9DB801BGLFT

Overview

The Renesas Electronics Corporation 9DB801BGLFT is a clock buffer IC designed for PCI Express (PCIe) applications. It features an 1:8 input-to-output ratio, converting a single HCSL differential input into eight HCSL/LVDS differential outputs. The device supports a maximum frequency of 400 MHz and operates within a supply voltage range of 3.135 V to 3.465 V. Manufactured in a 48-SSOP package with a width of 7.50 mm, it functions within a commercial temperature range of 0°C to 70°C. This component serves as a zero-delay buffer for PCIe clock distribution.

Feature Summary

• Provides 8 differential outputs from a single differential input for PCIe clock distribution
• Supports frequencies up to 400 MHz in bypass mode
• Operates on a 3.135 V to 3.465 V power supply
• Available in a 48-pin SSOP surface-mount package

Applications

• PCI Express (PCIe) clock buffering
• Zero-delay buffer configurations
• Fanout clock distribution

Procurement Notes

The 9DB801BGLFT is listed as obsolete or end-of-life by the manufacturer. Verification of current stock availability through authorized distributors is required before procurement planning. Alternative components should be identified if long-term supply continuity is necessary for production.

Selection Notes

Select this component when an 8-channel differential clock buffer is needed for PCIe Gen1 systems operating at frequencies up to 400 MHz. Ensure the design accommodates the 48-SSOP footprint and the specific 3.3 V nominal supply voltage requirements. Verify that the HCSL/LVDS output signaling meets the receiver specifications of the target application.
