With the added legacy compatibility modes, PI293PP1 JUL `98 1 CS4622/24 Description the CS4622/24 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(R) DirectSound(R), DirectSound3D(R), DirectInput, and Wavetable Synthesis. WDM drivers provide support for both Windows 98 and Windows NT 5.0. The CS4622/24 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 Dolby Digital AC-3 decoding (CS4622 only) with ease. 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. The all-digital CS4622/24 supports a variety of audio I/O configurations including direct connection to the CrystalClear CS4297 AC `97 Codec. A secondary 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) interfaces support both PCM and compressed 5.1 digital data formats. PC/PCI, DDMA, and CrystalClear Legacy support provide PCI-only legacy games compatibility. 96-Stream DMA Controller with Hardware Scatter/Gather PC/PCI & CCLS Legacy Parameter RAM Sample RAM Program RAM Program ROM Coefficient ROM SLIMD SP Core AC '97 2.0 Interface AC '97 2.0 Interface S/PDIF In S/PDIF Out MPU-401 MIDI Interface Joystick Interface PCI Bus PCI Interface ZV Port Async. Modem Interface 2 PI293PP1 JUL `98 CS4622/24 Overview Overview The CS4622/24 is a high performance audio accelerator DSP for the PCI bus. This device, combined with application and driver software, provides a complete system solution for cost effective acceleration of Windows DirectSound, Direct-Sound3D, DirectInput, MIDI playback via Wavetable Synthesis with reverberation and chorus effects processing, and more. The CS4622/24 is compatible with the CS4610C with the following added features: - Primary AC `97 Interface now 2.0 compatible - 2nd AC `97 Interface (also 2.0 compliant) - CrystalClear Legacy Support - PC/PCI Legacy Support - DDMA Legacy Support - PCI Power Management Event Support - ZV Port Asynchronous Serial Port - 2nd Asynchronous Serial Port - 9 Extended GPIO pins for Modem Support - Consumer Digital (S/PDIF) Input and Output The CS4622 is a high-performance, full-featured version of the SoundFusion audio accelerator. The CS4624 is a reduced-cost version of the CS4622. The CS4624 has a lower maximum clock speed and does not support AC-3. Please refer to the OEM Software Reference Manual for more details. FAQs 1) A: 2) A: What is the difference between the two devices? The CS4622 offers the capability to decode Dolby Digital (AC3), and the CS4624 does not. How is the Dolby License obtained? Cirrus Logic can only ship devices and software implementing Dolby PI293PP1 JUL `98 3 CS4622/24 Ordering Information technology to Dolby certified customers. A Dolby System License certification can be obtained by faxing a written request to Dolby Licensing Corporation, at (415) 863-1373. This request should include a description of the intended application and should be marked "Request for Dolby License Application". 3) A: How are these devices different than the other Crystal PCI audio products (CS4280 and CS4614)? The CS4280 does not offer DSP acceleration for wavetable synthesis and 3D sound, using the host processor instead. The CS4614 offers DSP processing, but not digital I/O (SPDIF) or ZVPort support. Which markets would the CS4622 and CS4624 serve? Manufacturers of PC motherboards, portables, and PCI audio cards would use the CS4622 and CS4624, where the performance advantages of DSP processing are desired along with the digital input/output to connect to high-end audio devices . The DSP processor is used for hardware wavetable synthesis and 3D audio acceleration for the games/multimedia market, and acoustic echo cancellation for speakerphone/ videoconferencing in the commercial market. 4) A: Ordering Information CS4622-CQ CS4624-CQ 128-pin TQFP 128-pin TQFP 20x14x1.60 mm 20x14x1.60 mm If you have any questions, please contact the undersigned by phone or by email.
