Product Attributes

Introduction

A monolithic CMOS device that receives and decodes one of eight stereo pairs of digital audio data according to the IEC60958, S/PDIF, EIAJ CP1201, or AES3 interface standards. It has a serial digital audio output port and comprehensive control ability through a selectable control port in Software Mode or through selectable pins in Hardware Mode. Channel status data are assembled in buffers, making read access easy. GPO pins may be assigned to route a variety of signals to output pins. A low-jitter clock recovery mechanism yields a very clean recovered clock from the incoming AES3 stream. Stand-alone operation allows systems with no microcontroller to operate it with dedicated output pins for channel status data. Available in 28-pin TSSOP, SOIC, and QFN packages in Commercial grade (-10°C to +70°C) and Automotive grade (-40°C to +85°C).
