CS4207(2009) Datasheet PDF - Cirrus Logic

General Description
   The CS4207 is a highly integrated multi-channel lowpower HD Audio CODEC featuring 192 kHz DACs, 96 kHz ADCs, 192 kHz S/PDIF Transmitters and Receiver, Microphone pre-amp and bias voltage, and a ground centered Headphone driver. Based on multi-bit, delta-sigma modulation, it allows infinite sample rate adjustment between 32 kHz and 192 kHz.
