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.

The CS8401A has a configurable internal buffer memory, loaded via a parallel port, which may be used to buffer channel status, auxiliary data, and/or user data.

The CS8402A multiplexes the channel, user, and validity data directly from serial input pins with dedicated input pins for the most important channel status bits.
