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).
