9DBV0841AKILF

Overview

The 9DBV0841AKILF is a clock buffer manufactured by Renesas Electronics Corporation, designed for PCI Express applications. It features one differential input and eight differential outputs with an input-to-output ratio of 1:8. The device operates at a maximum frequency of 200 MHz and supports HCSL signaling standards for both input and output. It utilizes a 48-VFQFN package with dimensions of 6x6 mm. The component functions as a zero-delay or fanout buffer within the PCIe clock distribution network.

Feature Summary

• Eight differential LP-HCSL outputs for PCIe clock distribution
• Integrated 100-ohm terminations for direct connection to transmission lines
• Supports spread spectrum input for EMI reduction
• SMBus interface for selectable configuration and address assignment

Applications

• PCIe Riser Cards
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control and Embedded Systems

Procurement Notes

Verify the specific suffix 'AKILF' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Check for Product Change Notifications (PCNs) regarding assembly site changes or package revisions. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Selection Notes

Select this component when eight low-power LVPECL/HCSL compatible outputs are required from a single HCSL source. Ensure the design accommodates the 3.3V supply voltage typical for this family member. Verify that the 48-VFQFN footprint matches the PCB layout constraints and thermal requirements for the target application environment.

Part Context

This part belongs to the 9DBV05x1-07x1-09x1 family of PCIe fanout clock buffers. It shares architectural similarities with other members like the 9DBV0541 and 9DBV0941, differing primarily in the number of outputs. The family is characterized by integrated terminations and SMBus configurability for flexible system integration.

Replacement Considerations

Direct substitutes within the same family include the 9DBV0541 (5 outputs) or 9DBV0941 (9 outputs), provided the output count difference is acceptable. Cross-family replacements such as the 9DBL series should be evaluated for voltage level compatibility and pinout alignment.
