FEATURES
1.1
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 °C operating temperature range
Easy applicable.
1.2
Software
Improved FM weak signal processing
Integrated 19 kHz MPX filter; de-emphasis and stereo
detection
Electronic adjustments: FM or AM level, FM channel
separation, Dolby(1) level
Baseband audio processing (treble, bass, balance,
fader and volume)
Four channel 5-band parametric equalizer
9-bands mono audio spectrum analyzer
Extended beep functions with tone sequencer for phone
rings
Large volume jumps e-power interpolated to prevent
zipper noise
Dual media support; allowing separate front-seat and
rear-seat signal sources and separate control
Dynamic loudness or bass boost
Audio level monitor
Tape equalization and Music Search System (MSS)
detection for tape
Dolby-B tape noise reduction (at 44.1 kHz only)
Dynamics compression available in all modes
CD de-emphasis processing
Voice-over possibility for phone and navigation signals
Improved AM signal processing
Digital AM CQUAM stereo decoder (not in all
rom_codes available)
Digital AM interference suppression
Soft audio mute
RDS update processing: pause detection, mute and
signal-quality sensor-freeze
General purpose tone generator
