DESCRIPTION

The STA020D is a monolithic CMOS device

which encodes and transmits audio data accord-

ing to the AES/EBU, IEC 958, S/PDIF, & EIAJ

CP-340 interface standards. It supports 96kHz

sample rate operation

The STA020D accepts audio and digital data

which is then multiplexed, encoded and driven

onto a cable.

The audio serial port is double buffered and ca-

pable of supporting a wide variety of formats.

The STA020D multiplexes the channel, user, and

validity data directly from serial input pins with

dedicated input pins for the most important chan-

nel status bits.
