9DBU0931AKILF

Overview

The 9DBU0931AKILF is a clock buffer manufactured by Renesas Electronics Corporation, designed for PCI Express applications. It features two outputs with an input-to-output ratio of 2:1. The device supports maximum input frequencies up to 167 MHz and operates on a supply voltage range of 1.425 V to 1.575 V. It utilizes HCSL inputs and generates LP-HCSL outputs. The component is housed in a VFQFPN-48 package and is rated for commercial temperature operation between 0°C and +70°C.

Feature Summary

• PCI Express compatible clock buffer with 2 outputs
• Supports PCIe Gen1, Gen2, and Gen3 standards
• Low power consumption of 56 mW typical
• Operates within 1.425 V to 1.575 V supply voltage

Applications

• PCI Express Gen1/Gen2/Gen3 clock distribution
• Server and storage system timing
• Industrial control systems requiring low-power clock buffering

Procurement Notes

This component has reached End-of-Life (EOL) status and is no longer in production. Verification of availability should focus on remaining stock from authorized distributors or secondary market sources. Buyers must confirm the specific revision level and ensure compliance with RoHS directives as indicated in the datasheet before procurement.

Selection Notes

Select this part for designs requiring a 2:1 differential clock buffer for PCIe interfaces operating at frequencies up to 167 MHz. Ensure the design environment stays within the 0°C to +70°C commercial temperature range. Verify that the PCB layout accommodates the VFQFPN-48 package dimensions and thermal requirements for the specified power dissipation.

Part Context

The 9DBU0931AKILF belongs to the 9DBU0931 series of clock buffers from Renesas. It is specifically engineered for high-speed serial interface timing, providing signal integrity for PCIe protocols. As an EOL product, it represents a legacy solution for older PCIe generations compared to newer multi-standard buffers.

Replacement Considerations

Renesas recommends the 9DBU0931BKLF as a manufacturer-recommended replacement. This alternative shares similar specifications but may include updated manufacturing processes or minor parameter adjustments. Engineers should review the electrical characteristics of the BKLF variant to ensure compatibility with existing designs.
