9DBL0242CKILFT

Overview

The Renesas 9DBL0242CKILFT is a low-power, high-performance clock buffer supporting PCIe Gen1 through Gen5. It features two Low Power HCSL (LP-HCSL) outputs with integrated 100Ω termination resistors, eliminating the need for external components. The device operates in fanout mode at frequencies from 1MHz to 200MHz and supports Common Clock (CC) and Independent Reference (IR) architectures with spread spectrum tolerance. It utilizes a 32-pin VFQFPN package and functions within a supply voltage range of 3.135V to 3.465V.

Feature Summary

• Two LP-HCSL outputs with integrated 100Ω termination resistors
• Supports PCIe Gen1-5 Common Clock and Independent Reference architectures
• Spread spectrum tolerant input capability
• Dedicated Output Enable (OE) pin for each output

Applications

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

Procurement Notes

Verify the specific suffix 'CKILFT' against official Renesas documentation to confirm packaging details such as reel size or tape width. Confirm RoHS compliance status directly with the manufacturer's datasheet. Ensure the ordering code matches the required package variant and moisture sensitivity level before procurement.

Selection Notes

Select this component when a dual-output PCIe clock buffer with integrated 100Ω termination is required. It is suitable for designs needing low power consumption and support for spread spectrum clocking. Verify that the 1MHz to 200MHz frequency range meets system requirements and that the 32-pin VFQFPN package fits the board layout constraints.

Part Context

This part belongs to the Renesas 9DBL0x series of fan-out buffers designed for PCIe applications. The series offers scalable output counts and integrated termination options to reduce bill-of-materials complexity. The 9DBL0242 variant specifically provides two outputs with 100Ω termination, distinguishing it from variants with different output counts or impedance values.

Replacement Considerations

Check for direct substitutes within the 9DBL0x family, such as the 9DBL0442 for four outputs or the 9DBL0252 for 85Ω termination. Ensure any replacement maintains compatibility with the target PCIe generation and spread spectrum requirements.
