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.

The CS8401A has a configurable internal buffer mem-

ory, 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 valid-

ity data directly from serial input pins with dedicated

input pins for the most important channel status bits.
