STMicroelectronics STA120 Digital
Audio Interface Receiver
STMicroelectronics STA120 Digital Audio Interface Receiver is a monolithic CMOS device that receives and decodes audio data according to the AES/EBU, IEC 958, S/PDIF, & AGIO CP-340/1201 interface standards. It contains a RS-422 line receiver and Phase-Locked Loops (PLL) that recovers the clock and synchronization signals and de-multiplexes the audio and digital data. The STA120 de-multiplexes the channel status, user and validity information directly to serial output pins with dedicated pins for the most important channel status bits.
