CS4614

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.

The CS4614 is a high performance pin-compatible upgrade to the 100-pin CS4610/11 PCI audio accelerator.With the added legacy compatibility modes, the CS4614 enables real mode DOS compatible PCI-only audio subsystems. This device,combined with application and driver software,provides a complete system solution for hardware acceleration of Windows 95^® DirectSound^®,DirectSound3D^®, DirectInput, and Wavetable Synthesis.WDM drivers provide support for both Windows 98 and Windows NT 5.0.

The CS4614 is based on the Cirrus Logic Crystal-Clear Stream Processor (SP) DSP core. The SP core is optimized for digital audio processing, and is powerful enough to handle complex signal processing tasks with ease. The SP core is supported by a bus mastering PCI interface and a built-in dedicated DMA engine with hardware scattergather 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.

The all-digital CS4614 supports a variety of audio I/O configurations including direct connection to the CrystalClear CS4297 AC '97 Codec.PC/PCI, DDMA, and CrystalClear Legacy support provide PCI-only legacy games compatibility.
