DESCRIPTION
The PCM9211 is a complete analog and digital
front-end for today's multimedia players and
recorders.
The PCM9211 integrates a stereo ADC, 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).
