9DBV0541AKILFT

Overview

The 9DBV0541AKILFT is a five-output, 1.8V PCIe fanout clock buffer manufactured by Renesas Electronics. It operates within a frequency range of 1MHz to 200MHz and features LP-HCSL differential outputs with integrated 16 termination resistors for direct connection to 100Ω transmission lines. The device supports spread spectrum input for EMI reduction and includes five output enable pins for clock management. It utilizes a space-saving 32-pin VFQFPN package (5mm x 5mm) and offers three selectable SMBus addresses for configuration optimization.

Feature Summary

• Five differential LP-HCSL outputs with integrated 100Ω terminations
• Operating frequency range from 1MHz to 200MHz
• Supports spread spectrum input for EMI reduction
• Three selectable SMBus addresses for system integration

Applications

• PCI Express adapter cards
• NVMe storage systems
• Network infrastructure equipment
• Industrial control and embedded systems

Procurement Notes

Verify the specific suffix 'AKILFT' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Note that Renesas timing products are transitioning to SiTime; ensure the component source is authorized and check for any product change notifications regarding packaging or manufacturing sites before finalizing procurement.

Selection Notes

Select this component when a low-power, high-performance PCIe clock distribution solution is required for Gen1 through Gen5 applications. The integrated 100Ω terminations reduce external component count and board space compared to standard HCSL buffers. Ensure the design requires five differential outputs and operates within the 1.8V supply voltage constraint.

Part Context

This part belongs to the 9DBV05x1-9DBV07x1-9DBV09x1 family of PCIe fanout clock buffers. It shares architectural similarities with other members of the series, differing primarily in the number of outputs and package options. The device is designed to replace discrete resistor networks in PCIe clock trees, simplifying layout and improving signal integrity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing output drive strength, jitter performance, and SMBus address configurations with alternative Renesas or third-party PCIe clock buffers.
