AN15887A is an I2C bus-embedded IC for switching video 6-channel input and 2-channel output, and audio 5-channel input and 2-channel output. A SAG-compensating video output 75Ωdriver, and a circuit switching gain of 6.0 dB for video signals and audio gain of 0/-6 dB for audio output, etc. are embedded to contribute to rationalized TV system design.
