9DBV0731AKILF

Overview

The 9DBV0731AKILF is a PCIe fanout clock buffer manufactured by Renesas Electronics Corporation. It features seven differential outputs and operates within a frequency range of 1 MHz to 200 MHz. The device utilizes LP-HCSL output signaling and accepts HCSL differential inputs. It supports spread spectrum input for EMI reduction and includes integrated 100-ohm terminations for direct connection to transmission lines. The component is housed in a space-saving 5 mm x 5 mm 32-pin VFQFPN package with exposed pads, suitable for surface-mount applications.

Feature Summary

• Seven differential outputs with LP-HCSL signaling
• Integrated 100-ohm termination resistors for direct line connection
• Spread spectrum compatible input for EMI reduction
• SMBus-selectable features including three selectable addresses

Applications

• PCI Express (PCIe) Gen 1 through Gen 5 clock distribution
• High-speed digital system clock buffering
• Server and storage backplane designs

Part Context

This component belongs to the 9DBV05x1-07x1-09x1 family of PCIe fanout clock buffers from Renesas. These devices are designed to provide low-power, high-performance clock distribution for multi-lane PCIe interfaces, offering configurable output enables and SMBus control for flexible system integration.

Replacement Considerations

The 9DMU0131AKILF is listed as an obsolete part with the 9DMV0131BKILF identified as a manufacturer-recommended replacement. For the 9DBV0731AKILF, verify specific pin-to-pin compatibility with other members of the 9DBV05x1-07x1-09x1 family if substituting based on output count requirements.
