Description
The CS4205 is an AC ’97 2.1 compliant stereo audio co-
dec designed for PC multimedia systems. It uses
industry leading CrystalClear® delta-sigma and mixed
signal technology. The CS405 is the first Cirrus AC ’97
audio codec to feature digital centric mixing and digital
effects. 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 CS4205 with a PCI audio accelerator or
core logic supporting the AC ’97 interface implements a
cost effective, superior quality audio solution. The
CS4205 surpasses PC 99, PC 2001, and AC ’97 2.1 au-
dio quality standards.
