AC'97 Revsion2.1 Audio CODEC with Digital Audio I/F
OVERVIEW
YMF743 is an AC'97 Audio CODEC LSI, which is fully compliant with the industry standard "Audio CODEC '97" component specification (Revision 2.1). Different from former AC'97, YMF743 supports new features like SPDIF OUT and Zoomed Video Port. Without using a digital controller, these new features can be enhanced in the AC'97 sound system that has an ICH controller built-in chipset. Low power consumption is supported not only in the normal mode but can be controlled in the power-down mode.
FEATURES
