9FGL0841DKILFT

Overview

The Renesas Electronics 9FGL0841DKILFT is a 3.3V PCIe Gen1-5 clock generator featuring eight differential outputs and one LVCMOS REF output with Wake-On-LAN support. It operates at a nominal frequency of 100MHz with a 25MHz input requirement, housed in a 6x6mm 48-VFQFPN package. The device supports Common Clocked (CC), Independent Reference (IR), SRIS, and SRNS architectures. Key electrical specifications include 90fs RMS typical jitter for PCIe Gen5 CC, less than 50ps cycle-to-cycle jitter, and integrated terminations for 100Ω and 85Ω systems.

Feature Summary

• Supports PCIe Gen1 through Gen5 clocking architectures including CC, SRIS, and SRNS.
• Features eight differential LP-HCSL outputs and one 3.3V LVCMOS REF output with WOL.
• Includes integrated 100Ω and 85Ω output terminations to reduce external component count.
• Provides SMBus-selectable features such as slew rate, amplitude, and impedance configuration.

Applications

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

Procurement Notes

Verify the specific suffix 'D' indicates the die shrink revision compared to standard variants. Confirm package dimensions match the 6x6mm 48-VFQFPN footprint. Ensure design compatibility with 3.3V supply rails and 25MHz reference inputs before procurement.

Selection Notes

Select this model for designs requiring eight differential clock outputs compliant with PCIe Gen5 standards. Verify that the system utilizes a 25MHz crystal or reference clock input. Consider the VDDIO rail optimization if power savings are required for the differential outputs.

Part Context

This component belongs to the 9FGL02x1/04x1/06x1/08x1D family of 3.3V PCIe clock generators. The '08' designation specifies the eight-output variant within this series, sharing pinouts and functionality with the 2, 4, and 6-output versions while utilizing the larger 48-pin package.

Replacement Considerations

The 9FGL0841CKILFT is a confirmed public substitute within the same family. Verify pin compatibility and electrical parameters when substituting.
