9DBU0931AKILFT

Overview

The 9DBU0931AKILFT is a clock buffer manufactured by Renesas Electronics, designed for PCI Express applications. It features two LP-HCSL outputs driven by an HCSL input, supporting a maximum frequency of 167 MHz. The device operates on a 1.425 V to 1.575 V supply voltage and is housed in a 48-VFQFPN package with exposed pads. It supports differential input and output configurations.

Feature Summary

• Two-output configuration with LP-HCSL output type
• Maximum operating frequency of 167 MHz
• Low power consumption with 6 mA operating current
• Supports differential HCSL input and LP-HCSL output

Applications

• PCI Express Gen1-Gen3 systems
• Clock distribution networks requiring low power
• High-speed digital interface buffering

Procurement Notes

Verify the component status as the source data indicates it may be discontinued or have limited availability. Confirm the specific suffix 'AKILFT' matches the required packaging and environmental specifications against the official datasheet before procurement.

Selection Notes

Select this component when a two-channel PCIe clock buffer with LP-HCSL outputs is required. Ensure the design accommodates the 1.5 V nominal supply voltage and the 48-pin VFQFPN footprint. Verify thermal requirements given the 47 mW power dissipation at commercial temperatures.

Part Context

This part belongs to the 9DBU0931 series of zero-delay buffers from Renesas. It is functionally related to other members like the 9DBU0941 but offers a specific 1:2 fan-out ratio compared to higher channel counts in the family.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate other 9DBU series variants if pin compatibility allows, though output count differences must be addressed.
