Description

The CS8413 and CS8414 are monolithic CMOS devices which receive and decode audio data up to 96kHz according 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 validity data directly to serial output pins with dedicated output pins for the most important channel status bits.
