Preliminary speciﬁcation

Universal HiFi audio processor for TV

TDA9860

FEATURES

• 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, headphone 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.

GENERAL DESCRIPTION

The TDA9860 provides control facilities for the main, the

headphone and the SCART channel of a TV set. Due to

extended switching possibilities, signals from 3 stereo

sources can be handled.
