General Description
The CS8405A is a monolithic CMOS device which encodes and transmits audio data according to the AES3, IEC60958, S/PDIF, or EIAJ CP1201. The CS8405A 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 input through an SPI or Two-Wire microcontroller port, and may be assembled in block sized buffers. Fo.
