9DBU0641AKILFT

Overview

The Renesas 9DBU0641AKILFT is a PCIe zero-delay fanout buffer designed for high-speed clock distribution. It accepts one differential HCSL input and provides six differential LP-HCSL outputs, supporting frequencies up to 167 MHz. The device operates on a single 1.5 V supply (1.425 V to 1.575 V) within an industrial temperature range of -40°C to +85°C. Packaged in a compact 40-VFQFPN (5x5 mm) format, it integrates jitter attenuation capabilities suitable for PCI Express Gen1 through Gen3 applications.

Feature Summary

• Six differential LP-HCSL outputs with zero-delay feedback architecture
• Supports PCIe Gen1, Gen2, and Gen3 clock standards
• Integrated jitter attenuation for signal integrity optimization
• Operates at 1.5 V with low power consumption

Applications

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

Procurement Notes

Verify the specific suffix 'AKILFT' against the official datasheet to confirm package type, tape-and-reel quantity, and RoHS compliance status. Ensure the ordering code matches the required operating temperature range and moisture sensitivity level before procurement.

Selection Notes

Select this component when a single HCSL source must drive multiple PCIe endpoints with minimal skew. Compare output count and voltage levels against alternatives like the 9DBU0631 or 9DBL series to ensure compatibility with the target system's power budget and form factor constraints.

Part Context

This part belongs to the 9DBU06xx family of PCIe clock buffers. It shares architectural similarities with other members but is distinct in its six-output configuration and 1.5 V operation, differentiating it from 3.3V variants or different output counts within the same product line.

Replacement Considerations

Direct substitutes include other 6-output PCIe buffers from Renesas such as the 9DBU0631AKILFT, provided the voltage and frequency requirements align. Verify pin-to-pin compatibility and electrical specifications before substitution.
