9DB801BFLF

Overview

The Renesas 9DB801BFLF is a zero-delay buffer integrated circuit designed for PCI Express (PCIe) applications. It features a single input to eight output configuration with a maximum frequency of 400 MHz. The device operates on a supply voltage range of 3.135 V to 3.465 V and supports HCSL inputs with HCSL/LVDS outputs. Packaged in a 48-SSOP, it functions within an operating temperature range of 0°C to 70°C. This component is classified as a clock buffer intended for specific timing requirements in PCIe Gen1 systems.

Feature Summary

• Zero-delay buffering architecture for PCI Express Gen1
• 1:8 input-to-output ratio with differential support
• Maximum operating frequency of 400 MHz
• HCSL input interface compatible with HCSL or LVDS outputs

Applications

• PCI Express Gen1 clock distribution
• System board timing synchronization
• Peripheral interface clock buffering

Procurement Notes

This component has reached End-of-Life (EOL) status, with discontinuance notices recorded in April 2018. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Sourcing should prioritize verified suppliers due to the discontinued manufacturing status.

Selection Notes

Select this part only if the design specifically requires a PCIe Gen1 zero-delay buffer with an 8-output fan-out. Ensure the system voltage matches the 3.135 V to 3.465 V range and that the 48-SSOP package fits the PCB layout constraints. Consider newer generations if PCIe Gen2/Gen3 support or lower power consumption is required.

Part Context

The 9DB801BFLF belongs to the 9DB801 series of clock buffers manufactured by Renesas Electronics. It was originally developed under the IDT brand before the acquisition by Renesas. The 'LF' suffix indicates lead-free compliance, and 'B' typically denotes specific packaging or testing variations within the SSOP-48 form factor.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Renesas technical support for recommended alternatives or evaluate the 9DB803 series for PCIe Gen2 compatibility.
