TDA9859

Universal hi-fi audio processor for TV

NXP Semiconductors. 

Philips Semiconductors

Universal hi-fi audio processor for TV

Preliminary specification

TDA9859

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 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 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.
