CS8421 Asynchronous Sample Rate Converter

The CS8421 is a 32-bit, high-performance, monolithic CMOS stereo asynchronous sample-rate converter. Digital audio inputs and outputs can be 32, 24, 20, or 16 bits. Input and output data can be completely asynchronous, synchronous to an external data clock, or the part can operate without any extern.
