Description
The CS8403A and CS8404A are digital audio transmit-
ters which support 96 kHz sample rate operation. The
devices encode and transmit audio data according to the
AES/EBU, IEC958, S/PDIF, & EIAJ CP-340 interface
standards. 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 buffer
channel status, auxiliary data, and/or user data.
The CS8404A multiplexes the channel, user, and validity
data directly from serial input pins with dedicated input
pins for the most important channel status bits.
