9DBU0541AKILFT

Overview

The 9DBU0541AKILFT is a PCI Express fanout clock buffer manufactured by Renesas Electronics Corporation. It features a single input to five output configuration with a maximum operating frequency of 167MHz. The device accepts HCSL and LVDS differential inputs and provides LP-HCSL differential outputs. It operates on a supply voltage ranging from 1.425V to 1.575V and functions within an ambient temperature range of 0°C to 70°C. The component is housed in a 32-VFQFN package with an exposed pad, specifically identified as a 32-VFQFPN (5x5) supplier device package.

• 1:5 Input-to-Output Ratio
• HCSL/LVDS Differential Input Support
• LP-HCSL Differential Output Signaling
• Integrated PLL-Free Architecture

Applications

• PCI Express Clock Distribution
• CPU Clock Fanout
• High-Speed Digital System Timing

Procurement Notes

Verify the specific suffix 'AKILFT' against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the 9DBU0541 family. Confirm RoHS3 compliance status for current production lots. Check for End-of-Life notifications or alternative part recommendations directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 1.5V PCIe compliant clock buffer with five outputs is required. Ensure the design supports LP-HCSL signaling levels at the receiving end. Verify that the input source can drive either HCSL or LVDS formats compatible with the device's input stage. Confirm thermal management requirements for the 32-pin VFQFPN package under maximum load conditions.

Part Context

This part belongs to the 9DBU0541 series of PCIe fanout buffers. It serves as a timing distribution solution for systems requiring multiple clock domains derived from a single source. The device is designed to meet the jitter and signal integrity specifications defined for PCI Express generations supporting up to 167MHz operation.

Replacement Considerations

Consult the official Renesas product selector for direct replacements within the 9DBU series. Verify pin compatibility and electrical parameter alignment if considering cross-family alternatives.
