Introduction

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 synchronization 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.

The STA120 is a monolithic CMOS circuit that receives and decodes audio and digital data according to the AES/EBU, IEC 958, S/PDIF, and EIAJ CP-340/1201 interface standards. It contains a RS422 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.

The STA120 does not need a microprocessor to handle the non-audio data (although a micro may be used with the C and U serial ports). Instead, dedicated pins are available for the most important channel status bits. The STA120 is a monolithic CMOS circuits that receives and decodes digital audio data which was encoded according to the digital audio interface standards. It contains a clock and data recovery utilizing an on-chip phaselocked loop. The output data is output through a configurable serial port that supports 14 formats. The channel status and user data have their own serial pins and the validity flag is OR'ed with the ERF flag to provide a single pin, VERF, indicating that the audio output may not be valid. This pin may be used by interpolation filters that provide error correction.
