CS4614-CM - PCI Audio Signal Processor | Cirrus Logic
MPN： CS4614-CM ✗ 停產CS4614-CM 概覽
An audio signal processor is a specialized integrated circuit that executes audio algorithms in real time. Within the broader hierarchy of audio codecs, DSP processors, sound processors, and signal-processing semiconductors, it combines host-interface functions with dedicated synthesis and effects processing. The CS4614-CM specifically targets PCI audio subsystems and adds legacy compatibility modes for real-mode DOS-oriented designs.
The CS4614's defining features include its 255-MIPs SLIMD DSP engine, DirectX 5.0 3D positional-audio support, and 64-voice wavetable synthesis with effects. Its package dimensions of 20 x 14 x 3.07 mm are suitable for compact PCI audio adapter designs, although the 100-lead footprint requires careful high-density PCB layout and reliable access to all external connections.
Technically, the device is described as a high-performance, pin-compatible upgrade to the 100-pin CS4610 and CS4611 PCI audio accelerators. This relationship is important for legacy system design because it indicates a shared 100-pin hardware boundary while allowing the CS4614 to add compatibility modes and more advanced processing capabilities.
Typical uses include legacy PCI audio cards, DOS-compatible multimedia computers, and retro gaming systems requiring positional audio, wavetable synthesis, and real-time effects. Its 64-voice synthesis capability supports more simultaneous voices than basic mono audio paths, while the SLIMD architecture provides the processing throughput required by DirectX-era sound engines.
Designers should preserve the CS4610 and CS4611-compatible PCB footprint and validate every signal, power, and ground assignment against the manufacturer datasheet before substitution. The supplied data does not include the complete electrical limits, clock requirements, analog interface details, or exhaustive pin definitions, so those values must be confirmed before layout or production use.
This page consolidates verified distributor availability, the manufacturer's published feature summary, package information, legacy upgrade context, and same-family migration guidance. It also distinguishes documented drop-in-family relationships from unsupported cross-brand equivalents and highlights the data still required for a complete hardware design review.

典型應用
CS4614-CM 適用於 6 應用s: Legacy PCI Gaming Sound Cards, DOS-Compatible Multimedia Systems, DirectX Positional Audio, Wavetable Music Synthesis, Industrial PCI Audio Control, Retro Computer Audio Restoration.
Legacy PCI Gaming Sound Cards
The CS4614-CM fits a legacy PCI gaming sound card because its 255-MIPs SLIMD DSP architecture provides dedicated processing for DirectX 5.0 three-dimensional positional audio. The processor is placed between the PCI host interface and the card's audio-routing circuitry, allowing game audio effects and spatialization to run without relying entirely on host CPU resources. Its 64-voice synthesis capability also supports multi-voice game sequences. A 100-pin MQFP footprint with 20 x 14 mm body dimensions must match the existing board, while the 3.07 mm package height requires clearance during enclosure and cooler installation.
推薦
DOS-Compatible Multimedia Systems
The CS4614-CM is specifically relevant to DOS-compatible multimedia systems because the manufacturer states that its added legacy compatibility modes enable real-mode DOS-compatible PCI-only audio subsystems. It can serve as the PCI audio engine in an industrial, scientific, or retro-computing system that must reproduce period-correct audio behavior while retaining a modern PCI host interface. The 255-MIPs SLIMD architecture supplies the throughput for synthesis and effects, but firmware, PCI enumeration, interrupt handling, and legacy mode configuration must be validated on the target platform.
推薦
DirectX Positional Audio
DirectX positional-audio workloads align with the CS4614-CM because its 255-MIPs SLIMD DSP architecture and documented DirectX 5.0 support are intended for real-time three-dimensional sound processing. In a legacy PC or industrial terminal, the device can execute spatial-audio algorithms and reduce host-processor demand while the motherboard provides the PCI bus and command interface. The 64-voice limit and wavetable-with-effects capability should be checked against the application's channel and voice count. Driver support, sample-rate handling, and synchronization behavior require validation against the manufacturer datasheet.
推薦
Wavetable Music Synthesis
The CS4614-CM can implement wavetable music synthesis because the manufacturer identifies support for 64-voice wavetable synthesis with effects. This makes it applicable to legacy game consoles, industrial demonstration systems, and audio cards designed to reproduce multitimbral soundfonts. The processor handles simultaneous voices and real-time effects through its 255-MIPs SLIMD DSP engine, reducing the operational burden on a host CPU compared with a software-only implementation. Designers must confirm sample-memory interfaces, clocking, output routing, and the exact synthesis feature set from the manufacturer datasheet before adapting a circuit.
推薦
Industrial PCI Audio Control
CS4614-CM may be used in industrial PCI audio-control equipment where a deterministic PCI interface and dedicated real-time processing are required. Its single-channel classification and legacy compatibility modes can suit specialized test, monitoring, or communication equipment built around older PCI infrastructure rather than modern USB audio. The 255-MIPs SLIMD architecture provides dedicated DSP throughput, but long-term product design requires careful validation of operating temperature, supply rails, clock stability, and driver support. The 100-pin surface-mount package also demands a robust assembly and inspection process.
推薦
Retro Computer Audio Restoration
The CS4614-CM is useful when restoring or recreating a PCI-based audio subsystem for vintage computing hardware. The documented pin compatibility with the CS4610 and CS4611 can simplify comparison of original boards, while the added legacy modes support real-mode DOS operation. A restoration engineer should remove and inspect aged devices, verify continuity, compare all 100 PCB connections, and confirm that replacement behavior matches the original accelerator. Because the part is a legacy processor, supplier provenance and component condition are especially important for maintaining a working museum, demonstration, or competition system.

主要差異化特點
- Adds legacy operating modes to a 100-pin PCI audio accelerator family (對比CS4610)
- Provides a documented 255-MIPs SLIMD DSP engine (對比CS4611)
- Combines synthesis and positional-audio functions in one processor (對比CS4610)
設計說明
Treat the CS4614-CM as a pin-compatible upgrade rather than an unconditional substitute. The manufacturer explicitly compares it with the 100-pin CS4610 and CS4611, so a reused PCB must be checked against the CS4614 electrical and pin documentation, especially power, ground, reset, clock, PCI, and audio connections. Confirm the exact 20 x 14 mm MQFP land pattern and exposed or underside thermal requirements before ordering replacement boards.
Do not assume that equal pin count guarantees identical firmware or signal behavior. The CS4614 adds legacy compatibility modes intended for real-mode DOS-compatible PCI-only audio subsystems, while the supplied data does not quantify the corresponding behaviors of CS4610 or CS4611. Validate PCI configuration, interrupt handling, driver compatibility, DMA behavior, audio timing, and sample-rate support on the complete system.
The verified package dimensions are 20 x 14 x 3.07 mm, but the supplied data does not provide power dissipation, junction-temperature limits, or package thermal resistance. Consequently, no thermal rise can be calculated without inventing inputs. For a new assembly, obtain the manufacturer power and thermal data, use the PCB's available copper area, and verify junction temperature and adjacent-component heating under maximum workload.
A 100-pin MQFP at 20 x 14 mm requires a dense, escape-routed layout and careful fanout from the package perimeter. Follow the manufacturer's reference design and package drawing for pad geometry, pin numbering, via construction, and assembly clearances. Because the verified pin list is unavailable, do not infer connections from board artwork alone; cross-check every net against the official pin table before fabrication.
合規資訊
The supplied verified results do not contain RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for CS4614-CM. AEC-Q100 is marked not applicable because this is a legacy PCI audio processor rather than an automotive-qualified device, but no automotive qualification claim is made.
