9DBL411BGILF

Overview

The 9DBL411BGILF is a four-output lower power differential buffer manufactured by Renesas Electronics Corporation. Designed for Intel QPI and PCI Express (PCIe) applications, it accepts HCSL input signals and provides LP-HCSL differential outputs. The device operates at a maximum frequency of 150MHz with a single circuit configuration. It functions within a supply voltage range of 3V to 3.6V and supports an operating temperature range of -40°C to 85°C. The component is housed in a 20-TSSOP package with a pitch of 0.65mm.

Feature Summary

• Four differential outputs with individual Output Enable (#OE) pins
• Supports Intel QPI and PCIe Gen1-2-3 fanout buffering
• Converts HCSL inputs to LP-HCSL differential signaling
• Maximum operating frequency of 150MHz

Applications

• Intel QuickPath Interconnect (QPI) clock distribution
• PCI Express (PCIe) system clock fanout
• CPU clock distribution networks

Procurement Notes

Verify the suffix 'GILF' corresponds to the 20-TSSOP package variant with industrial temperature rating (-40°C to 85°C). Confirm RoHS3 compliance status as per current manufacturer documentation. Check for any Product Change Notifications (PCN) regarding assembly sites or labeling changes that may affect long-term availability or pin compatibility.

Selection Notes

Select this model when a TSSOP footprint is required instead of the VFQFN alternative. Ensure the design accommodates the 3V to 3.6V supply voltage range. Verify that the 150MHz maximum frequency meets the specific bus speed requirements of the target PCIe or QPI implementation. Consider the thermal performance of the TSSOP package for the intended application environment.

Part Context

This component belongs to the 9DBL411 family of low-power differential buffers. It serves as a signal integrity solution for high-speed serial interfaces. The 'B' designation typically indicates the 150MHz frequency variant, distinguishing it from higher-speed models like the 9DBL411A. The 'GI' suffix specifies the TSSOP package and industrial temperature grade.

Replacement Considerations

The 9DBL411BGLFT is a direct equivalent offering the same electrical specifications and TSSOP package but with a commercial temperature range (0°C to 70°C). For designs requiring the wider industrial temperature range, no direct cross-package substitute is listed in the provided data.
