The CS4231A includes stereo 16-bit audio converters

and complete on-chip filtering for record and playback

of 16-bit audio data. In addition, analog mixing and

programmable gain and attenuation are included to

provide a complete audio subsystem. A selectable se-

rial port can pass audio data to and from DSPs or

ASICs. Crystal-developed high-performance software

drivers for various operating systems are available that

support all the CS4231A features including full duplex

transfers. The CS4231A is a pin compatible upgrade to

the CS4231 and CS4248.
