9DBU0831AKILF

Overview

The 9DBU0831AKILF is a clock buffer manufactured by Renesas Electronics, designed for high-performance timing applications. It features one input and eight outputs, supporting LP-HCSL output signaling with an HCSL input interface. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports maximum frequencies of 150 MHz for both input and output signals. It is housed in a 48-lead VFQFPN package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Eight-output configuration with LP-HCSL output signaling
• Supports maximum operating frequency of 150 MHz
• Operates on a single 3.3V supply (3.135 V to 3.465 V)
• Housed in a compact 48-VFQFPN surface-mount package

Applications

• PCI Express (PCIe) clock distribution
• Intel QPI clock buffering
• General-purpose high-speed digital system timing

Procurement Notes

Verify the specific suffix 'KILF' against official Renesas documentation to confirm pinout, lead finish, and moisture sensitivity level details. Ensure compatibility with standard RoHS3 compliance requirements for the target assembly process. Confirm availability status as distributor listings may vary.

Selection Notes

Select this component when an eight-channel low-power HCSL buffer is required for PCIe or QPI architectures. Verify that the 150 MHz frequency limit meets the system's clock speed requirements. Ensure the PCB layout accommodates the 48-VFQFPN package dimensions and thermal dissipation needs for continuous operation at 0°C to +70°C.

Part Context

This part belongs to the 9DBU series of clock buffers from Renesas, optimized for low power consumption in high-speed serial link applications. It serves as a fan-out buffer to drive multiple loads from a single source signal while maintaining signal integrity across PCIe generations.

Replacement Considerations

Consult Renesas datasheets for direct cross-references within the 9DBU family. Verify pin-to-pin compatibility before substituting with other eight-output HCSL buffers from different manufacturers.
