Track ID: JATR-2265-11
Rev. 1.2
1. General Description
The ALC888S-VD provides ten DAC channels that simultaneously support 7.1 channel 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.
All analog I/O are input and output capable, and headphone amplifiers are also integrated at three analog
output ports (port-D/port-E/port-F). All analog I/Os can be re-tasked according to user 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 ALC888S-VD also
features secondary SPDIF-OUT output and converter to transport digital audio output to a High
Definition Media Interface (HDMI) transmitter.
The ALC888S-VD 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 PCEE program,
SRS TruSurround HD, SRS Premium Sound, Fortemedia SAM, Creative Host Audio, Synopsys Sonic
Focus, DTS Surround Sensation | UltraPC, and DTS Connect licenses, the ALC888S-VD offers the
highest sound quality, providing an excellent entertainment package and game experience for PC users.
The ALC888S-VD is an upgraded version of the ALC888S-VC, with lower power consumption. It also
features a built-in Low-dropout (LDO) regulator to reduce customer’s external circuit cost.
