1.3.7AC’97 AUDIO SYSTEM: Advance Logic, Inc, ALC655 | Document |
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 performanceSecretrequirements on PC99/2001 systems. The ALC655 |
MiTac | |
CODEC provides three pairs of stereo outputs with 5-Bitv lume controls, a mono output, and multiple stereo and |
Confidential |
mono inputs, along with flexible mix ng, 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 tegrates 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 ALC655also 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 ICHx chipsets as well as audio controller based VIA/SIS/ALI/AMD/nVIDIA/ATI chipset. Bundled Windows series drivers (Win XP/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.
