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.
