9FGL0241DKILF

Application Specific Clock/Timing Overview

The Renesas 9FGL0241DKILF is a 3.3V PCIe Gen1-5 clock generator featuring two differential outputs and one LVCMOS REF output with Wake-On-LAN support. It operates at a maximum frequency of 100 MHz with a 25 MHz input. The device provides 90 fs RMS typical jitter for PCIe Gen5 Common Clocked architectures, cycle-to-cycle jitter under 50 ps, and ±0 ppm synthesis error. It utilizes a 24-VFQFPN package (4x4 mm) and supports integrated terminations for 85Ω and 100Ω systems.

Application Specific Clock/Timing Feature Summary

• Supports PCIe Common Clocked (CC), Independent Reference (IR), SRIS, and SRNS architectures.
• Integrated 100Ω and 85Ω output terminations reduce external component count.
• Differential outputs feature dedicated OE# pins supporting PCIe CLKREQ# functionality.
• SMBus-selectable features allow optimization of slew rate, amplitude, and impedance.

Application Specific Clock/Timing Applications

• Servers and High-Performance Computing
• NVMe Storage Systems
• Networking Equipment
• Accelerators
• Industrial Control

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'KILF' against official documentation to confirm lead-free status and tape-and-reel packaging details. Confirm that the 24-VFQFPN package dimensions match the design requirements. Ensure compatibility with the required SMBus interface voltage levels before procurement.

Application Specific Clock/Timing Selection Notes

Select this model for designs requiring exactly two differential PCIe clock outputs. Consider the 9FGL0441DKILF or higher variants if additional outputs are needed. Verify that the 3.3V supply requirement aligns with the system power architecture. Check thermal resistance specifications if operating in high ambient temperatures.

Application Specific Clock/Timing Part Context

This component belongs to the 9FGL02x1/04x1/06x1/08x1D family of 3.3V PCIe Gen1-5 clock generators. The family offers scalable output counts from 2 to 8 pairs. The 9FGL0241DKILF specifically represents the 2-output variant within this series, designed for space-constrained applications requiring low-power PCIe clocking.

Application Specific Clock/Timing Replacement Considerations

Direct replacements within the same family include the 9FGL0441DKILF (4 outputs) or 9FGL0641DKILF (6 outputs), provided pin compatibility and output requirements are assessed. Cross-family replacements may require schematic redesign due to differing pinouts and voltage levels.
