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 soft-
ware control via a control port.
Target applications include digital recording systems (DVD-R/RW, CD-R/RW, PVR, DAT, MD, and VTR), digital mix-
ing consoles, high-quality D/A, effects processors, computer audio systems, and automotive audio systems.
The CS8421 is also suitable for use as an asynchronous decimation or interpolation filter. See Cirrus Logic Appli-
cation Note AN270, “Audio A/D Conversion with an Asynchronous Decimation Filter”, available at
www.cirrus.com
for more details.
