The TDA9859 provides control facilities for the main and the SCART channel of a TV set. Due to extended switching possibilities, signals from three stereo sources can be handled.

A Universal Hi-Fi Audio Processor typically refers to an integrated circuit (IC) or a system that provides a range of audio processing functions and features to enhance the audio quality and provide advanced audio capabilities in Hi-Fi (high-fidelity) audio systems.


• Multi-source selector switches six AF inputs (three stereo sources or six mono sources)

• Each of the input signals can be switched to each of the outputs (crossbar switch)

• Outputs for loudspeaker channel and peri-TV connector (SCART)

• Switchable spatial stereo and pseudo stereo effects

• Audio surround decoder can be added externally

• Two general purpose logic output ports

• I2C-bus control of all functions […]
