General Description
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.
