ES1990 Canyon3D2LE

PCI Audio Accelerator

Product Brief

DESCRIPTION

The ES1990 Canyon3D™2LE PCI audio accelerator

combines advanced audio functionality in a highly

integrated, single-chip, PCI solution for advanced

multichannel PC audio. With key features, including

hardware acceleration, 3D audio support, and integrated

quad DAC AC‘97 codec, the Canyon3D-2LE will engulf

the user in a 3D world of sound when used with general

applications, digital music, or games.

The ES1990 combines the advantages of a high-

bandwidth PCI bus interface, proven Canyon3D digital

signal processing (DSP) hardware architecture, high-

fidelity quad DAC AC‘97 codec into a single-chip package

with external AC-link for additional future functionality. The

result is robust PC audio functionality, which features

digital mixing, sample rate conversion, realtime effects

processing, multistream DirectSound hardware

acceleration, and head-related transfer function (HRTF)

filtering.

The 3D audio support and HRTF filtering are licensed

through Sensaura™ Ltd. The HRTF filtering is supported

for 2- and 4-speaker outputs, using MultiDrive

technology. The 3D audio is supported through

DirectSound 3D, A3D 1.0, EAX 1.0, EAX 2.0, and I3DL2

advanced programming interfaces (APIs). Additional 3D

audio enhancements are available through MacroFX™,

EnvironmentalFX, and ZoomFX.

The ES1990 meets PC99/PC2001 and Microsoft WHQL

specifications. Device drivers for the ES1990 are

optimized for use on the Microsoft Windows operating

systems and are designed specifically to take advantage

of new features available through Microsoft’s DirectX 8.

Operating at 3.3V digital and 5.0V analog, the ES1990 is

compliant with the Advanced Power Management (APM)

1.2, Advanced Configuration and Power Interface (ACPI)

2.0, and PCI Power Management Interface (PPMI) 1.1

specifications.

The ES1990 Canyon3D-2LE is available in an industry-

standard 100-pin low-profile quad flat pack (LQFP)

package.
