Support parallel 4-wire power switch interface

The ALC655 is a 16-bit, full duplex AC'97 2.3 compatible six channels audio CODEC designed for PC multimedia
systems, including host/soft audio and AMR/CNR based designs. The ALC655 incorporates proprietary converter
technology to meet performance requirements on PC99/2001 systems. The ALC655 CODEC provides three pairs of
stereo outputs with 5-Bitvolume 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 ALC655 CODEC operates from a 3.3V power supply for use in notebook and PC applications. The
ALC655 integrates 50mW/20ohm headset audio amplifiers at

Front-Out and Surr-Out, built-in 14.318M 24.576MHz PLL and PCBEEP generator, those can save BOM costs. The
ALC655 also supports the S/PDIF input and output function, which can offer easy connection of PCs to consumer
electronic products, such as AC3 decoder/speaker and mini disk devices. ALC655 supports host/soft audio from Intel
ICH6 chipsets as well as audio controller based VIA/SIS/ALI/AMD/nVIDIA/ATI chipset. Bundled Windows series
drivers (WinXP/ME/2000/98/NT), EAX/

Direct Sound 3D/ I3DL2/ A3D compatible sound effect utilities (supporting Karaoke, 26-kind of environment sound
emulation,10-band equalizer), HRTF 3D positional audio and Sensaura™ 3D (optional) provide an excellent
entertainment package and game experience for PC users. Besides, ALC655 includes Realtek’s impedance sensing
techniques that makes device load on outputs and inputs can be detected.
