9DB803DFLF

Overview

The 9DB803DFLF is an 8-output differential clock buffer designed for PCI Express Gen2 applications. Manufactured by Renesas Electronics, it operates within a supply voltage range of 3.135 V to 3.465 V and supports maximum input frequencies up to 400 MHz. The device features zero propagation delay and is housed in a 48-pin SSOP package. It functions as a distribution IC with HCSL output signaling, suitable for generating multiple PCIe clocks from a single source.

Feature Summary

• Provides 8 differential outputs for PCI Express Gen2 clock distribution
• Supports zero delay buffer mode and fanout mode
• Operates at input frequencies up to 400 MHz in bypass mode
• Housed in a 48-lead SSOP package

Applications

• PCI Express Gen2 system clock generation
• Server and storage backplane clock distribution
• High-performance computing platforms requiring low jitter

Procurement Notes

Verify the specific suffix 'DFLF' against official Renesas documentation to confirm the commercial temperature grade (0°C to +70°C) and tube packaging format. Ensure compatibility with existing PCB footprints for the 48-SSOP package before procurement.

Selection Notes

Select this component when eight synchronized differential clocks are required for PCIe Gen2 interfaces. Compare against the -DGLF variant if industrial temperature operation (-40°C to +85°C) is necessary. Verify that the 400 MHz frequency requirement aligns with the bypass mode specifications.

Part Context

This part belongs to the 9DB803 family of differential buffers. It serves as a successor or alternative to earlier IDT-branded versions, maintaining functional compatibility while adhering to current Renesas product lines. It is distinct from the 9DB803DFILF, which offers extended temperature ratings.

Replacement Considerations

The 9DB803DGLF is a verified replacement offering identical functionality with an extended industrial temperature range (-40°C to +85°C). Verify pinout compatibility during substitution.
