8-CHANNEL HIGH DEFINITION AUDIO CODEC
DESCRIPTION
The STAC9220 is a high fidelity, 8-channel audio CODEC
compatible with Intel’s High Definition (HD) Audio Interface. The
STAC9220 CODEC provide stereo 24-bit resolution with sample
rates up to 192 KHz. SPDIF I/O provides connectivity to consumer
electronic equipment. The STAC9220 CODEC incorporate IDT's
proprietary
ΣΔ
technology to achieve an estimated DAC SNR in
excess of 95dB. The STAC9220 CODECs provide high quality,
HD Audio capability to notebook and media centric desktop PC
applications.
