Description
The CS8413 and CS8414 are monolithic CMOS devices
which receive and decode audio data up to 96kHz ac-
cording to the AES/EBU, IEC958, S/PDIF, and EIAJ
CP340/1201 interface standards. The CS8413 and
CS8414 receive data from a transmission line, recover
the clock and synchronization signals, and de-multiplex
the audio and digital data. Differential or single ended in-
puts can be decoded.
The CS8413 has a configurable internal buffer memory,
read through a parallel port, which may be used to buffer
channel status, auxiliary data, and/or user data.
The CS8414 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.
