9DBV0831AKILF

Overview

The 9DBV0831AKILF is an eight-output, very low-power clock buffer designed for PCIe Gen1–5 applications operating up to 100MHz. It supports 50MHz and 125MHz Ethernet frequencies via software selection. The device features LP-HCSL differential outputs and accepts HCSL differential inputs with spread spectrum capability. It operates on a single 1.8V supply, consuming approximately 62mW typical power. The component includes eight output enables for clock management and three selectable SMBus addresses, housed in a 48-lead VFQFPN package.

Feature Summary

• Eight differential LP-HCSL outputs supporting PCIe Gen1–5 (up to 100MHz) and Ethernet (50/125MHz)
• Single 1.8V supply voltage with typical power consumption of 62mW
• HCSL differential input accepting spread spectrum signals
• Eight independent output enables and three selectable SMBus addresses

Applications

• PCI Express Gen1 through Gen5 system clock distribution
• 100MHz Ethernet network infrastructure
• 50MHz or 125MHz Ethernet applications via software configuration

Procurement Notes

Verify the specific suffix 'AKILF' against the manufacturer datasheet to confirm package type, temperature range, and tape-and-reel packaging details. Ensure compatibility with 1.8V logic levels and SMBus addressing requirements for the target design.

Selection Notes

Select this component for designs requiring low-power clock buffering for high-speed PCIe or standard Ethernet interfaces. Confirm that the 1.8V supply rail matches the system voltage and that the 48-lead VFQFPN package fits the PCB layout constraints.

Part Context

This part belongs to Renesas' family of ultra-low-power PCIe clock generators and buffers. It serves as a fanout buffer solution for distributing reference clocks to multiple endpoints in server and networking equipment.

Replacement Considerations

Check for direct pin-to-pin replacements within the same Renesas 9DBV series or cross-reference with other vendors offering 8-output LP-HCSL buffers with similar 1.8V operation and SMBus control capabilities.
