9FGL0451CKILF

Overview

The 9FGL0451CKILF is a single-output clock generator designed for PCI Express applications, manufactured by Renesas Electronics. It operates with a maximum frequency of 100 MHz and accepts crystal or clock inputs. The device features a 1:2 input-to-output ratio and supports HCSL and LVCMOS output signaling types. It functions within a supply voltage range of 3.135 V to 3.465 V and is rated for an operating temperature range of -40°C to +85°C. The component is housed in a 24-VFQFN package with exposed pads, measuring 4x4 mm.

Feature Summary

• Single-output architecture optimized for PCI Express timing requirements
• Supports HCSL and LVCMOS output signaling formats
• Integrated PLL for frequency synthesis from crystal or clock inputs
• Operates on a 3.135 V to 3.465 V power supply

Applications

• PCI Express interface clock generation
• Server and workstation motherboard timing circuits
• High-speed digital system synchronization

Procurement Notes

Verify the specific suffix 'CKILFT' against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Confirm current production status as components in this series may be subject to discontinuation notices. Ensure compatibility with existing PCB footprint designs for the 24-QFN package before procurement.

Selection Notes

Select this component when a single differential or single-ended output at frequencies up to 100 MHz is required for PCIe links. Compare against the 9FGL0451BKILF if four outputs are needed instead of one. Verify that the HCSL/LVCMOS output swing meets the receiver input specifications of the target application.

Part Context

This part belongs to the 9FGL0451 family of clock generators. It shares the core functionality with variants like the 9FGL0451BKILF but differs in output count and packaging configuration. The CKILFT designation indicates specific packaging and trailing zero options defined by the manufacturer.
