9DBU0531AKILF

Overview

The Renesas 9DBU0531AKILF is a PCIe clock buffer designed for high-speed data transmission applications. It operates with a single 1.5V supply voltage and supports PCIe Gen1, Gen2, and Gen3 standards. The device features one input and five outputs, providing fanout buffering capabilities. It utilizes Low Power HCSL (LP-HCSL) output signaling to minimize power consumption while maintaining signal integrity. The component is housed in a 32-VFQFPN package with exposed pad, suitable for surface mount assembly. It is rated for operation over an extended industrial temperature range of -40°C to +85°C.

Feature Summary

• Five-output LP-HCSL fanout buffer supporting PCIe Gen1/Gen2/Gen3
• Single 1.5V supply voltage operation
• 1:5 input-to-output ratio
• 32-VFQFPN (5x5 mm) package with exposed thermal pad

Applications

• PCI Express root complex clock distribution
• Switch fabric clock buffering
• High-performance server and storage systems

Procurement Notes

Verify the specific suffix 'AKILF' against the official Renesas datasheet to confirm package type, moisture sensitivity level, and RoHS compliance status. Ensure that the ordering information matches the exact electrical specifications required for the target PCIe generation. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a low-power, multi-output buffer is required for PCIe interfaces operating at Gen1 through Gen3 speeds. The 1.5V supply requirement aligns with standard PCIe I/O voltage levels. Consider the 32-VFQFPN package dimensions during PCB layout planning to ensure adequate thermal dissipation via the exposed pad. Verify that the input source meets the LVCMOS or HCSL requirements specified in the datasheet.

Part Context

This part belongs to the Renesas 9DBU series of PCIe clock buffers. It is distinct from the 9DBV series, which may offer different output configurations or voltage options. The 9DBU series is specifically optimized for PCIe compliance, ensuring jitter performance meets industry standards for reliable data transfer in modern computing architectures.

Replacement Considerations

Consult the Renesas product selection guide for direct pin-compatible replacements within the 9DBU family. Alternative parts may include variants with different output counts or voltage tolerances. Verify that any substitute component maintains compatibility with the specific PCIe generation and LP-HCSL signaling requirements of the design.
