9DBL0951BKILFT

Overview

The 9DBL0951BKILFT is a PCI Express (PCIe) fanout clock buffer manufactured by Renesas Electronics Corporation. It supports PCIe Gen 1 through Gen 4 standards and operates with a single output configuration at a maximum frequency of 200MHz. The device utilizes a 48-VFQFPN (6x6) surface-mount package and functions within a supply voltage range of 3.135V to 3.465V. It features an input type of HCSL and provides differential output signals, also in HCSL format. The component is designed for applications requiring precise clock distribution in high-speed serial link environments.

Feature Summary

• Supports direct connection to 100-ohm or 85-ohm transmission lines, eliminating the need for external series resistors typically required in standard PCIe designs.

Applications

• PCI Express Gen 1 clock distribution
• PCI Express Gen 2 clock distribution
• PCI Express Gen 3 clock distribution

Procurement Notes

Verify the specific suffix 'BKILFT' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Check for any Product Change Notifications (PCNs) regarding package revisions or assembly site changes that may affect mechanical fit or material composition. Ensure the source document explicitly confirms the 48-VFQFPN package dimensions and thermal characteristics for your PCB layout requirements.

Selection Notes

Select this component when designing systems requiring a single-output PCIe clock buffer compatible with Gen 1 through Gen 4 speeds. It is suitable for applications where direct termination to 85-ohm or 100-ohm traces is desired to reduce bill-of-materials complexity. Consider the 48-VFQFPN package size constraints and the 3.3V nominal supply voltage requirement during the schematic capture phase.

Part Context

This part belongs to Renesas' 3.3V full-featured PCIe clock family, specifically designed for fanout buffering. It complements other devices like the 9DBL0841 series but differs in output count and specific impedance matching capabilities. The 9DBL0951 series addresses the need for simplified board layouts in high-speed interface designs by integrating termination resistance internally.

Replacement Considerations

Public confirmed substitute: 9DBL0951CKILFT. Verify if the 'C' suffix indicates a minor revision change in packaging or testing parameters before substitution.
