DIX9211 - 216kHz Digital Audio Interface Transceiver (DIX)

The DIX9211 is a complete analog and digital front-end for today’s multimedia players and recorders.

The DIX9211 integrates an S/PDIF transceiver with up to 12 multiplexed inputs and 3x PCM inputs to allow other audio receivers to be multiplexed along with the analog and S/PDIF signals to a digital signal processor (DSP).
