ALC262 Series
Datasheet
1.
General Description
The ALC262 series are 4-Channel DAC and 6-Channel ADC High Definition Audio Codecs with UAA
(Universal Audio Architecture). Featuring two 24-bit stereo DACs and three 24-bit stereo ADCs (the
ALC262, ALC262-VB and ALC262-VC support 20-bit ADC format, the ALC262-VD supports 24-bit
ADC format), they are designed for high-performance multimedia desktop and laptop systems. The
ALC262 series incorporates proprietary converter technology to achieve over 100dB Signal-to-Noise
ratio playback quality.
®
The ALC series meets the current WLP3.10 (Windows
Logo Program) requirements, and the
ALC262-VD (D version) meets future WLP requirements that become effective from 01 June 2008,
bringing PC sound quality closer to consumer electronic devices.
The ALC262 series provide 4 channels of DAC, supporting stereo sound playback on the rear panel and
independent stereo sound output on the front panel simultaneously (multiple streaming), along with
flexible mixing, mute, and fine gain control functions to provide a complete integrated audio solution.
The ALC262 series also integrates three stereo ADCs that can support a microphone array with Acoustic
Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technology simultaneously,
significantly improving sound quality for PC VoIP applications. With this unique feature (3 stereo ADCs),
the ALC262 can provide high-quality audio using S/PDIF to output analog data, or for multiple-source
recording applications.
All analog IO are input and output capable and can be re-tasked according to user’s definitions.
Headphone amplifiers are also integrated at analog output ports A, B, C, D, E, and F. The ALC262 series
supports 16/20/24 S/PDIF input and output to offer easy connection of PCs to high quality consumer
electronic products such as digital decoders and speakers.
The ALC262 series supports host/soft audio from the Intel ICH chipset, and also from any other HDA
compatible audio controller. With EAX/Direct Sound 3D/I3DL2/A3D compatibility, and excellent
software utilities like Karaoke mode, environment emulation, software equalizer, HRTF 3D positional
