Philips Semiconductors
Universal hi-fi audio processor for TV
Product 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.
