ALC898数据手册
1. General Description The ALC898 is a 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, Blu-rayTM DVD, or HD DVD discs. The ALC898 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. Two 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 ALC898 incorporates Realtek proprietary converter technology to achieve 110dB 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 eight analog output ports (port-A to port-H). All analog I/Os can be re-tasked according to user’s definitions. Support for 16/20/24-bit S/PDIF 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 ALC898 features secondary S/PDIF-OUT output and converter that transport digital audio output to a High Definition Media Interface (HDMI) transmitter. The ALC898 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 ALC898 provides the highest sound quality, providing an excellent entertainment package and game experience for PC users.
