CS8421-CZZ - Brand New Cirrus Logic Special Purpose Audio ICs
-
Description
The CS8421-CZZ is a 32-bit, high-performance, monolithic CMOS stereo asynchronous sample-rate converter. It supports digital audio inputs and outputs of 32, 24, 20, or 16 bits. The input and output data can be completely asynchronous or synchronous to an external clock. It can also operate without any external clock by using its integrated oscillator. The CS8421-CZZ features configurable 3-wire input/output ports and does not require any software control. It is suitable for various applications including digital recording systems, digital mixing consoles, high-quality D/A, effects processors, computer audio systems, and automotive audio systems. It can also be used as an asynchronous decimation or interpolation filter.
