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.
