9DBU0531AKLF

Overview

The Renesas Electronics 9DBU0531AKLF is a clock generator and support product designed for PCIe Gen1-2-3 applications. It features five outputs operating at 1.8V. The device functions as a fanout buffer, distributing clock signals with low skew characteristics suitable for high-speed digital interfaces. It supports differential input and output configurations, ensuring signal integrity in demanding computing environments.

Feature Summary

• Five-output configuration for PCIe Gen1-2-3 systems
• Operates at 1.8V supply voltage
• Supports differential HCSL/LVDS-like signaling standards
• Low skew distribution for synchronized data paths

Applications

• PCI Express (PCIe) Gen1/Gen2/Gen3 clock distribution
• Server and workstation motherboard clocking
• High-performance computing platforms requiring multi-lane synchronization

Procurement Notes

Verify RoHS compliance status through official datasheets before integration. Confirm moisture sensitivity level (MSL) ratings to ensure proper handling during surface mount assembly processes. Check for any recent Product Change Notifications (PCN) regarding package revisions or material updates that may affect long-term supply chain stability.

Selection Notes

Select this component when a 1.8V powered, five-channel fanout buffer is required for PCIe generation 1 through 3 interfaces. Ensure the design accommodates the specific input/output voltage levels and differential signaling requirements. Compare against similar models like the 9DBU0541AKILF if different voltage or pin count specifications are needed.

Part Context

This part belongs to the 9DBU series of clock generators from Renesas Electronics. It is specifically engineered for PCI Express ecosystem timing solutions. The 'AKLF' suffix typically denotes a lead-free, halogen-free tray-packaged variant compliant with environmental directives.

Replacement Considerations

Consult official substitution guides for direct replacements. Similar family members such as the 9DBU0541AKILF offer comparable functionality but may differ in voltage or package type. Verify electrical compatibility before swapping components in existing designs.
