ICS94201DFLF

Overview

The ICS94201DFLF is a programmable frequency generator and multiplexer IC designed for Intel CPU server applications. It features a single clock circuit with crystal input and clock output, operating at a maximum frequency of 500.03MHz. The device utilizes a 2:29 input-to-output ratio and lacks differential signaling. It functions within a supply voltage range of 3.135V to 3.465V and supports surface mount installation in a 56-SSOP package. The component operates reliably across an industrial temperature range of 0°C to 70°C.

Feature Summary

• Programmable frequency generator optimized for Intel CPU servers
• Single circuit configuration with 500.03MHz maximum frequency
• Crystal input interface with 2:29 input-to-output ratio
• Operates on 3.135V to 3.465V supply voltage

Applications

• Intel CPU server clock generation

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with existing crystal oscillators and power supply rails within the specified 3.135V to 3.465V range. Confirm that the 56-SSOP footprint matches the target PCB design requirements before procurement.

Selection Notes

Select this component when designing for Intel CPU server platforms requiring a single programmable clock output up to 500.03MHz. The 2:29 ratio and crystal input are critical constraints; ensure the system oscillator aligns with these parameters. Verify that the non-differential output meets the downstream logic requirements and that the 0°C to 70°C operating range suits the environmental conditions.

Part Context

This part belongs to Renesas' family of application-specific clock and timing solutions. It serves as a dedicated frequency generator for high-performance computing environments, specifically targeting Intel-based server architectures. The device integrates PLL functionality to generate stable clock signals from a crystal reference.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas portfolio that offer similar frequency ranges and package dimensions. Verify if newer revisions maintain the same 56-SSOP form factor and electrical specifications.
