9DBL0242BKILFT

Overview

The 9DBL0242BKILFT is a 3.3V PCIe clock buffer manufactured by Renesas Electronics Corporation, designed for high-performance computing and networking applications. It features two differential outputs with Low Power HCSL (LP-HCSL) signaling, supporting frequencies from 1 MHz to 200 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V and includes integrated 100Ω termination resistors for direct connection to transmission lines. Packaged in a compact 4mm x 4mm 24-VFQFPN format, it supports spread spectrum clocking architectures including Common Clocked (CC), Separate Reference Independent Spread (SRIS), and Separate Reference No Spread (SRNS).

Feature Summary

• Integrates 100Ω termination resistors on each output pair to eliminate external components.
• Supports PCIe Gen 1 through Gen 5 Common Clocked and Independent Reference clocking architectures.
• Features dedicated Output Enable (OE#) pins for each output to support CLKREQ# functionality.
• Compatible with spread spectrum clocking to reduce electromagnetic interference.

Applications

• PCIe adapter cards
• NVMe storage systems
• Networking equipment
• Industrial control and embedded systems

Procurement Notes

Verify the specific suffix 'BKI' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with system requirements for LP-HCSL signaling and 100Ω termination. Confirm operating temperature ranges align with application constraints before procurement.

Selection Notes

Select this component when a low-pin-count solution is required for distributing PCIe reference clocks. The integrated 100Ω terminations simplify board layout compared to buffers requiring external resistors. Verify that the input frequency range of 1 MHz to 200 MHz matches the source clock generator capabilities.

Part Context

This part belongs to the Renesas 9DBL0x series of fan-out buffers, which are optimized for PCIe clock distribution. These devices provide low-power HCSL outputs and support various PCIe clocking architectures. The series is designed to replace discrete resistor networks and standard buffers in high-speed digital designs.

Replacement Considerations

Check for updated versions within the 9DBL0x family or alternative Renesas PCIe buffers with similar pin counts and termination configurations. Ensure any substitute maintains LP-HCSL output signaling and compatible supply voltage ranges.
