9DBV0631BKLF

Overview

The 9DBV0631BKLF is a six-output, 1.8 V PCIe zero-delay clock buffer manufactured by Renesas Electronics Corporation. It belongs to the 9DBV05x1-9DBV07x1 family and supports PCIe Gen1 through Gen3 standards. The device features integrated terminations for direct connection to 100 Ω transmission lines and includes six output enable pins for flexible clock management. It offers three selectable SMBus addresses for configuration control. The component is housed in a 48-lead VFQFPN package with dimensions of 6.0 x 6.0 x 0.9 mm and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Six differential outputs supporting 1.8 V PCIe Gen1-2-3 applications
• Zero-delay architecture with integrated 100 Ω terminations
• Three selectable SMBus addresses for system configuration
• Six independent output enable pins for power management

Applications

• PCI Express (Gen1/Gen2/Gen3) clock distribution networks
• High-speed data acquisition systems requiring low-jitter timing
• Server and storage infrastructure clocking solutions

Procurement Notes

The 9DBV0631BKLF is classified as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors directly, as stock levels are not guaranteed. Designers should confirm lead times and potential obsolescence risks before finalizing procurement plans for this specific part number.

Selection Notes

Select the 9DBV0631BKLF when a six-channel 1.8 V PCIe clock buffer with zero-delay feedback is required. Ensure the design utilizes the 48-lead VFQFPN footprint (6.0 x 6.0 mm). Verify that the system voltage matches the 1.8 V specification and that SMBus compatibility aligns with the controller's address settings.

Part Context

This component is part of the broader 9DBV series from Renesas, which includes variants with different output counts such as the 9DBV05x1, 9DBV07x1, and 9DBV09x1 families. These devices share similar architectural features tailored for PCIe clock generation and distribution, differing primarily in the number of outputs and specific package configurations.

Replacement Considerations

Direct replacements may include other members of the 9DBV family, such as the 9DBV0531 or 9DBV0731, depending on whether fewer or additional outputs are acceptable. Cross-referencing pinouts and electrical specifications with the official datasheet is essential to ensure functional compatibility.
