9DBV0741AKLF

Overview

The Renesas 9DBV0741AKLF is a seven-output, 1.8V PCIe fanout clock buffer designed for high-speed digital systems. It features integrated 100Ω terminations for direct connection to transmission lines, eliminating external resistors. The device supports HCSL differential inputs and LP-HCSL outputs, operating within a frequency range of 1 MHz to 200 MHz. It includes seven output enable pins for power management and three selectable SMBus addresses for configuration flexibility. The component is housed in a space-saving 5x5 mm 32-pin VFQFPN package with exposed pads.

Feature Summary

• Seven differential outputs with integrated 100Ω terminations for direct PCB trace connection
• HCSL-compatible differential input supporting common clock sources and spread spectrum signals
• SMBus-selectable features including programmable slew rate and output amplitude tuning
• Low power consumption with typical operation at 45mW and OE# pins for individual output control

Applications

• PCI Express Gen 1 through Gen 5 compliant system designs
• High-performance computing platforms requiring low-jitter clock distribution
• Telecommunications infrastructure equipment
• Industrial automation controllers

Procurement Notes

Verify the specific suffix 'AKLF' against the manufacturer's current datasheet to confirm pinout compatibility and moisture sensitivity level (MSL). Check for product change notifications (PCNs) regarding packaging or material composition updates. Ensure the source document explicitly lists this part number as active or long-term supply, as availability may vary by region.

Selection Notes

Select this component when a single HCSL input must drive seven LP-HCSL loads with minimal board space. The integrated termination resistors reduce BOM count compared to standard HCSL buffers. Verify that the required operating frequency falls within the 1 MHz to 200 MHz range and that the 1.8V supply voltage aligns with the target system architecture.

Part Context

This device belongs to the Renesas 9DBV05x1-07x1-09x1 family of PCIe fanout clock buffers. Variants in this series differ primarily by the number of outputs (5, 7, or 9) while sharing similar electrical characteristics and package options. The 9DBV0741AKLF specifically provides a middle-ground solution between the 5-output and 9-output models.

Replacement Considerations

Direct substitutes include other members of the same family, such as the 9DBV0541AKLF (5-output) or 9DBV0941AKLF (9-output), provided the output count difference is acceptable. Cross-reference tools should be used to identify parametrically similar parts from other manufacturers if the exact model is unavailable.
