9DBU0741AKLF

Overview

The 9DBU0741AKLF is a 1.5V PCIe fanout clock buffer designed for low-power applications. It features seven outputs with integrated terminations, eliminating the need for external resistors on 100-ohm transmission lines. The device operates at frequencies from 1 MHz to 167 MHz and consumes approximately 36 mW of power. Each output includes an independent enable pin for clock management. It supports spread spectrum inputs and utilizes a 3.3V-tolerant SMBus interface for configuration.

Feature Summary

• Seven differential outputs with integrated 100-ohm terminations
• Ultra-low power consumption of 36 mW typical
• Independent output enable pins for each channel
• Spread spectrum tolerant input architecture

Applications

• PCIe Gen 1/2/3 reference clock distribution
• Server and storage system clocking
• High-performance computing platforms

Part Context

This component belongs to Renesas' (formerly IDT) 1.5V Ultra-Low-Power PCIe family. It is housed in a space-saving 5x5 mm 40-pin VFQFPN package. The device allows for selectable SMBus addresses, facilitating multiple devices on a single bus segment without requiring the interface for default operation.

Replacement Considerations

Verify pin compatibility and termination requirements when substituting. Ensure the replacement supports the specific PCIe generation and frequency range required by the design.
