9DB403DFILF

Overview

The Renesas Electronics 9DB403DFILF is a PCI Express (PCIe) fanout buffer and zero-delay buffer integrated circuit. It features a single HCSL differential input driving four differential outputs in HCSL or LVDS formats. The device supports maximum frequencies of 400 MHz with a supply voltage range of 3.135 V to 3.465 V. Manufactured in a 28-SSOP package, it operates within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Four-output PCIe fanout buffer with zero-delay buffering capability
• Differential HCSL input supporting up to 400 MHz frequency
• Flexible output configurations available in HCSL or LVDS formats
• Single power supply operation between 3.135 V and 3.465 V

Applications

• PCI Express (PCIe) clock distribution networks
• System board timing solutions for server platforms
• High-speed digital interface synchronization

Procurement Notes

Verify the specific suffix 'DFILF' against official Renesas documentation to confirm the tube packaging format and commercial temperature grade. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into surface-mount assembly processes.

Selection Notes

Select this component when a single differential source must drive four distinct loads with minimal skew. Ensure the target application requires HCSL or LVDS outputs and operates within the 0°C to 70°C temperature range. Verify that the 28-SSOP footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the 9DB403 family of PCIe clock buffers. Variants such as 9DB403DFLF differ primarily in packaging type, while 9DB403DGLFT utilizes TSSOP-28 packaging. All variants share the core 1:4 buffering functionality and electrical specifications defined by the base model.

Replacement Considerations

Direct substitutes include other members of the 9DB403 family, such as 9DB403DFLF or 9DB403DGLFT, provided the package style matches the design requirements.
