9FGL0241CKILFT

Overview

The Renesas 9FGL0241CKILFT is a PCIe Gen 1–6 compliant clock generator designed for high-performance computing applications. It features two differential LP-HCSL outputs and one LVCMOS REF output with Wake-On-LAN support, operating at a fixed 25MHz frequency. The device supports Common Clocked (CC), Separate Reference no Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. Integrated terminations for 100Ω and 85Ω systems reduce external component count. Each output includes a dedicated OE# pin for CLKREQ# functionality. Powered by a 3.3V supply, it operates within a temperature range of -40°C to 85°C in a compact 24-VFQFPN package.

Feature Summary

• PCIe Gen 1–6 CC-compliant with SRNS and SRIS clocking architecture support
• Integrated 100Ω and 85Ω termination resistors eliminate external components
• Pin-selectable spread spectrum: 0% (SRNS/CC) or -0.5% (CC/SRIS)
• SMBus-selectable -0.25% spread spectrum option available

Applications

• Servers and High-Performance Computing platforms
• NVMe Storage subsystems
• Networking Accelerators
• Industrial Control systems

Procurement Notes

Verify the obsolete status of this component before design finalization. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the 24-VFQFPN package dimensions match the PCB footprint requirements. Check for RoHS compliance documentation if required by specific regional regulations.

Selection Notes

Select this model when a 25MHz input reference is required for PCIe Gen 1–6 interfaces. Choose the 9FGL0241 over the 9FGL0251 if only two differential outputs are needed. Verify that the system requires integrated termination resistors to save board space. Ensure the application supports the specified 3.3V core voltage and LP-HCSL signaling levels.

Part Context

This part belongs to the 9FGL02xx series of 3.3V PCIe clock generators. It shares architectural similarities with the 9FGL0251 but differs in output count and specific configuration options. The CKILFT suffix indicates the specific package type, lead-free composition, and tape-and-reel packaging format used for surface-mount assembly.

Replacement Considerations

The 9FGL0251CKILFT is a related variant offering different output configurations. Direct substitution requires verifying that the target circuit utilizes only two differential outputs and matches the 25MHz input requirement. No other direct cross-model replacements are documented.
