9DBV0641AKLF

Overview

The Renesas 9DBV0641AKLF is a six-output clock generator designed for PCIe Gen1, Gen2, and Gen3 applications. Operating at 1.8V, it features zero-delay feedback architecture to minimize jitter. The device integrates spread spectrum capability to reduce EMI. It supports differential input and output signaling with LP-HCSL outputs. The component is housed in a compact VFQFPN package suitable for high-density designs.

Feature Summary

• Six differential outputs supporting PCIe Gen1/2/3 standards
• Zero-delay feedback loop for low jitter performance
• Integrated spread spectrum frequency modulation
• 1.8V supply voltage operation

Applications

• PCIe Riser Cards
• NVMe Storage Systems
• Networking Accelerators

Procurement Notes

Verify the RoHS compliance status and moisture sensitivity level (MSL) before procurement. Confirm the specific package variant matches the design requirements. Check for any product change notifications that may affect pinout or electrical characteristics. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a low-jitter, multi-output clock solution is required for PCIe interfaces. The zero-delay feature makes it suitable for systems demanding precise clock alignment. Consider the 1.8V operating voltage and LP-HCSL output levels for compatibility with downstream receivers. Evaluate the thermal performance within the VFQFPN package for the target application environment.

Part Context
