9DBV0641AKILFT

Overview

The 9DBV0641AKILFT is a six-output, 1.8V PCIe clock generator supporting Gen1 through Gen3 standards. It features zero-delay feedback architecture to minimize jitter and includes integrated terminations for direct connection to 100Ω transmission lines. The device operates within a frequency range of 1MHz to 200MHz and accepts spread spectrum inputs for EMI reduction. It utilizes an HCSL-compatible differential input and provides LP-HCSL differential outputs. The component is housed in a space-saving 5mm x 5mm 32-pin VFQFPN package with exposed pads.

Feature Summary

• Zero-delay feedback architecture for low-jitter performance
• Integrated 100Ω terminations for direct PCB trace connection
• Supports PCIe Gen1, Gen2, and Gen3 signaling standards
• Spread spectrum capability for EMI mitigation

Applications

• PCI Express riser cards
• NVMe storage controllers
• Networking accelerators
• Industrial control systems

Procurement Notes

Verify RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly. Confirm the specific suffix 'AKILFT' matches the required tape-and-reel packaging quantity and lead finish specifications. Ensure design compatibility with 1.8V core voltage requirements and SMBus interface constraints if programmable features are utilized.

Selection Notes

Select this model when a fixed-frequency, zero-delay buffer is required for 1.8V PCIe applications up to Gen3 speeds. Compare against the 9DBV0541 or 9DBV0741 variants if different output counts are needed. Verify that the HCSL input signal source is compatible with the device's input threshold requirements before finalizing the design.

Part Context

This component belongs to the Renesas 9DBV06x1 family of PCIe clock buffers. The manufacturer has been acquired by SiTime, which will continue to support datasheets and ordering until the end of 2026. Designers should be aware of this transition when planning long-term production cycles or sourcing replacement components after the transition period.
