DESCRIPTION
The CS4622/24 is a high performance pin-compat-
ible upgrade to the 128-pin CS4610C PCI audio
accelerator. With the added legacy compatibility
modes, the CS4622/24 enables real mode DOS
compatible PCI-only audio subsystems. This de-
vice, combined with application and driver
software, provides a complete system solution for
hardware acceleration of Windows 95

Wavetable Synthesis. WDM drivers provide sup-
port for both Windows 98 and Windows NT 5.0.
DirectInput,
and
The CS4622/24 is based on the Cirrus Logic Crys-
talClear Stream Processor (SP) DSP core. The SP
core is optimized for digital audio processing, and
is powerful enough to handle complex signal pro-
cessing tasks such as Dolby Digital AC-3 decoding
(CS4622 only) with ease. The SP core is support-
ed 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.
The all-digital CS4622/24 supports a variety of au-
dio I/O configurations including direct connection
to the CrystalClear CS4297 AC ‘97 Codec. A sec-
ondary AC ‘97 2.0 interface provides support for
multi-channel and digital docking solutions. Added
extended I/O supports DAA control for modem
applications.
Consumer Digital input and output (S/PDIF) inter-
faces support both PCM and compressed 5.1
digital data formats.
PC/PCI, DDMA, and CrystalClear Legacy support
provide PCI-only legacy games compatibility.
