ESS Technology, Inc. SAM0354-060801 1 ESS Technology, Inc. ES1990 Canyon3D 2LE PCI Audio Accelerator Product Brief

DESCRIPTION

The ES1990 Canyon 3D™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 Canyon 3D-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 Canyon 3D 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 Canyon 3D-2LE is available in an industry- standard 100-pin low-profile quad flat pack (LQFP) package.
