[Crystal Semiconductor]

General Description
The CS8401/2A are monolithic CMOS devices which encode and transmit audio data according to the AES/EBU, IEC 958, S/PDIF, & EIAJ CP-340 interface standards. The CS8401/2A 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.
