CS8406-CSZ Datasheet PDF - Cirrus Logic

General Description

●The CS8406 is a monolithic CMOS device which encodes and transmits audio data according to the AES3, IEC60958, S/PDIF, or EIAJ CP1201 standards. The CS8406 accepts audio and digital data, which is then multiplexed, encoded, and driven onto a cable. The audio data is input through a configurable, 3-wire input port. The channel status and user bit data are in put through an SPI™ or I²CTM microcontroller port, and may be assembled in block-sized buffers. For systems

●with no microcontroller, a Stand-Alone Mode allows direct access to channel status and user bit data pins.
