9DBL0651CKILF

Overview

The 9DBL0651CKILF is a clock buffer manufactured by Renesas Electronics, belonging to the 9DBL0x series. It features six low-power HCSL (LP-HCSL) outputs and operates in fan-out mode with frequencies ranging from 1MHz to 200MHz. The device supports PCIe clock architectures, including Common Clock (CC) and Independent Reference (IR) modes with or without Spread Spectrum (SRIS/SRNS). It utilizes a 40-VFQFPN package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Six LP-HCSL outputs eliminate the need for external termination resistors on each output line.
• Supports PCIe Gen5 Common Clock jitter specifications (<60fs RMS in fan-out mode).
• Includes three selectable SMBus addresses for configuration flexibility.
• Features dedicated Output Enable (OE) pins for each individual output channel.

Applications

• PCIe adapter cards
• NVMe storage systems
• Network infrastructure equipment

Procurement Notes

Verify the specific suffix 'CKILF' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 40-VFQFPN package. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Selection Notes

Select this component when six differential LVPECL, LVDS, CML, or SSTL loads require driving via low-power HCSL signals. Verify that the input frequency falls within the 1MHz to 200MHz operational range. Consider the integrated 100Ω termination if required by the specific PCIe generation design constraints.

Part Context

This part belongs to the Renesas 9DBL0x family of low-power, high-performance fan-out buffers designed for PCIe Gen1 through Gen5 applications. It serves as a distribution IC for CPU and PCIe clock networks, offering space-saving packages compared to discrete resistor solutions.

Replacement Considerations

The 9DBL0641CKILF is a related model within the same family but provides only six outputs with different impedance characteristics. Verify pinout compatibility and electrical parameters before substituting.
