9DBV0741AKILFT

Overview

The 9DBV0741AKILFT is a 7-output, 1.8V PCIe fanout clock buffer from Renesas Electronics. It features integrated terminations for direct connection to 100-ohm transmission lines, eliminating the need for external resistors. The device supports HCSL differential inputs and LP-HCSL outputs, operating within a frequency range of 1 MHz to 200 MHz. It includes seven output enable pins for power management and three selectable SMBus addresses for configuration. The component is housed in a space-saving 5x5 mm 32-pin VFQFPN package with an exposed pad.

Feature Summary

• Seven differential outputs with integrated 100-ohm terminations
• HCSL-compatible differential input supporting spread spectrum
• Individual output enable (OE#) pins for DIF power management
• SMBus interface with selectable addresses for feature optimization

Applications

• PCI Express Gen 1 through Gen 5 clock distribution
• High-performance computing systems requiring low jitter
• Server and storage infrastructure clocking networks

Procurement Notes

Verify the specific suffix 'AKILFT' against official Renesas documentation to confirm packaging details and RoHS compliance status. Ensure the source document explicitly lists this part number, as family datasheets may group multiple variants. Confirm moisture sensitivity level and reel quantity specifications directly from the manufacturer's data sheet before procurement.

Selection Notes

Select the 9DBV0741AKILFT when seven independent clock outputs are required for PCIe applications. Verify that the system requires 1.8V core voltage and HCSL signaling compatibility. Consider the 32-pin VFQFPN package dimensions for board space constraints. Ensure the design utilizes the integrated terminations to reduce component count compared to standard HCSL buffers.

Part Context

This component belongs to the Renesas 9DBV05x1/07x1/09x1 family of PCIe fanout clock buffers. These devices are designed for high-speed serial link applications compliant with PCIe standards. The family shares common architectural features such as SMBus control and integrated termination resistors, differing primarily in output count and specific electrical characteristics.

Replacement Considerations

Direct replacements within the same family include the 9DBV0541 (5 outputs) or 9DBV0941 (9 outputs), provided pin compatibility and output count requirements allow. Verify that any substitute maintains the 1.8V supply voltage and LP-HCSL output signaling. Cross-reference package dimensions if mechanical fit is critical.
