/or NOR flash. Stack memory devices will have a separate supply rail for each memory chip in the stack. The VCORE, VMEM and VAPP pass device regulator are all appropriate choices for use as memory supplies.
DBB USB Transceiver Supply
The VUSB regulator supplies power to the USB transceiver in the DBB. Its input is the USB
VBUS line.
- Camera Supplies
In the example in Figure 4 the camera module has three supply rails. VGP set to 2.8V is the camera analog supply used to power the camera’s sensor. VEXT is used as the I/O supply. And
VAPP set to 1.8V is the camera digital supply. The camera module used in the example is a type that does both image sensing and image processing. VGP and VAPP are both programmable voltage supplies.

3. TECHNICAL BRIEF
- SIM Card Supply
The SIM card supply is the VSIM regulator. This regulator has been designed to meet the power supply standards established for SIM Cards.
- Microphone Power
The VMIC regulator is designed to act as a phantom bias supply for electret microphones used in handsets and headset accessories. TDMA noise immunity is a design feature of the VMIC regulator. VMIC features low output noise in the voice audio band and should be the only supply used for microphone bias.
- Radio Reference Oscillator Power
The VRF regulator is a low out put noise supply with a specified TDMA ripple rejection. It is designed to be the power supply for the system reference oscillator in the radio subsystem.
- DBB Real Time Clock Power
The VRTC regulator is included for the purpose of powering the DBB time of day clock (RTC). A recommended backup circuit for use with VRTC is described in the section below.
- ABB Analog Supply
The ABB analog circuit supply VABB is for use by the AD6721 ABB only. The sole connection to the VABB terminal should be the recommended bypass capacitor. The VABB regulator may not be utilized by any devices other than the ABB IC.

8. TA /USB Charging (ISL6299)
The ISL6299 is a fully integrated low-cost single-cell Li-ion or Li-polymer battery charger. The charger accepts two power inputs, normally one from a USB (Universal Serial Bus) port and the other from a desktop cradle. The ISL6299 is an ideal charger for smart handheld devices that need to communicate with a personal computer via USB.
The ISL6299 features 28V and 7V maximum voltages for the cradle and the USB inputs respectively.
Due to the 28V rating for the cradle input, low-cost, large output tolerance adapters can be used safely. When both inputs are powered, the cradle input is used to charge the battery. The charge current is programmable for the cradle input with a small resistor. The end-of-charge current for the cradle input is also programmable by another external resistor. The charger incorporates
Thermaguard TM which protects the IC against over temperature. If the die temperature rises above a typical value of 100C, a thermal foldback function reduces the charge current automatically to prevent further temperature rise. The charger preconditions the battery with low current when the battery voltage is below 2.6V. The charger has two indication pins. The PPR (power present) pin outputs an open-drain logic LOW when either the cradle or the USB input power is attached. The CHG (charge) pin is also an open-drain output that indicates a logic LOW when the charge current is above a minimum current level. When the charge current is below the minimum current, the CHG pin indicates a logic HIGH signal and the status is latched. The latch will be reset at one of these events: (1) the part is disabled and re-enabled; (2) the selected input source has been removed and re-applied, (3) The USBON turns LOW, or (4) The BAT pin voltage falls below the CV mode threshold.
