9DBV0841AKILFT

Overview

The 9DBV0841AKILFT is a clock buffer manufactured by Renesas Electronics Corporation, designed for PCI Express (PCIe) applications. It features eight differential outputs and accepts a single differential input. The device operates with an HCSL input signal and provides LP-HCSL output signaling. It supports frequencies up to 200 MHz and functions within a supply voltage range of 3.135 V to 3.465 V. The component is housed in a 48-VFQFPN package with dimensions of 6.0 x 6.0 mm and a pitch of 0.4 mm. It includes integrated terminations for direct connection to 100Ω transmission lines.

Feature Summary

• Eight differential outputs with integrated 100Ω terminations
• Supports PCIe Gen1-Gen4 clock distribution
• Operates at 3.3V nominal supply voltage
• HCSL input to LP-HCSL output conversion

Applications

• PCIe Riser Cards
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control and Embedded Systems

Part Context

This component belongs to the 9DBV family of PCIe clock buffers from Renesas. The family includes variants with different output counts, such as the 9DBV05x1, 9DBV07x1, and 9DBV09x1 series. These devices are engineered to provide low-power, low-voltage clock distribution solutions compliant with PCIe specifications.

Replacement Considerations

Public documentation indicates that the Renesas timing product portfolio has been acquired by SiTime. New designs should consult SiTime.com for equivalent components or support. Existing procurement channels remain active through Renesas until the end of 2026.
