Realtek PDF datasheets for ALC887

The ALC887-VD is a 7.1 Channel High Definition Audio Codec with two independent SPDIF outputs. Featuring eight DAC channels that simultaneously support 7.1 sound playback, and integrate two stereo ADCs that can support a stereo microphone, and feature Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) for voice applications.

The ALC887-VD supports 16/20/24-bit SPDIF input and output functions with sampling rate of up to 192kHz, offering easy connection of PCs to high quality consumer electronic products such as digital decoders and Minidisk devices. In addition to the standard (primary) SPDIF output function, the ALC887-VD features another independent (secondary) SPDIF-OUT output and converters that transport digital audio output to a High Definition Media Interface (HDMI) transmitter (becoming more common in high-end PCs).

All analog I/O are input and output capable, and headphone amplifiers are also integrated at three analog output ports (port-D/E/F). All analog I/Os can be re-tasked according to user’s definitions.

The ALC887-VD supports host audio controller from the Intel ICH series chipset, and also from any other HDA compatible audio controller. With EAX/Direct Sound 3D/I3DL2 compatibility, and excellent software utilities like environment sound emulation, multiple-band software equalizer and dynamic range control, optional Dolby Digital Live, DTS CONNECT , and Dolby Home Theater programs, the ALC887-VD provides an excellent home entertainment package and game experience for PC users.

The ALC887-VD is an upgraded version of the ALC887 that meets the current WLP3.1x (Windows Logo Program) and future WLP requirements. The ALC887-VD also conforms to Intel’s Audio Codec low power state white paper and is ECR compliant.

The ALC887 is a 7.1 Channel High Definition Audio Codec with two independent SPDIF outputs. Featuring eight channels of DAC support 7.1 sound playback, and integrates two stereo ADC that can support a stereo microphone, and feature Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) for voice applications.

ALC887 is designed not only to meet the premium audio performance requirements in current WLP3.10 (Windows Logo Program), but provides better characteristics for future WLP. That brings user real high fidelity of sound quality.

The ALC887 supports 16/20/24-bit SPDIF input and output functions with sampling rate of up to 192kHz, offering easy connection of PCs to high quality consumer electronic products such as digital speakers. In addition to the standard (primary) SPDIF output function, the ALC887 features another independent (secondary) SPDIF-OUT output and converters that transport digital audio to a High Definition Media Interface (HDMI) transmitter output to HDTV system or A/V receiver, this feature is becoming more common in high-end PCs.

As ALC series HD audio codec, all analog IO are input and output capable, and headphone amplifiers are also integrated at each analog output. That provides flexible design for various system configuration.

Addition to audio functions, ALC887 also conforms to Intel’s Audio Codec low power state white paper and is ECR compliant. This low power design consumes various and less power in different operation mode, and save more power when system is in suspend mode.

The ALC887 supports host audio controller from the Intel ICH series chipset, and also from any other HDA compatible audio controller. With EAX/Direct Sound 3Dcompatibility, and software utilities like environment sound emulation, multiple-band software equalizer and dynamic range control, optional Dolby PCEE program, DTS CONNECT program, the ALC887 provides an excellent home entertainment package and game experience for PC users.
