Product Summary

The SAA7706H/107 is a car radio digital signal processor (DSP). The SAA7706H/107 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. Some functions of the SAA7706H/107 have been implemented in hardware (FM stereo decoder, RDS-demodulator and FM Interference Absorption Circuit (IAC) and are not freely programmable. Digital audio signals from external sources with the Philips I2S-bus and the LSB-justified 16, 18, 20 and 24 bits format or SPDIF format are accepted. The big advantage of the SAA7706H/107 is the dual media support; this enables independent front seat and rear seat audio sources and control.
