9FGL0451CKILFT

Overview

The Renesas 9FGL0451CKILFT is a single-output clock generator designed for PCI Express (PCIe) applications. It operates with a maximum frequency of 100MHz and accepts crystal or clock inputs. The device features HCSL and LVCMOS output signaling types, supporting a 1:2 input-to-output ratio. It functions within a supply voltage range of 3.135V to 3.465V and supports an operating temperature range from -40°C to 85°C. The component is housed in a 24-VFQFN package with exposed pads, measuring 4x4mm.

Feature Summary

• Single-output PCIe clock generator with 100MHz maximum frequency
• Supports HCSL and LVCMOS output signaling formats
• Operates on 3.3V nominal supply (3.135V–3.465V)
• Available in compact 24-QFN (4x4mm) surface-mount package

Applications

• PCI Express interface clock generation
• System timing for high-speed digital circuits
• Industrial equipment requiring precise clock signals

Procurement Notes

Verify the specific suffix CKILFT against official Renesas documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint for the 24-VFQFN package. Confirm moisture sensitivity level requirements during assembly processes. Check for any recent lifecycle status updates directly from the manufacturer.

Selection Notes

Select this component when a single differential or single-ended output is required for PCIe designs. Compare output impedance and jitter specifications against system requirements. Consider the 24-QFN package size constraints relative to available board space. Verify that the 100MHz frequency limit meets the design's maximum clock speed needs.

Part Context

This part belongs to the 9FGL0451 series of clock generators from Renesas. The series includes variants with different output counts and packaging options. The CKILFT suffix typically denotes specific tape-and-reel packaging and material compliance details defined by the manufacturer.

Replacement Considerations

Consult Renesas datasheets for direct cross-references within the 9FGL04xx family. Verify pin compatibility and electrical parameters before substituting with other manufacturers' PCIe clock buffers.
