9DB801BFLFT

Overview

The 9DB801BFLFT is a PLL-based clock buffer manufactured by Renesas Electronics, designed for PCI Express Gen 1 applications. It features one differential input and eight true differential outputs, housed in a 48-pin TSSOP package. The device operates on a single 3.3V supply (3.135V to 3.465V) with a maximum frequency of 101MHz. It provides zero-delay buffering capabilities to maintain signal integrity across PCIe lanes.

Feature Summary

• Eight differential outputs supporting PCI Express Gen 1 standards
• Zero-delay buffering architecture for minimal skew
• Integrated PLL for jitter attenuation
• Single 3.3V power supply operation

Applications

• PCI Express Gen 1 system clock distribution
• High-speed digital interface buffering
• Server and workstation motherboard clocking

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability is restricted to existing stock or surplus markets. Buyers must confirm the specific manufacturing lot date and physical condition prior to acquisition, as standard supply channels are inactive.

Selection Notes

Select this part only for legacy designs requiring Gen 1 PCIe buffering. Verify that the 101MHz maximum frequency meets system requirements. Ensure the 48-pin TSSOP footprint matches the PCB layout. New designs should consider modern alternatives supporting higher PCIe generations.

Part Context

Part of the 9DB series from Integrated Device Technology (IDT), now part of Renesas. This specific model serves as a buffer for distributing reference clocks to multiple PCIe endpoints in a system.

Replacement Considerations

As a discontinued item, direct replacements are not guaranteed. Evaluate newer Renesas clock buffers with compatible pinouts and electrical specifications for design updates.
