Realtek PDF datasheets for ALC262

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 audio, and optional Dolby®, SRS®, Fortemedia® and Waves® audio technology the ALC262 provides an excellent entertainment package and game experience for PC users.

Two functions are added in ALC262 C version. The first one is the digital microphone interface is supported. The ALC262 C version supports all mainly digital microphones supplied on current market. With digital microphone implementation, especially the laptop system can achieve better voice input quality without noise interference caused by geometric PCB layout and radio frequency devices. The other one is ALC262 C version can support scalable I/O voltage (1.5V to 3.3V) on HDA link, which will be a requirement in future chipsets designed for low voltage operation.
