FEATURES
1.1
Hardware
5-bitstream 3rd-order sigma-delta Analog-to-Digital
Converters (ADCs) with anti-aliasing broadband input
filter
1-bitstream1st-ordersigma-deltaADCwithanti-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)
inputstagesforvoicesignalsfromphoneandnavigation
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: I
2
S-bus or LSB-justified format
Two digital inputs: SPDIF format
Co-DSP support via I
2
S-bus or LSB-justified format
Audio output short-circuit protected
I
2
C-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
°
C operating temperature range
Easy applicable.
