CS8420
Digital Audio Sample Rate Converter
Features
Complete IEC60958, AES3, S/PDIF, EIAJ
General Description
The CS8420 is a stereo digital audio sample rate converter (SRC) with AES3-type and serial digital audio inputs, AES3-type and serial digital audio outputs, and includes comprehensive control ability via a 4-wire microcontroller port. Channel status and user data can be assembled in block-sized buffers, making read/modify/write cycles easy. Digital audio inputs and outputs may be 24, 20, or 16 bits. The input data can be completely asynchronous to the output data, with the output data being synchronous to an external system clock. The CS8420 is available in a 28-pin SOIC package in both Commercial (-10º to +70º C) and Automotive grades (-40º to +85º C).
