9DBV0831AKILFT

Overview

The Renesas 9DBV0831AKILFT is an 8-output very low power clock buffer designed for PCIe Gen1–5 applications. It operates with a single 1.8V supply and features LP-HCSL differential outputs. The device supports input frequencies from 30MHz to 137.5MHz and accepts spread spectrum inputs for EMI reduction. It includes eight output enables for individual clock management and three selectable SMBus addresses. Packaged in a space-saving 48-pin VFQFPN (6.0 x 6.0 mm) with a 0.4mm pitch, it consumes approximately 62mW typical power.

Feature Summary

• Eight differential LP-HCSL outputs with hardware control via OE# pins
• Supports PCIe Gen1 through Gen5 and Ethernet applications up to 137.5MHz
• Low power consumption of 62mW typical at 1.8V supply
• Spread spectrum input compatibility for EMI mitigation

Applications

• PCI Express (PCIe) Gen1/Gen2/Gen3/Gen4/Gen5 systems
• Ethernet network infrastructure equipment
• High-speed server and storage backplanes

Procurement Notes

Verify the suffix 'AKILFT' corresponds to the tape and reel packaging format as specified by Renesas. Confirm the operating temperature range is industrial (-40°C to +85°C). Ensure the 48-pin VFQFPN footprint matches the PCB layout design guidelines provided in the official datasheet.

Selection Notes

Select this component when an 8-channel fanout buffer is required for 1.8V logic families. It is suitable for designs needing zero-delay buffering or simple fanout with spread spectrum support. Compare against the 9DBV0431 if fewer outputs are sufficient, or the 9ZXL series for higher voltage requirements.

Part Context

This part belongs to the Renesas 9DBV family of ultra-low-power PCIe clock buffers. It serves as a direct replacement for legacy IDT clock distribution devices in modern high-speed serial link architectures, offering improved power efficiency and signal integrity for next-generation interface standards.
