Realtek PDF datasheets for ALC663

The ALC663 is a 5.1 Channel High Definition Audio Codec designed for Microsoft Windows systems. It meets the current WLP3.10 (Windows Logo Program) and future WLP requirements that become effective from 01 June 2008.

Featuring three stereo DACs, two stereo ADCs, legacy analog input to analog output mixing, one stereo digital microphone converter, and two independent S/PDIF output converters, the ALC663 provides a fully integrated audio solution for multimedia desktop and mobile PCs, and ultra mobile devices.

The ALC663 integrates two stereo ADCs and one stereo digital microphone converter to support simultaneous analog microphone recording and digital microphone recording, and features Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) for voice applications.

Multiple analog IO (except MONO, PCBEEP, and HP-OUT) are input and output capable, and provide headphone amplifiers. Four linear headphone amplifiers are integrated to drive earphones on port-A, port-D, port-E and port-F. The fifth headphone amplifier on port-I (HPOUT) is designed to drive an earphone without the need for external DC blocking capacitors, reducing pop noise and enhancing sound quality.

The ALC663 provides two independent S/PDIF outputs and supports 16/20/24-bit S/DPIF output with a sampling rate of up to 192kHz, offering easy connection of PCs to high quality consumer electronic products such as digital decoders and speakers. In addition to the standard (primary) S/PDIF output function, the ALC663 features another independent (secondary) S/PDIF-OUT output and converters that transport digital audio output to a High Definition Media Interface (HDMI) transmitter (becoming more common in high-end PCs).

In addition to the audio functions, the ALC663 supports enhanced power management. Its power management design conforms to Intel’s Audio Codec low power state white paper and is ECR compliant, reducing power consumption when the audio function is not being used, and offering jack detection wake-up when the system is in power down state so as to extend battery life for mobile systems without sacrificing audio features.

The ALC663 supports host audio controller from the Intel ICH series chipset, and also from any other HDA compatible audio controller. With software utilities like Karaoke mode, environment emulation, multi-band software equalizer, dynamic range compressor and extender, optional Dolby® Digital Live, DTS® CONNECT™, Dolby® Home Theater, and SRS® programs, the ALC663 provides an excellent home entertainment package and game experience for PC users.
