9DBU0841AKLFT

Overview

The 9DBU0841AKLFT is a clock buffer manufactured by Renesas Electronics Corporation, designed for PCI Express applications. It features one differential input and eight differential outputs with a maximum frequency of 200MHz. The device operates on a single 3.3V supply voltage and utilizes HCSL signaling standards for both input and output interfaces. It is housed in a 48-VFQFPN package measuring 6x6 mm with exposed pads. The component supports an operating temperature range from -40°C to 85°C and includes integrated PLL functionality.

Feature Summary

• Eight differential outputs supporting up to 200MHz operation
• Integrated Phase-Locked Loop (PLL) for clock generation
• HCSL input/output signaling compatible with PCIe standards
• Single 3.3V power supply requirement

Applications

• PCI Express clock distribution
• High-speed digital system timing
• Server and storage infrastructure

Procurement Notes

Verify the specific suffix 'AKLFT' against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notices or product change notifications that may affect availability or assembly sites.

Selection Notes

Select this component when eight differential HCSL outputs are required at frequencies up to 200MHz within a compact 48-pin VFQFPN footprint. Ensure the design environment supports the specified 3.3V supply voltage and the -40°C to 85°C industrial temperature range. Verify compatibility with the source clock signal characteristics.

Part Context

This part belongs to the 9DBU series of zero-delay fanout buffers from Renesas. These devices are engineered to provide low-jitter clock distribution for high-speed serial interfaces like PCIe. The 9DBU0841 variant specifically provides an 1:8 split ratio, making it suitable for driving multiple endpoints from a single reference clock source.
