DESCRIPTION
The STA120 is a monolithic CMOS device that re-
ceives and decodes audio data according to the
AES/EBU, IEC 958, S/PDIF, & EIAJ CP-340/1201
interface standards.
The STA120 recovers the clock and synchroniza-

tion signals and de-multiplexes the audio and dig-
ital data. Differential or single ended inputs can be
decoded.
The STA120 de-multiplexes the channel, user and
validity data directly to serial output pins with ded-
icated output pins for the most important channel
status bits.
