DESCRIPTION
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).
