Introduction

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. It is available in a 28-pin SOIC package in both Commercial (-10°C to +70°C) and Automotive grades (-40°C to +85°C).
