9FGL0641DKILF

Overview

The Renesas 9FGL0641DKILF 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. Key electrical specifications include a typical jitter of 90fs RMS for PCIe Gen5 CC, less than 50ps cycle-to-cycle jitter, and zero ppm synthesis error. The device operates within a -40°C to +85°C temperature range using a 25MHz input frequency.

Feature Summary

• Supports PCIe Gen1-5 CC, SRIS, and SRNS clocking architectures
• Integrated terminations for 100Ω and 85Ω systems
• Pin-selectable spread spectrum: SRNS 0%, CC 0%, CC/SRIS -0.5%
• SMBus-selectable CC/SRIS -0.25% spread
• Dedicated OE# pins supporting PCIe CLKREQ# functionality

Applications

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

Procurement Notes

Verify the specific suffix 'KILF' against the manufacturer's official ordering guide to confirm packaging details such as reel quantity and tape type. Confirm RoHS compliance status directly with the supplier documentation prior to procurement.

Selection Notes

Select this component for designs requiring six independent PCIe reference clocks. Ensure the system utilizes a 25MHz crystal or LVCMOS input. Verify that the required output impedance matches the available 85Ω or 100Ω integrated termination options.

Part Context

This part belongs to the 9FGL0x1D family of 3.3V PCIe clock generators. Other members in this series include the 9FGL0241D (2 outputs), 9FGL0441D (4 outputs), and 9FGL0841D (8 outputs). All share similar core features but differ in pin count and package size.

Replacement Considerations

Direct replacements within the same family include the 9FGL0641AKILF or 9FGL0651DKILF. Verify that the alternative variant supports the required PCIe generation and spread spectrum settings.
