3. TECHNICAL BRIEF



Power On Reset Generator

The power-on reset signals (RESET1P8 and RESET2P8) are asserted based on the VCORE (if VAPPCFG = 0), VMEM, VEXT, and VPLL regulators. RESET1P8 and RESET2P8 are low when reset is enabled and high when reset is disabled. When the outputs of all four regulators reach their corresponding threshold voltages, reset will be disabled after a nominal reset period of 130ms.The outputs of all four regulators must remain at or above their corresponding threshold voltages for the duration of the reset period for reset to be disabled (pulled high). The nominal 130ms reset period is restarted whenever all four regulators reach their threshold voltages. The nominal reset period of 130ms can be extended by connecting an external capacitor to CRST. This capacitor is charged using a small current when reset is enabled. Once the capacitor reaches the threshold, reset is disabled.Reset will be enabled immediately if any one of the four regulators falls below their corresponding threshold voltages. In addition, reset will be enabled if VBAT falls below VRTC. The PWREN signal is the logical AND of all the state controls that enable or disable many of the regulators on the chip. If the regulators enabled by PWREN are disabled by PMT state controls described below then PWREN must go low. When PWREN goes low reset will be immediately enabled causing RESET1P8 and RESET2P8 to be pulled low.When reset is enabled, both RESET1P8 and RESET2P8 are actively pulled low. CRST is also actively pulled low when reset is enabled.

VABB Regulator Enable/Disable Logic Operation

The VABB regulator powers many on-chip analog circuits on the ABB. The VCXOEN signal, the VABBEn bit in the LDOControl1 Bit Positions ( Addr 0x35) register, and the AFCDACMode and AFCDACOn bits in the AuxControl1 Bit Positions ( Addr 0x13) register all particpate in controlling the VABB enable/disable. When the ABB power management system transitions from Off state, DDLO state, UVLO state, or Thermal Shutdown State to Power Key Activation, Charger Activation, USB Charger Activation, or Active State VABB will be enabled. During these state transitions ABBEn = 0 and AFCDACMode = 0, VRF is enabled.Once the ABB power management system is in Power Key Activation, Charger Activation, USB Charger Activation, Active-Standby or Active State the VABB regulator enable/disable is controlled by the information written to the VABBEn and AFCDACMode register bits by system software.



3. TECHNICAL BRIEF



Digital Baseband Core (VCORE)

The Digital Baseband Core regulator supplies the digital baseband processor (DBB) core.The voltage on VCORE is selectable using the VCOREControl register. The VCOREActive code selects the voltage on VCORE in high power mode and the VCOREStandby code selects the voltage on VCORE in low-power mode.

DBB Interface (VINT)

The DBB interface regulator supplies the DBB/ABB digital interfaces. The output voltage of the VINT regulator is nominal 1.8V.

Memory (VMEM)

The VMEM regulator supplies the external memory(s) and the interface to the external memory on the digital baseband processor. The output voltage of the Memory Interface regulator can be selected as 1.8V nominal or 2.8V nominal using the VMEMSEL terminal.

External Interface (VEXT)

The External Interface regulator supplies the Radio digital interface and the high voltage (>1.8V) interface between the digital baseband processor and various peripherals, such as the LED indicators and the LCD display.

SIM Interface (VSIM)

AD6725 is designed to support 3.0 V and 1.8 V SIMs exclusively (i.e. no 5 V SIMs). The SIM Interface regulator supplies the SIM interface circuitry on the digital processor and the SIM card. By default the SIM Interface regulator output is 2.85 V, which can be decreased to 1.8 V if a 1.8 V SIM is detected.

Real-Time Clock (VRTC)

The Real-Time Clock regulator supplies the Real-Time Clock module. The Real-Time Clock regulator is optimized for low ground current.




3. TECHNICAL BRIEF



Baseband Analog (VABB)

The Baseband Analog regulator supplies the analog portions of the AD6725. Operation of the VABB regulator is controlled by the VABBEn bit in the LDOControl1 register. If VABBEn = 0, the VABB regultor will be disabled unless the AFCDAC is enabled or VCXOEN = 1. If VABBEn = 1 (the default state) VABB is enabled along with VCORE, VMEM, and VEXT. The Baseband Analog regulator is optimized for high ripple rejection and low noise. The output of the Baseband Analog regulator should not be used as a supply for any external components.

Microphone (VMIC)

The Microphone regulator supplies the microphone interface circuitry. The Microphone regulator is optimized for extremely high ripple rejection up to 217 Hz and low noise.

VRF (VRF)

The VCXO regulator supplies the voltage controlled crystal oscillator (VCXO). The VCXO regulator is optimized for high ripple rejection and low noise.

USB Interface (VUSB)

The VUSB regulator supplies the USB transceiver located in the DBB. Digital Baseband PLL (VPLL) The VPLL regulator supplies the phase locked loop on the digital baseband (DBB).

General Purpose Regulator (VGP)

The General Purpose regulator is intended primarily to serve as a supply rail for camera modules. Its voltage is programmable by setting VGPSel[3:0] in theLDOControl2 Register. VGP is enabled by setting the VGPEnbit in LDOControl1 to 1.

Applications Regulator (VAPP)

The VAPP regulator is an adjustable regulator that uses an off chip pass device. It has two modes of operation selected by the state of the VAPPCFG terminal. If VAPPCFG is pulled low the VAPP regulator functions as a programmable voltage applications supply. In this mode, VAPP is enabled or disabled using the VAPPEn bit of LDOControl1.

Down-Converting Mixers

Two quadrature mixers are used to mix down the signals from the LNAs, one for the high bands (1800 and 1900 MHz) and one for the low bands (850 and 900 MHz). The outputs of the mixers are connected to the baseband section through an integrated single pole filter with nominal cut-off frequency of 800kHz.

3.3.2.1 Receiver

Low Noise Amplifiers

The LNAs have differential inputs which help minimize the effect of unwanted interferers. The voltage gain of the LNAs is typically 24 dB. Each LNA can be switch to a low gain mode when receiving large input signals as part of the AGC system.

Transmitter Overview

The highly integrated transmit section of the AD6546 radio has been designed to fully support 8 PSK modulation for EDGE applications, and GMSK modulation for GSM. A translational loop is used for phase modulation, and for 8 PSK additional envelope (AM) circuits are enabled to implement a Polar modulator.

Quadrature Modulator

The Quadrature modulator takes the baseband I/Q signals and converts this onto a complex modulated signal (containing both amplitude and phase information) at the TX IF frequency. After bandpass filtering the TX IF signal is used as the reference input to the Phase Frequency Detector (PFD) for the transmit PLL, and in EDGE mode also provides the input to the Reference Path Log Detector circuit for AM restoration.

3. TECHNICAL BRIEF



The keypad interface supports a row/column decoding of a keyboard matrix of up to 8 rows and 8 columns. The interface generates an interrupt when any key is pressed, and the interrupt is routed through the system interrupt controller to the MCU. Software must scan the columns to determine which key was pressed. Debouncing must also be implemented in software. The keypad interface consists of eight tristateableKEYPADCOL outputs and eight KEYPADROW inputs. Pressing a key pulls the corresponding KEYPADROW input low. When all KEYPADCOL outputs are driven low, pulling any KEYPADROW input low generates an interrupt.In the interrupt service routine, the keypad must be scanned by setting only one column output low at a time and reading the row inputs. A zero is read anywhere a key is pressed on that column. The scan should be repeated at regular intervals until no key is being pressed. To implement debouncing, the software must require the same scan result for several scans. The keypad interrupt should not be cleared until no keyhas been pressed for several scans.The 8 by 8 matrix of rows and columns provides the possibility of up to 64 keys (with an additional 8 if a ghost column is used). Full flexibility in enabling and disabling individual rows and columns is provided. Any rows or columns not used should be disabled in the Keypad Control Register. The following figure shows the keypadinterface and interrupt generation logic.

3.12 Audio Interface

Figure 3-12-1 ABB Internal Audio Block Diagram

The AD6725 Audio Section supports communications and personal audio applications. The Audio Section provides an audio codec with two digital-to-analog converters and an analog-to-digital converter, a microphone interface, and analog input and output channels.

Audio and Music Serial Ports

The AD6725 Audio Serial Port is described in detail in the Audio Serial Port (ASPORT) section below. AD6725 Music serial port (MSPORT) is described in detail in the Music Serial Port (MSPORT) section below.

Audio Codec

The AD6725 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 AD6725 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 right-channel digital input.




3. TECHNICAL BRIEF



Audio codec operating modes can be controlled by writing 5 bit codes in the AudModefield of the AudControl1 register and in the AudMode_M 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.The AudControl1 and AudControl4 contain control bits that allow system software to turn on three audio loudness enhancement techniques meant for use when driving 8 ohm loudspeakers. These are high pass filter, dynamic range compressor, and x4 gain boost.These loudness enhancement techniques can be used with any AudMode or AudMode_M setting. And are programmed seperately and independently for the ASPORT and MS- PORT PCM audio decoder data streams.

Analog Audio Output & Input Configurations

Output configurations are set by AudOS[4:0] bits in the AudControl2 register. Input configurations are set by AudIS[3:0] bits in the AudControl2 register.AudIn3LMute bit high in the AudMuteControl register (0x27 ). For configurations using “DAC2+AIN3R”, the AIN3R input may be muted by setting AudIn3RMute bit high in the AudMuteControl register. For configurations using “AIN3(L)”, the AIN3L and AIN3R inputs may be used as a differential input or the AIN3L input may be used as a single-ended input.Single ended configuration is chosen by setting AudIn3Cfg bit high in the AudControl3 register (0x32 ).

Audio DACs and Analog Filters

The Audio DACs are over-sampled switched-capacitor DACs. The analog filters are switched-capacitor filters followed by active-RC filters.



3. TECHNICAL BRIEF



Analog Audio Output Drivers

Audio Output 1

PGA gain for Audio Output 1 can be set by using bits AudOut1Gain[4:0] in the AudOut12Control (0x21 ) register. Output 1 is used for 32Ω interface with differential output but can be used by single ended interface.And this model only uses passive filters between output port and Receiver.

Figure 3-12-2 ABB Audio OUTPUT1

Audio Output 2

PGA gain for Audio Output 2 can be set by using bits AudOut2Gain[4:0] in the AudOut12Control (0x21) register. Output 2 is used for 8Ω. This port supports only a differential interface. And this model only uses passive filters and Class D audio amplifier between output port and speaker and HS call. Audio amplifier Gain is set by hardware component and Amp gain control.





3. TECHNICAL BRIEF



Audio Output 3

PGA gain for Audio Output 3 Stereo Configuration can be set by using bits AudOutL- Gain[4:0] and AudOutRGain[4:0] in the AudOutLRControl (0x22 ) register. When Audio Output 3 configured as monophonic differential output PGA gain can be set by using bits AudOut3Gain[4:0] in the AudOut3Control register (0x23 ).This port is used for headset speaker in stereo. This port must use DC-coupling capacitor as output DC. It uses two 220nF capacitor each other in left and right output.


Analog Audio Input

The AD6725 provides two analog input channels, AIN1 and AIN2, that may be used for both microphone and line inputs. The AIN1 and AIN2 channels are identical. One of the two channels is typically used with microphone built into a handset. The other channel is typically used with an external microphone or external line input.

Figure 3-12-5 Audio Input Block Diagram



3. TECHNICAL BRIEF



Analog Input AIN1, AIN2 and VMIC configurations can be chosen by setting bits AudIS[3:0] in the AudControl2 register (0x1E ). Additional gain of 9dB can be inserted into Analog Audio Input signal chain by setting AudPreampGainSel bit high in the AudControl3 register (0x32 ).

Microphone Interface

The microphone pre-amplifier and associated integrated resistors support electret microphones. An internal (Configuration 11) or external (Configuration 01 or 10) load resistor converts the current input of the microphone to a voltage signal which is amplified using a low-noise pre-amplifier. The Microphone signal path also includes an additional programmable gain of +9 dB gain directly after the pre-amplifier. Different microphones require different DC bias currents for optimum sensitivity.

Audio ADC and PGA

The Audio ADC is a high-order single-bit sigma-delta ADC that includes a switched- capacitor PGA at the input.

Digital Filters

The AD6725 Audio Section provides two digital filters. The voiceband filter is used for applications with a 8 kHz digital sample rate. The high-quality audio filter is used for applications with higher digital sample rates.




3. TECHNICAL BRIEF



Audio Accessory Detection

The AD6725 provides for detection of audio headset accessory insertion, extraction, and hookswitch events. The detector circuit is designed to operate with minimum power in standby mode. There are two pins dedicated to the accessory detector. AccDet is intended to interface to the external microphone and monitorits bias voltage. The ACCDET terminal is used to sense hookswitch events while a headset accessory is inserted. The JackSense terminal is interfaced to the switch pin of the Jack socket or a Jack Sense terminal on a handset system connector.

Use of the AccDet Terminal for Hookswitch Event Detection

The AccDet terminal may be connected directly to the Ain2P pin in the case of a DC coupling of the accessory microphone. If the accessory microphone is connected via a capacitor then the AccDet pin may be connected to the microphone side of the coupling capacitor. The AccDet terminal is used to detect hookswitch events. Hookswitch events cause the system to answer an incoming phone call or hang up on an active phone call.The detector circuit is in operation only if an accessory is inserted. It monitors the voltage at the AccDetterminal using a comparator as shown Figure below. Associated logic then provides the AudAccInt interrupt and updates the contents of the Detector Control register as follows on each comparator transition

Figure 3-12-6 Audio Accessory Detection Block Diagram



3. TECHNICAL BRIEF



Use of the JackSense Terminal for Accessory Insertion and Removal Detection

Accessory insertion and removal is detected using the JackSense terminal. The JackSense terminal is connected to a signal produced by a mechanical connection that indicates the presence or absence of the headset accessory. The insertion/removal sense circuit fed by JackSense is flexible as far as the characteristics of the mechanical connection are concerned. The mechanical connection will often times be pulled down in one state and floating in the other. In such cases a 1uA on chip current source is used to pull JsckSense to VBAT when the mechanical connection is floating.To avoid false interrupts the Accessory detect logic has a hardware polling loop which will prevent Interrupt generation from comparator transitions with a duration of no less than 10 mSec.

3. TECHNICAL BRIEF



3.14 KEY BACLKLIGHT LED Interface

The AD6725 Auxiliary Section provides three independent PWM light controllers.

The PWM output controllers regulate the average current through active lights.

Figure 3-14-1 ABB Light Controller Block Diagram

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 )



he output duty cycles of the PWM output controllers are set by the LightxDutyCycle[7:0] control registers –Light1DutyCycle (0x2D ), Light2DutyCycle (0x2E) and Light3DutyCycle (0x30 ).

This model use only Light3 port and 2 high luminance white LED with light guard film.
