General Description

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 external clock

by using an integrated oscillator.

Audio data is input and output through configurable 3-wire input/output ports. The CS8421 does not re-

quire any software control via a control port.

Target applications include digital recording systems (DVD-R/RW, CD-R/RW, PVR, DAT, MD, and VTR),

digital mixing consoles, high quality D/A, effects processors, computer audio systems, and automotive au-

dio systems.

The part is available in space saving 20-pin TSSOP and QFN packages and supports sample rates up to

211 kHz.
