General Description
The CS8406 is a monolithic CMOS device which en-
codes and transmits audio data according to the AES3,
IEC60958, S/PDIF, or EIAJ CP1201. The CS8406 ac-
cepts audio and digital data, which is then multiplexed,
encoded and driven onto a cable.
The audio data is input through a configurable, 3-wire in-
put port. The channel status and user bit data are input
through an SPI or I
2
C microcontroller port, and may be
assembled in block sized buffers. For systems with no
microcontroller, a stand alone mode allows direct ac-
cess 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, and computer and automotive audio
systems.
