Notes: 1. Includes all power generated by AC and/or DC output loading.
2. The power supply pins are at recommended maximum values. XTALI & XTALO are at 3.6 V maximum.
3. At ambient temperatures above 70° C, total power dissipation must be limited to less than 0.4 Watts.
WARNING: Operation beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.


Description

The CS4630 is a high performance upgrade to the CS4624 PCI audio accelerator. With support for legacy compatibility modes, the CS4630 enables real mode DOS compatibility within PCI-only audio subsystems. This device, combined with application and driver software, provides a complete system solution for hardware acceleration of Microsoft's DirectSound, DirectSound3D, DirectInput, and Wavetable Synthesis. WDM drivers provide support for both Windows 98® and Windows 2000®.

The CS4630 is based on the Cirrus Logic CrystalClear™ Stream Processor (SP) DSP core. The SP core is optimized for digital audio processing, and is powerful enough to handle complex signal processing tasks such as Sensaura 3D, 4-channel output, and hardware wavetable synthesis. The SP core is supported by a bus mastering PCI interface and a built-in dedicated DMA engine with hardware scatter-gather support. These support functions ensure extremely efficient transfer of audio data streams to and from host-based memory buffers, providing a system solution with maximum performance and minimal host CPU loading.
