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. The 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 refer to “Ordering Information” on page 34 for completedetails. Target applications include A/V Receivers, CD-R, DVD receivers, digital mixin g consoles, effects processors, set-top boxes, and computer and automotive audio systems.
