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 multi­channel 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 high­bandwidth 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 industry­standard 100-pin low-profile quad flat pack (LQFP)
package.
