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.
