Hardware
- 5-bitstream 3rd-order sigma-delta Analog-to-Digital Converters (ADCs) with anti-aliasing broadband input filter
- 1-bitstream 1st-order sigma-delta ADC with anti-aliasing broadband input filter
- 4-bitstream Digital-to-Analog Converters (DACs) with 128-fold oversampling and noise shaping
- Integrated semi-digital filter; no external post filter required for DAC
- Dual media support: allowing separate front-seat and rear-seat signal sources and separate control
- Simultaneous radio and audio processing
- Digital FM stereo decoder
- Digital FM interference suppression
- RDS demodulation via separate ADC; with buffered output option
- Two mono Common-Mode Rejection Ratio (CMRR) input stages for voice signals from phone and navigation inputs
- Phone and navigation mixing at DAC front outputs
- Two stereo CMRR input stages (CD-walkman and CD-changer etc.)
- Analog single-ended TAPE and AUX input
- Separate AM-left and AM-right inputs in the event of use of external AM stereo decoder
- One digital input: I²S-bus or LSB-justified format
- Two digital inputs: SPDIF format
- Co-DSP support via I²S-bus or LSB-justified format
- Audio output short-circuit protected
- I²C-bus controlled (including fast mode)
- MOST bus interfacing (details in separate manual)
- Phase-locked loop derives the internal clocks from one common fundamental crystal oscillator
- Combined AM/FM level input
- Pin compatible with SAA7705 and SAA7708
- All digital inputs are tolerant of 5 V input levels
- All analog inputs have high GSM immunity
- Low number of external components required
- -40 to +85 Cel operating temperature range
- Easy applicable.
