9DBV0941AKILFT

Overview

The 9DBV0941AKILFT is a 9-output, 1.8V PCIe fanout clock buffer from Renesas Electronics Corporation. It operates within a frequency range of 1MHz to 200MHz 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 clock management and supports selectable SMBus addresses. 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 connection
• HCSL input to LP-HCSL output signaling conversion
• SMBus-selectable features including three configurable addresses
• Spread spectrum compatible for EMI reduction

Applications

• PCI Express (PCIe) clock distribution networks
• High-speed data acquisition systems requiring low jitter
• Server and storage infrastructure timing architectures

Procurement Notes

Verify the current lifecycle status as sources indicate this part may be obsolete or subject to transition. Confirm package availability and moisture sensitivity level (MSL 3) requirements during handling. Ensure compatibility with existing SMBus configurations if multiple devices share a segment.

Selection Notes

Select this component when nine differential clock outputs are required at 1.8V. Verify that the system requires HCSL input compatibility. Consider the 48-VFQFPN package size constraints against available board space. Ensure the operating temperature range meets the specific application environment requirements.

Part Context

This device belongs to the 9DBV05x1-9DBV07x1-9DBV09x1 family of PCIe clock buffers. It shares architectural similarities with the 9DBV0541 and 9DBV0741 but provides a higher output count. The product line is associated with Renesas' full-featured PCIe portfolio, which has been acquired by SiTime.
