duc ^DESCRIPTION
ro ^{The STA020D is a monolithic CMOS device which}
P ^{encodes and transmits audio data according to the}
AES/EBU, IEC 958, S/PDIF, & EIAJ CP-340 inter-
te _{face standards. It supports 96kHz sample rate op-}
le ^eration
o _{The STA020D accepts audio and digital data}
bs ^{which is then multiplexed, encoded and driven}
onto a cable.
- ^O The audio serial port is double buffered and capa-
t(s) ^{BLOCK DIAGRAM}
ble 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.
