CDB8421 32-bit / 192 kHz 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.
