The CS8405A is a monolithic, CMOS device which encodes and transmits audio data according to the AES3, IEC60958, S/PDIF, or EIAJ CP1201 standards. The CS8405A accepts audio and digital data, which it then multiplexes, encodes, and drives 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 micro-controller port and may be assembled in block sized buffers. For systems with no micro-controller, a standalone mode allows direct access to Channel Status and User bit data pins. Target applications include A/V receivers, CD-R, DVD receivers, digital mixing consoles, effects processors, set-top boxes, computers, and automotive audio systems.
