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.
