ES1992 Canyon3D2 PCI Audio Accelerator Product Brief ESS Technology, Inc. DESCRIPTION FEATURES The ES1992 Canyon3DTM2 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 SensauraTM 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. High-performance single-chip PCI audio acceleration Four-speaker analog output S/PDIF digital output Integrated high-fidelity AC`97 codec High-quality sample rate conversion and digital mixing External AC-Link interface for 6-speaker, 5.1 channel support Multistream DirectSound 3D hardware acceleration Sensaura 3D positional audio Realtime effects processing Full-legacy DOS game support, using TDMA, PC/PCI, or DDMA hardware implementation methods * Five-band hardware equalization POWER MANAGEMENT * Compliance with APM 1.2, ACPI 2.0, and PPMI 1.1 * 3.3-volt digital operation with 5V-tolerant inputs * 5.0-volt analog operation COMPATIBILITY * Supports PC DOS games and applications for SoundBlaster and SoundBlaster Pro * Supports Microsoft Windows DirectSound * Meets PC99/PC2001 and Windows Hardware Quality Laboratory (WHQL) specifications * Supports A3D 1.0, EAX 1.0, EAX 2.0, and I3DL2 APIs 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. ESS Technology, Inc.
