PCM9211 (ACTIVE) 216kHz Digital Audio Interface Transceiver (DIX) with Stereo ADC and Routing

 

Description

The PCM9211 is a complete analog and digital front-end for today’s multimedia players, sound bars, 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). In addition, the PCM9211 has two dedicated input channels for HDMI 2.1 eARC compliant frames.
