9DBV0531AKILFT

Specialized Overview

The 9DBV0531AKILFT is a 5-output, 1.8 V PCIe fanout clock buffer from Renesas Electronics. It supports PCIe Gen1-2-3 standards and features LP-HCSL differential outputs with integrated 100Ω terminations for direct transmission line connection. The device operates within a frequency range of 1 MHz to 200 MHz and consumes approximately 50 mW of typical power. It includes five output enable pins for clock management and three selectable SMBus addresses. The component is housed in a space-saving 5 mm x 5 mm 32-pin VFQFPN package.

Specialized Feature Summary

• Integrated 100Ω terminations eliminate external resistors and reduce board area.
• SMBus-selectable features allow optimization of signal integrity and EMI reduction via spread spectrum compatibility.
• Five independent output enable pins support dynamic power management strategies.

Specialized Applications

• PCIe Gen1-Gen3 system clock distribution
• High-performance computing server backplanes
• NVMe storage controller interfaces

Specialized Procurement Notes

Verify the specific suffix 'AKILFT' against official documentation to confirm tape-and-reel packaging and lead-free status. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target design environment before finalizing procurement orders.

Specialized Selection Notes

Select this component when a low-power, multi-output fanout solution is required for 1.8 V PCIe architectures. Consider the integrated termination feature for simplified PCB layout and reduced component count compared to standard HCSL buffers requiring external matching resistors.

Specialized Part Context

This part belongs to the 9DBV05x1 family of PCIe clock buffers. These devices are designed to replace multiple discrete components by integrating buffering, termination, and configuration capabilities into a single compact package suitable for dense high-speed digital designs.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing system clocks and ensure pin-to-pin equivalence if considering alternative vendors or updated series revisions.
