Description

The CS4202 is an AC ’97 2.2 compliant stereo audio co-

dec designed for PC multimedia systems. It uses

industry leading delta-sigma and mixed signal technolo-

gy. This advanced technology and these features are

designed to help enable the design of PC 99 and

PC 2001 compliant high-quality audio systems for desk-

top, portable, and entertainment PCs.

Coupling the CS4202 with a PCI audio accelerator or

core logic supporting the AC ’97 interface implements a

cost effective, superior quality audio solution. The

CS4202 surpasses PC 99, PC 2001, and AC ’97 2.2 au-

dio quality standards.
