Product specification
Car radio Digital Signal Processor (DSP)
SAA7706H
Noise generator allows for frequency response
measurements
Boot-up ROM for fast start-up
Signal level, noise and multipath detection for AM or FM
signal quality information
AM co-channel and adjacent channel detection (not in
all rom_codes available).
2
APPLICATIONS
High-end car radio systems.

GENERAL DESCRIPTION
The SAA7706H performs all the signal functions in front of
the power amplifiers and behind the car radio tuner
AM and FM outputs and the CD, tape and phone inputs.
These functions are:
Interference absorption
Stereo decoding for FM and AM (stereo)
RDS-demodulation
FM and AM weak signal processing (soft mute, sliding
stereo and high cut)
Dolby-B tape noise reduction
CD de-emphasis function
Audio controls for volume, balance, fader, tone and
dynamics compression.
Some functions have been implemented in hardware
(FM stereo decoder, RDS-demodulator and
FM InterferenceAbsorptionCircuit(IAC)andarenotfreely
programmable.
Digital audio signals from external sources with the Philips

S-busandtheLSB-justified16, 18, 20 and 24 bitsformat
or SPDIF format are accepted.
The big advantage of this SAA7706H device is the ‘dual
media support’; this enables independent front seat and
rear seat audio sources and control.
