9DBV0531AKLF

Specialized Overview

The 9DBV0531AKLF is a clock generator and support product manufactured by Renesas Electronics. It functions as a 5-output, 1.8 V PCIe Gen1-2-3 fanout buffer. The device operates within the 9DBV0531 series and is categorized under Clock Generators in the Clock & Timer ICs subcategory. It features humidity sensitivity and is marked with the Renesas Electronics trademark. The component is supplied in a tray package format.

Specialized Feature Summary

• Supports PCIe Gen1, Gen2, and Gen3 standards via 1.8 V operation
• Provides five differential output channels for clock distribution
• Functions as a fanout buffer to replicate input clock signals

Specialized Applications

• PCI Express (PCIe) system clock distribution
• High-speed digital interface timing networks
• Server and storage backplane clocking

Specialized Procurement Notes

Verify the specific datasheet revision and Product Change Notification (PCN) status before integration. Confirm that the 490-unit factory packaging aligns with production volume requirements. Ensure compliance with RoHS directives and moisture sensitivity level classifications during storage and handling procedures.

Specialized Selection Notes

Select this component when a low-voltage 1.8 V fanout solution is required for PCIe Gen1 through Gen3 interfaces. Evaluate the five-output capacity against system topology needs. Consider the VFQFPN package dimensions for board space constraints compared to alternative pin counts in the 9DBV05x1 family.

Specialized Part Context

This part belongs to the Renesas 9DBV05x1 family of PCIe fanout buffers. It shares architectural similarities with variants like the 9DBV0541 and 9DBV0941, differing primarily in output count and specific electrical characteristics. The series targets high-performance computing applications requiring compliant PCIe clock generation.

Specialized Replacement Considerations

Direct substitutes within the same family include the 9DBV0541 and 9DBV0941. Verify pin compatibility and electrical parameter alignment before substitution. Cross-reference datasheets to ensure equivalent PCIe generation support and voltage levels.
