DATA SHEET
8-CHANNEL HIGH DEFINITION AUDIO CODEC
DESCRIPTION
The STAC9220/9221/9223 are high fidelity, 8-channel audio
CODECs compatible with Intel’s High Definition (HD) Audio
Interface. The STAC9220/9221/9223 CODECs provide stereo
24-bit resolution with sample rates up to 192 KHz. SPDIF
I/O provides connectivity to consumer electronic equipment. The
STAC9221 CODEC incorporates IDT's proprietary
Σ∆
technology
to achieve an estimated DAC SNR in excess of 105dB. The
STAC9220/9223 CODECs incorporate IDT's proprietary
Σ∆
technology to achieve an estimated DAC SNR in excess of 95dB.
The STAC9223 has all of the features of the STAC9220 plus
ADAT
®
Optical “Lightpipe.”
The STAC9220/9221/9223
CODECs provide high quality, HD Audio capability to notebook
and media centric desktop PC applications.
