Copyright © Cirrus Logic, Inc. 2005 (All Rights Reserved) JAN ‘05 DS641PP1 1 CS8421 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 require 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 audio systems. The part is available in space saving 20-pin TSSOP and QFN packages and supports sample rates up to 211 kHz.
