YMF743
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

• PC BEEP can directly output to Line Out
• Internal +20dB amplifier circuitry for microphone
• Analog Outputs : Stereo LINE Output, True LINE Level and Monaural Output
• Supports Zoomed Video Port
• Supports Consumer IEC958 Output Port (SPDIF OUT)
• Supports 3D Enhancement (Wide Stereo), and Bass / Treble control
