9DBU0731AKILFT

Overview

The 9DBU0731AKILFT is a PCI Express (PCIe) zero-delay fanout buffer manufactured by Renesas Electronics Corporation. It supports PCIe Gen1, Gen2, and Gen3 standards with a maximum operating frequency of 167MHz. The device features one circuit with a 1:7 input-to-output ratio, converting differential HCSL inputs to seven differential LP-HCSL outputs. It operates on a supply voltage range of 1.425V to 1.575V and functions within a temperature range of -40°C to 85°C. The component is housed in a 40-VFQFN package with an exposed pad.

Feature Summary

• Provides strong signal buffering for high-speed data transmission applications
• Engineered specifically for rigorous PCI Express Gen1-2-3 system demands
• Features ultra-low-power design capabilities for efficient operation

Applications

• PCI Express (PCIe) clock distribution networks
• High-speed data transmission systems requiring signal integrity
• Server and storage infrastructure clocking solutions

Procurement Notes

Verify the specific suffix 'AKILFT' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 40-VFQFPN(5x5) form factor. Confirm that the 1.5V supply requirements align with the target system design before procurement.

Selection Notes

Select this component when a single differential input must be distributed to seven outputs for PCIe Gen1-2-3 interfaces. It is suitable for designs requiring low skew and zero-delay buffering. Consider the 40-VFQFN package constraints and thermal dissipation needs for the exposed pad configuration during layout planning.
