NXP Semiconductors TDA9860
The TDA9860 provides control facilities for the main, the headphone and the SCART channel of a TV set. July 1994 4 Philips Semiconductors Preliminary specification Universal HiFi audio processor for TV FUNCTIONAL DESCRIPTION The TDA9860 consists of the following functions: • source select switching block • loudspeaker channel with effect controls • headphone channel • two port outputs for general...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.
