9DBV0931AKILFT

Overview

The 9DBV0931AKILFT is a PCIe clock buffer and fanout device manufactured by Renesas Electronics. It operates with a single supply voltage ranging from 1.7V to 1.9V and supports maximum frequencies up to 137.5MHz. The component features one differential HCSL input and four differential LP-HCSL outputs, providing a 1:4 fanout ratio. Packaged in a 32-VFQFN (5x5mm) with an exposed pad, it is designed for surface mount installation. The device functions within an operating temperature range of -40°C to +85°C and includes integrated PLL capabilities for clock generation and distribution in high-speed serial interface applications.

Feature Summary

• Provides 1:4 differential fanout from HCSL input to LP-HCSL outputs
• Supports PCIe Gen1 through Gen6 clocking architectures
• Integrated PLL for low-jitter clock synthesis
• Operates on a single 1.7V to 1.9V power supply

Applications

• PCI Express (PCIe) root complex clock distribution
• Switch fabric clock buffering
• High-speed data acquisition systems requiring precise timing

Procurement Notes

Verify the specific suffix 'AKILFT' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the 32-VFQFN package. Check for any recent product change notifications regarding material composition or manufacturing site updates before finalizing procurement orders.

Selection Notes

Select this component when a 1:4 fanout ratio is required for PCIe clock networks. The LP-HCSL output signaling reduces power consumption compared to standard HCSL. Verify that the system design accommodates the 1.7V-1.9V supply rail and that the 32-pin QFN package fits within the available board space constraints.

Part Context

This part belongs to the 9DBV09xx family of PCIe clock buffers. It serves as a fanout solution for distributing reference clocks to multiple downstream devices. The device complements other members of the family that offer different output counts or input/output configurations for varied system topology requirements.

Replacement Considerations

Direct replacements within the same family include parts with identical pinouts and electrical characteristics but potentially different output counts or packaging options. Verify functional equivalence regarding PLL bandwidth and jitter performance when substituting with other PCIe clock buffer ICs.
