CS4202

Audio CODEC ‘97 with Headphone Amplifier

Overview

Description

The CS4202 is an AC ‘97 2.2-compliant, stereo audio CODEC designed for PC multimedia systems. It uses industry-leading Delta-Sigma and mixed-signal technology. 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 desktop, portable and entertainment PCs.

The CS4202 includes two I²S outputs, which allow for the addition of one or two low-cost stereo digital-to-analog (D/A) converters (CS4334) for 4- or 6-channel audio.

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 audio quality standards. Windows XP and 2000 drivers are available.
