STA120 Datasheet | STMicroelectronics

DESCRIPTION The STA120 is a monolithic CMOS device that receives 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 BLOCK DIAGRAM tion signals and de-multiplexes the audio and digital 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 dedicated output pins for the most important channel status bits.
