Advanced Pci Audio Accelerator - National Semiconductor

LM4560 is an advanced PCI Audio accelerator providing full legacy compatibility, wavetable synthesis, DirectMusic, Di- rectSound, and DirectSound3D on a single chip for the high- performance, cost-sensitive consumer market. It supports Sound Blaster functionality and is fully PC98 compliant. The LM4560 integrates a 64-voice wave table engine with per voice effect processing capability. It supports the upcom- ing Microsoft DirectMusic API and is fully compatible with DLS Level 1 (downloadable samples) specification. The LM4560 is optimized for Microsoft Windows 98 and Win- dows NT5.0 WDM streaming architecture with re-routable end-point support. The LM4560 includes DirectSound3D ac- celeration hardware for ITD (Interaural Time Difference), IID (Interaural Intensity Difference), Pan, Delay, and Doppler hardware. The LM4560 supports Sound Blaster Pro/16 DOS games while improving gaming Audio quality. The LM4560 supports both the legacy Analog gameport and a Digital Enhanced Game Port. When coupled with DirectInput driver, the Digi- tal Enhanced Game Port CAN save up to 12% of the CPU overhead nominally required by a conventional Analog game port. The LM4560 employs a high precision 26-bit digital mixer, providing an accurate 20-bit output and higher than 90 dB signal-to-noise ratio when used with high quality AC97 Rev 1.03 and Rev 2.0 codecs. The LM4560 is designed with aggressive power manage- ment. It is PCI Bus Power Management Interface (PPMI 1.0)-compliant. The LM4560 supports multiple Rev 2.0 AC97 codecs, which are useful for notebook docking systems. With a low power, 3.3V process and a space conscious 100 TQFP package, the LM4560 is also well suited for Notebook systems. By National Semiconductor Corporation
