Description

The CS8403A and CS8404A are digital audio transmit-ters which support 96 kHz sample  rate operation. Thedevices encode and transmit audio data according to theAES/EBU, IEC958, S/PDIF,  & EIAJ CP-340  interfacestandards. The CS8403A  and CS8404A accept audio and digital data, which is then multiplexed, encoded and driven onto a cable. The audio serial port is double buff-ered and capable of supporting a wide variety of formats.

The CS8403A has a configurable internal buffer memo-ry, loaded via a parallel port, which may be used to bufferchannel status, auxiliary data, and/or user data.

The CS8404A multiplexes the channel, user, and validitydata directly  from serial  input pins with dedicated inputpins for the most important channel status bits.
