The 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.
The audio data is input through a configurable, 3-wireinput port. The channel status and user bit data are input through an SPI™ or I2C® microcontroller port, and
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.
# P# ~$ Q, X; t  wThe CS8406 is available in a 28-pin TSSOP and SOICpackage for both Co mmercial (-10o to +70oC) andAutomotive grade (-40o to +85oC). The CDB8416Demonstration board is also available for deviceevaluation and implementation suggestions. Please
