9FGL0651DKILF

Overview

The 9FGL0651DKILF is a 3.3V PCIe Gen1-5 clock generator providing six differential outputs. It supports Common Clocked (CC), Separate Reference Independent Spread (SRIS), and Separate Reference No Spread (SRNS) architectures. The device features integrated terminations for 100Ω and 85Ω systems, reducing external component count. Typical power consumption ranges from 112mW to 206mW at 3.3V, with an optional VDDIO rail allowing up to 35% power savings at 1.05V. Key specifications include 90fs RMS typical jitter for PCIe Gen5 CC mode, less than 50ps cycle-to-cycle jitter, and ±0ppm synthesis error.

Feature Summary

• Six 100MHz LP-HCSL differential outputs with dedicated OE# pins supporting PCIe CLKREQ# functionality.
• Supports PCIe Gen1-5 CC, SRIS, and SRNS clocking architectures with pin-selectable spread spectrum options.
• Integrated output terminations for both 100Ω and 85Ω systems save four resistors per output.
• Includes one 3.3V LVCMOS REF output with Wake-On-LAN (WOL) support.

Applications

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

Procurement Notes

Verify the specific suffix 'D' indicates the package type and configuration against the manufacturer's current ordering guide. Confirm that the 'KLF' suffix aligns with lead-free and RoHS compliance requirements for your region. Check for any recent Product Change Notifications (PCN) regarding assembly sites or material changes before finalizing procurement.

Selection Notes

Select this model when six differential PCIe clock outputs are required. Ensure the design utilizes the VDDIO rail if maximum power efficiency is needed, as it allows operation at 1.05V. Verify that the system requires PCIe Gen1 through Gen5 compliance rather than Gen6 or higher, which would necessitate a different family member.

Part Context

This component belongs to the 9FGL0x series of 3.3V PCIe clock generators. The '06' in the part number denotes the six-output variant within this family. Other variants include two, four, and eight-output versions, all sharing similar core functionalities but differing in pin counts and package dimensions.

Replacement Considerations

Direct replacements within the same family include the 9FGL0641DKILF for non-spread or different spread configurations. For systems requiring fewer outputs, the 9FGL0451DKILF may be suitable. For higher performance generations, consider the 9FGL06xxE series supporting PCIe Gen6.
