Cirrus Logic Inc. CS8405A-CZZ

Description
The CS8405A is a monolithic CMOS device that encodes and transmits audio data according to the AES3, IEC60958, S/PDIF, or EIAJ CP1201 standards.
It accepts audio and digital data, which is then multiplexed, encoded, and driven onto a cable.
The audio data is input through a configurable, 3wire input port.
The channel status and user bit data are input through an SPI or I2C microcontroller port and may be assembled in blocksized buffers.
For systems with no microcontroller, a standalone mode allows direct access to channel status and user bit data pins.
