3.3 Major Sub-systems
3.3.1 Audio Interface
The motherboard includes High Definition integrated audio function support, using the ICH6
integrated audio controller and a SigmaTel STAC9200. The STAC9200 is a high quality, 2-channel
audio codec compatible with the Intel High Definition (HD) Audio Interface. The STAC9200 provides
Stereo 24-Bit resolution with sample rates up to 192kHz. The STAC9200 incorporates SigmaTel's
proprietary SD technology to achieve an estimated DAC SNR in excess of 100dB. See Figure 8.
