CS4614-CM

Audio Special Purpose Overview

The CS4614-CM is a high-performance audio signal processor designed as a pin-compatible upgrade to the 100-pin CS4610/11 PCI audio accelerators. It features a 255 MIPs SLIMD DSP architecture and supports AC '97 2.0 link codec interfaces. The device provides hardware acceleration for Microsoft DirectSound, DirectInput, and Wavetable Synthesis. Operating within a voltage range of 3V to 3.6V or 4.75V to 5.25V, it utilizes a 100-BQFP package (100-MQFP 20x14) and functions in commercial temperatures from 0°C to 70°C.

Audio Special Purpose Feature Summary

• 255 MIPs SLIMD DSP Architecture
• AC '97 2.0 Link Codec Interface
• PCI 2.1 Compliant with Power Management
• Hardware Sample Rate Conversion with 90+ dB Dynamic Range

Audio Special Purpose Applications

• Windows 95/98 DirectSound Hardware Acceleration
• DirectInput Joystick Interface Systems
• MPU-401 MIDI Input/Output Applications

Audio Special Purpose Procurement Notes

Verify the specific suffix '-CM' against manufacturer documentation to confirm package type and temperature grade alignment. Ensure compatibility with AC '97 codecs and PCI bus requirements before procurement.

Audio Special Purpose Selection Notes

Select this component for legacy PCI audio subsystems requiring DOS real-mode compatibility alongside modern Windows acceleration. Confirm that the system design supports the required 3.3V power supply with 5V tolerant I/O levels.

Audio Special Purpose Part Context

This part belongs to the Cirrus Logic CrystalClear SoundFusion series, serving as a successor to the CS4610 and CS4611 models. It integrates DSP capabilities with PCI interface logic to handle complex audio processing tasks in desktop computing environments.

Audio Special Purpose Replacement Considerations

The CS4610 and CS4611 are direct pin-compatible predecessors. Verify driver support availability for the target operating system when substituting these legacy components.
