Digital Audio Interface Transmitter 1TX 1RX 28-Pin SOIC

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 input through an SPI or I²C 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.The CS8406 is available in a 28-pin TSSOP and SOIC package for both Commercial (-10º to +70ºC) and Automotive grade (-40º to +85ºC). The CDB8416 Demonstration board is also available for device evaluation and implementation suggestions. Target applications include A/V Receivers, CD-R, DVD receivers, digital mixing consoles, effects processors, set-top boxes, and computer and automotive audio systems.
