The CS8403A and CS8404A are digital audio transmitters 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 buffered and capable of supporting a wide variety of formats.
