9DBL0242BKILF

Overview

The 9DBL0242BKILF is a dual-output, 3.3V PCIe clock buffer manufactured by Renesas Electronics. It supports PCIe Gen 1 through Gen 6 architectures and operates within a frequency range of 1 MHz to 200 MHz. The device features Low Power HCSL (LP-HCSL) differential outputs with integrated 100Ω termination resistors, enabling direct connection to transmission lines without external components. It accepts spread spectrum inputs and offers configurable operation via an SMBus interface or pin selection.

Feature Summary

• Dual LP-HCSL outputs with integrated 100Ω termination
• Supports PCIe Gen 1–6 Common Clock and Independent Reference architectures
• Spread spectrum input tolerant
• Configurable via SMBus or hardware pins

Applications

• PCIe Gen 1–6 system clock distribution
• Server and storage backplane clocking
• High-speed data communication interfaces

Procurement Notes

Verify the specific suffix 'BKILF' against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly from the datasheet as distributor listings may vary in detail accuracy.

Selection Notes

Select this component for designs requiring low-power LVPECL/LVDS replacement with LP-HCSL signaling. Ensure the design accommodates the 3.3V supply voltage and utilizes the integrated 100Ω termination for impedance matching on 100Ω differential traces.

Part Context

This part belongs to the 9DBL04xx family of PCIe clock buffers. While the 9DBL0452 provides four outputs, the 9DBL0242 variant specifically offers two outputs, providing a compact solution for applications requiring fewer clock lanes while maintaining PCIe Gen 6 jitter performance standards.

Replacement Considerations

Direct replacements include other members of the 9DBL04xx series such as the 9DBL0452, provided the additional outputs are acceptable. Verify that any substitute maintains LP-HCSL output signaling and 3.3V operation.
