/ h2 J3 ~9 w: p7 v& Z2 J4 U1 KThe CS8406 is a monolithic CMOS device which encodes and transmits audio data according to the AES3,IEC60958, S/PDIF, o r EIAJ CP1201 standards. The
CS8406 accepts audio and digital data, which is thenmultiplexed, encoded, and driven onto a cable.

may be assembled in block-sized buffers. For systemswith no microcontroller, a Stand-Alone Mode allows direct access to channel status and user bit data pins.
