Therefore, note that unauthorized alternations or repair may affect the regulatory status of the system and may void any remaining warranty.

The AD digital processor interface provides serial ports for control data, baseband transmit and receive data, and two for audio data. 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. Both PA blocks share common power supply pins to distribute current. The purpose of this application note is to discuss the system issues that affect operation of the 32kHz oscillator circuit.

The crystal is connected as shown in figure The Receive path features automatic calibration and tracking to remove DC offsets. GPRS applications up to and including class An integrated band pass filter exists between the mixer and the PFD to filter the mixers unwanted side band and higher order mixing products.

RDS data buffers to simplify the interface with an external host. The AAT is available in a Pb-free, space-saving 2. 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 channels are common in the digital section. The analog filters are switched- capacitor filters followed by active-RC filters.

Class D audio amplifier between output port and speaker. Audio amplifier Gain is set by hardware component and gain is 6 times. The other channel is typically used with an external microphone or external line input. The JackSense terminal is interfaced to the switch pin of the Jack socket or a Jack Sense terminal on a handset system connector.
