9DBV0531AKLFT

Specialized Overview

The 9DBV0531AKLFT is a five-output, 1.8 V PCIe Gen1-2-3 fanout buffer manufactured by Renesas Electronics. It operates within a frequency range of 1 MHz to 200 MHz and accepts HCSL-compatible differential inputs. The device features integrated terminations for direct connection to 100 Ω transmission lines, eliminating external resistors. It includes five output enable pins for clock management and three selectable SMBus addresses. The component is housed in a space-saving 5 mm x 5 mm 32-pin VFQFPN package.

Specialized Feature Summary

• Supports PCIe Gen1 through Gen3 standards with integrated 100 Ω termination resistors for direct transmission line connection.
• Features five independent output enable pins to facilitate dynamic clock management and power optimization.
• Includes an SMBus interface with selectable addresses, allowing configuration without requiring active software control.

Specialized Applications

• PCI Express system clock distribution
• High-performance server motherboards
• Storage area network infrastructure

Specialized Procurement Notes

Verify the specific suffix AKLFT against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 32-pin VFQFPN format. Confirm that the 1.8 V supply voltage aligns with the target system design requirements before finalizing procurement.

Specialized Selection Notes

Select this component when a low-power, multi-output fanout solution is required for PCIe Gen1-3 architectures. It is suitable for designs needing integrated termination to reduce bill-of-materials complexity. Consider alternative models if higher output counts or different voltage levels are necessary for the specific application.

Specialized Part Context

This part belongs to the 9DBV05x1 family of PCIe fanout buffers from Renesas Electronics. These devices are designed to replace discrete resistor networks and standard buffers, offering a compact footprint and reduced power consumption compared to traditional solutions.

Specialized Replacement Considerations

The 9DBV0541 serves as a verified replacement within the same family, offering identical functionality and pinout compatibility while maintaining the 1.8 V operation and five-output configuration.
