Realtek AC97 ALC650 Audio Codecs 4.06 . for win xp 98/me/2000/XP/2003

he ALC650 incorporates proprietary converter technology to achieve a high SNR, greater than 90 dB. The ALC650 AC'97 CODEC supports multiple CODEC extensions with independent variable sampling rates and built-in 3D effects.

The ALC650 CODEC provides two pairs of stereo outputs with independent volume controls, a mono output, and multiple stereo and mono inputs, along with flexible mixing, gain and mute functions to provide a complete integrated audio solution for PCs. The digital interface circuitry of the ALC650 CODEC operates from a 5V/3.3V power supply with EAPD (External Amplifier Power Down) control for use in notebook and PC applications.

The ALC650 integrates a 50mW/20ohm headset audio amplifier into the CODEC, which can save BOM costs.

The ALC650 also supports an AC'97 2.2 compliant SPDIF out function which allows easy connection from the PC to consumer electronic products, such as AC3 decoder/speaker and mini disk.

The ALC650 CODEC supports host/soft audio from Intel 810/815/820/845 chipsets as well as audio controller based VIA/SIS/ALI chipsets. Bundled Windows series drivers (Win95/98/ME/2000/XP/NT) and sound effect utilities (supporting Karaoke, emulation of 26 sound environments, and 5-band equalizer) provide a more comprehensive entertainment package for PC users. Finally, internal PLL circuits generate required timing signals, eliminating the need for external clocking devices.
