Description
The CS8411/12 are monolithic CMOS devices which re-
ceive and decode audio data according to the AES/EBU,
IEC958, S/PDIF, & EIAJ CP-340 interface standards.
The CS8411/12 receive data from a transmission line,
recover the clock and synchronization signals, and de-
multiplex the audio and digital data. Differential or single
ended inputs can be decoded.
The CS8411 has a configurable internal buffer memory,
read via a parallel port, which may be used to buffer
channel status, auxiliary data, and/or user data.
The CS8412 de-multiplexes the channel, user, and va-
lidity data directly to serial output pins with dedicated
output pins for the most important channel status bits.
