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 asynchro-
nous, 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 CS8412 is available in a
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
