9DBV0941AKILF

Overview

The 9DBV0941AKILF is a 9-output, 1.8V PCIe fanout clock buffer manufactured by Renesas Electronics Corporation. It operates within a frequency range of 1 MHz to 200 MHz and accepts HCSL differential inputs while providing LP-HCSL differential outputs. The device features integrated 100Ω terminations for direct connection to transmission lines, eliminating external resistors. It includes nine output enable pins for power management and supports spread spectrum modulation for EMI reduction. The component is housed in a 48-lead VFQFPN package with dimensions of 6.0 x 6.0 mm.

Feature Summary

• Nine differential outputs with integrated 100Ω terminations for direct PCB trace connection
• Supports PCIe Gen 1 through Gen 5 standards with operating frequencies up to 200 MHz
• Features nine independent output enable pins for dynamic clock management
• Includes three selectable SMBus addresses for configuration and control

Applications

• PCI Express (PCIe) clock distribution systems
• High-performance computing platforms requiring low-power clock buffering
• Server and storage infrastructure designs

Part Context

This component belongs to the 9DBV05x1-9DBV07x1-9DBV09x1 family of PCIe fanout clock buffers. While the manufacturer has been acquired by SiTime, official datasheets and documentation remain available on the Renesas website until the end of 2026. The part is designated as obsolete or end-of-life status in some distributor catalogs.

Replacement Considerations

The 9DBV0941BKLFT is listed as a manufacturer-recommended replacement. Designers should verify pin compatibility and electrical specifications against the specific application requirements before substitution.
