ALC101
Value AC'97 Audio CODEC
 
General Description

The ALC101 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. The ALC101 AC'97 CODEC supports multiple CODEC extensions with independent variable sampling rates and built-in 3D effects. The ALC101 CODEC provides a pair of stereo outputs with independent volume controls 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 ALC101 CODEC operates from a 5V/3.3V power supply with EAPD (External Amplifier Power Down) control for use in notebook and PC applications. The ALC101 integrates a 50mW/20ohm headset audio amplifier into the CODEC, saving BOM costs. The ALC101 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, 26-kind of environment sound emulation, 5-band equalizer) provide an excellent entertainment package for PC users. Finally, internal PLL circuits generate required timing signals, eliminating the need for external clocking devices.
