ES1992 Canyon3D2

PCI Audio Accelerator

Product Brief

DESCRIPTION

The ES1992 Canyon3D™2 PCI audio accelerator

combines advanced audio functionality in a highly

integrated single-chip PCI solution for advanced multi-

channel PC audio. With key features including hardware

acceleration, 3D audio support, digital output capability,

and integrated quad DAC AC‘97 codec, the Canyon3D-2

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

general applications, digital music, or games.

The ES1992 combines the advantages of a high-

bandwidth PCI bus interface, proven Canyon3D digital

signal processing (DSP) hardware architecture, five-band

speaker equalization (EQ), high-fidelity quad DAC AC‘97

codec into a single-chip package with an external AC-link

for additional future functionality (i.e., 6-speaker, 5.1

channel output). A Sony/Philips digital interface (S/PDIF)

output provides for digital output of multichannel AC-3

content. 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. HRTF filtering is supported for 2,

4, and 6 speaker outputs, using MultiDrive technology.

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 ES1992 meets PC99/PC2001 and Microsoft WHQL

specifications. Device drivers for the ES1992 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 ES1992 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 ES1992 Canyon3D-2 is available in an industry-

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

package.
