9FGL0641BKILFT

Overview

The 9FGL0641BKILFT is a six-output, 3.3V PCIe Gen 1–6 clock generator manufactured by Renesas Electronics. It supports Common Clocked (CC), Separate Reference Independent Spread (SRIS), and Separate Reference No Spread (SRNS) architectures. The device features pin-selectable spread spectrum levels of 0%, -0.5%, and SMBus-selectable -0.25%. Each output includes a dedicated OE# pin for CLKREQ# functionality and integrated terminations for 100Ω and 85Ω systems. It operates within a temperature range of -40°C to +85°C and utilizes a 24-VFQFPN package.

Feature Summary

• Supports PCIe Gen 1–6 CC, SRIS, and SRNS clocking architectures
• Six differential LP-HCSL outputs with integrated 100Ω/85Ω terminations
• Pin-selectable spread spectrum: 0%, -0.5%; SMBus-selectable -0.25%
• Dedicated OE# pins per output supporting PCIe CLKREQ# functionality

Applications

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

Procurement Notes

Verify the specific suffix 'BKILFT' against official Renesas documentation to confirm package type, tape-and-reel specifications, and RoHS compliance status. Ensure that the required spread spectrum configuration matches the available pin-selectable or SMBus-selectable options defined in the datasheet before finalizing procurement.

Selection Notes

Select this component when designing for PCIe Gen 1 through Gen 6 interfaces requiring up to six synchronized clock outputs. It is suitable for applications needing integrated termination resistors to reduce board space. Verify that the system requires 3.3V operation and LP-HCSL signaling levels compatible with the target receivers.

Part Context

This part belongs to the 9FGL02-04-06-08 family of PCIe clock generators. These devices are designed to replace discrete clock generation solutions by integrating multiple outputs and termination resistors into a single compact 4mm × 4mm 24-VFQFPN package, simplifying layout for high-speed serial links.

Replacement Considerations

Direct replacements within the same family include the 9FGL0241, 9FGL0441, and 9FGL0841, which offer two, four, or eight outputs respectively while maintaining identical electrical characteristics and pinouts where applicable.
