9DBL411AGLFT

Overview

The Renesas Electronics Corporation 9DBL411AGLFT is a CPU and PCI Express (PCIe) fanout buffer IC designed for signal distribution. It operates at a maximum frequency of 400MHz with one output channel. The device utilizes a 20-TSSOP package for surface mount installation. It accepts HCSL input signals and provides LP-HCSL output signaling. The component supports spread spectrum input specifications, making it suitable for high-speed digital applications requiring precise clock distribution within defined voltage and thermal limits.

Feature Summary

• Supports CPU and PCI Express (PCIe) fanout buffer applications
• Operates at a maximum frequency of 400MHz
• Accepts HCSL input and provides LP-HCSL output signaling
• Supports spread spectrum input specifications

Applications

• CPU clock distribution systems
• PCI Express (PCIe) signal routing
• High-speed digital board design

Procurement Notes

Verify the specific suffix GLFT against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with target operating temperatures and voltage levels. Confirm RoHS3 compliance status through current datasheets. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate that the single-output configuration meets system requirements before procurement.

Selection Notes

Select this component when a 400MHz fanout buffer is required for PCIe or CPU architectures. The HCSL to LP-HCSL conversion capability ensures signal integrity in high-speed environments. Consider the 20-TSSOP package constraints for PCB layout. Verify that the single-output topology aligns with the specific circuit design needs rather than multi-channel alternatives.

Part Context

The 9DBL411 series includes variants like the 9DBL411BGLF which support four outputs and lower frequencies up to 150MHz. The 9DBL411AGLFT specifically targets higher frequency operations at 400MHz with a single output. This distinction allows designers to choose between channel count and speed based on application demands within the same product family.
