Description

Realtek Audio Driver 4.06 for Windows 98/Me/2000/XP/2003 (32/64 bits) supports all ALC series audio chipsets from ALC101 up to ALC861. It is used as onboard sound on many motherboards.

The ALC650 is an 18-bit, full duplex AC’97 2.2 compatible stereo audio CODEC designed for PC multimedia systems, including host/soft audio and AMR/CNR based designs. Moreover, it 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 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.

Supports host/soft audio from Intel 810/815/820/845 chipsets as well as audio controller based VIA/SIS/ALI chipsets. Finally, internal PLL circuits generate required timing signals, eliminating the need for external clocking devices.

Applications:

Multimedia PCs
3D PC games
Information appliances (IA)
Voice recognition
Audio conferencing
