9DBL411BGILFT

Overview

The 9DBL411BGILFT is a low-power differential clock buffer manufactured by Renesas Electronics. It features one differential input and four differential outputs, supporting frequencies up to 150 MHz. The device accepts HCSL input signals and generates LP-HCSL output signals. It operates on a single 3 V to 3.6 V supply voltage and is housed in a 20-TSSOP package with a pitch of 0.65 mm. Each output includes an independent output enable pin for power management.

Feature Summary

• Four differential outputs with individual OE# pins
• HCSL input to LP-HCSL output conversion
• Maximum operating frequency of 150 MHz
• Single 3 V to 3.6 V supply voltage operation

Applications

• Intel QuickPath Interconnect (QPI) systems
• PCI Express (PCIe) fanout buffering
• Low-power clock distribution networks

Procurement Notes

Verify the specific suffix 'BGILFT' against the official datasheet to confirm the TSSOP package type and RoHS compliance status. Ensure the ordering code matches the manufacturer's current nomenclature, as suffixes may indicate packaging variations or material changes without altering electrical function.

Selection Notes

Select this component when a 1:4 differential fanout buffer is required for PCIe or QPI interfaces. It is suitable for designs needing HCSL-to-LP-HCSL translation within a 150 MHz bandwidth. Verify that the 20-TSSOP footprint fits the PCB layout constraints compared to alternative VFQFN packages in the same family.

Part Context

This part belongs to the 9DBL411 series of low-power differential buffers. It shares core specifications with variants like the 9DBL411BKILFT but differs primarily in the physical package configuration. The BGILFT designation specifically identifies the TSSOP housing option within the product line.

Replacement Considerations

The 9DBL411BKILFT serves as a functional equivalent within the same family, offering identical electrical performance in a 20-VFQFPN package. Cross-package substitution requires verifying mechanical fit and thermal characteristics.
