Datasheet - production data
Description
The STA020 is a monolithic CMOS device which
encodes and transmits audio data according to
the AES/EBU, IEC 958, S/PDIF, & EIAJ CP-340
interface standards. It supports 96 kHz sample
rate operation.
The STA020 accepts 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 STA020 multiplexes the channel, user, and
validity data directly from the serial input pins with
dedicated input pins for the most important
channel status bits.
