TDA9860 Datasheet, PDF (2/18 Pages) NXP Semiconductors – Universal HiFi audio processor for TV

Philips Semiconductors
Universal HiFi audio processor for TV
Preliminary specification
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.
