Yamaha AC-XG (YMF753) AC'97

OVERVIEW

YMF753 is an AC’97 Audio CODEC LSI, which is fully compliant with the industry standard “Audio

CODEC ’97” component specification (Revision 2.2).

Different from former AC’97, YMF753 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

• AC’97 Revision 2.2 Compliant

• Analog Inputs :

- 4 Stereo Inputs: LINE, CD, VIDEO, AUX

- 2 Monaural Inputs: Speakerphone and PC BEEP Inputs

- 2 Independent Microphone Inputs

• 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)

• SPDIF Output for AC’97 Revision 1.0 Compliant

• Different audio data from AC-Link can be output to SPDIF and Line Out

• Supports 3D Enhancement (Wide Stereo), and Bass / Treble control

• Multiple CODEC Capability

• Programmable Power Down Mode

• Supports EAPD (External Amplifier Power Down)
