9FGL0651BKILF

Overview

The 9FGL0651BKILF is a 6-output, 3.3V PCIe clock generator manufactured by Renesas Electronics Corporation (formerly IDT). Designed for PCI Express Gen 1 through Gen 6 compliance, it supports Common Clocked (CC), Separate Reference No Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. The device features integrated terminations for 100Ω and 85Ω systems, reducing external component count. It operates within a supply voltage range of 3.135V to 3.465V and utilizes a 24-VFQFPN package.

Feature Summary

• PCIe Gen 1–6 compliant with support for CC, SRNS, and SRIS clocking architectures
• Six differential LP-HCSL outputs with dedicated OE# pins supporting CLKREQ#
• Integrated terminations for 100Ω and 85Ω systems to save external resistors
• SMBus-selectable spread spectrum options: CC/SRIS -0.25% and pin-selectable -0.5%

Applications

• Servers and High-Performance Computing systems
• NVMe Storage solutions
• Networking Accelerators
• Industrial Control applications

Procurement Notes

Verify the current lifecycle status of the 9FGL0651BKILF, as sources indicate potential discontinuation or transition from the original manufacturer IDT to Renesas. Confirm package availability in the 24-VFQFPN format and ensure RoHS3 compliance matches specific project requirements before procurement.

Selection Notes

Select this component when designing for PCIe Gen 1–6 interfaces requiring six synchronized clock outputs. Ensure the design accommodates the 3.3V core voltage and LP-HCSL signaling levels. Verify that the 24-VFQFPN package dimensions (4mm × 4mm) fit the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the 9FGL02-04-06-08 series of PCIe clock generators. It shares architectural similarities with the 9FGL0241/51 devices but provides six outputs instead of two. The product line has transitioned from IDT to Renesas Electronics Corporation, maintaining compatibility with previous generations while updating manufacturing sources.

Replacement Considerations

For direct functional replacements within the same family, consider the 9FGL0241/51 series for lower output counts or other variants in the 9FGL0651 lineup. Verify pin-to-pin compatibility and electrical specifications against the updated Renesas datasheet.
