9DBU0731AKILF

Overview

The 9DBU0731AKILF is a PCIe fanout clock buffer manufactured by Renesas Electronics Corporation. It provides seven outputs from a single differential input, operating at a maximum frequency of 167MHz with a supply voltage range of 1.425V to 1.575V. The device features an additive phase jitter of typically 0.31ps RMS and supports PCIe Gen1, Gen2, and Gen3 standards. It is housed in a 40-MLF package and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Provides seven output channels for clock distribution
• Supports multiple SMBus addresses for configuration
• Complies with PCIe Gen1, Gen2, and Gen3 jitter requirements

Applications

• PCI Express (PCIe) clock distribution networks
• High-speed data transmission systems requiring low jitter
• Server and storage infrastructure timing solutions

Procurement Notes

Verify the specific package variant and revision level against the official Renesas datasheet before procurement. Confirm that the application environment strictly adheres to the specified supply voltage and thermal operating ranges. Ensure compatibility with existing PCB layout constraints for the 40-MLF footprint to prevent integration issues during assembly.

Selection Notes

Select this component when a single differential clock source must drive seven downstream loads with minimal signal degradation. It is suitable for designs requiring compliance with strict PCIe jitter masks across multiple generations. Consider the low power consumption profile and the availability of multiple SMBus addresses for flexible system management and monitoring capabilities.

Part Context

This part belongs to the Renesas 9DBU series of PCIe clock buffers, designed specifically for high-performance computing applications. It complements other timing components like multiplexers and generators within the same ecosystem, ensuring coherent clock distribution across complex motherboard architectures while maintaining signal integrity standards.

Replacement Considerations

No direct public substitute part numbers are confirmed for this discontinued component. Evaluate alternative PCIe clock buffers from Renesas or other manufacturers based on pin compatibility, electrical specifications, and package dimensions to ensure functional equivalence in existing designs.
