ALC889数据手册Realtek中文资料规格书

描述 Description

The ALC889-GR/ALC889DD-GR is a high-performance multi-channel High Definition Audio Codec with Realtek proprietary loss-less content protection technology that protects pre-recorded content while still allowing full-rate audio enjoyment from DVD audio, Blue-ray DVD, or HD DVD discs. The ALC889 provides ten DAC channels that simultaneously support 7.1 sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo outputs. Three stereo ADCs and one stereo digital microphone converter are integrated and can support a microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technologies. The ALC889 incorporates Realtek proprietary converter technology to achieve 108dB Signal-to-Noise ratio (SNR) playback (DAC) quality and 104dB SNR recording (ADC) quality, and is designed for Windows Vista premium desktop and laptop systems.All analog I/O are input and output capable, and headphone amplifiers are also integrated at six analog output ports (port-A to port-F). All analog I/Os can be re-tasked according to user’s definitions.Support for 16/20/24-bit SPDIF input and output with up to 192kHz sample rate offers easy connection of PCs to consumer electronic products such as digital decoders and speakers. The ALC889 also features secondary SPDIF-OUT output and converter to transport digital audio output to a High Definition Media Interface (HDMI) transmitter.  The ALC889 supports host audio from the Intel chipsets, and also from any other HDA compatible audio controller. With various software utilities like environment sound emulation, multiple-band and independent software equalizer, dynamic range compressor and expander, optional Dolby® Digital Live, Dolby® PCEE program and DTS® CONNECT™, the ALC889 provides the highest sound quality, providing an excellent entertainment package and game experience for PC users.
