ZL40293LDF1

Overview

The ZL40293LDF1 is a PCI Express (PCIe) fanout buffer and distribution IC manufactured by Microchip Technology. It operates at a maximum frequency of 250 MHz and provides one output channel. The device is housed in a 72-QFN package with dimensions of 10x10 mm. It supports a maximum duty cycle of 51% and functions within an operating temperature range from -40°C to +85°C.

Feature Summary

• Designed specifically for PCI Express signal distribution applications
• Provides single-channel fanout buffering capability
• Operates reliably across extended industrial temperature ranges

Applications

• PCI Express signal distribution networks
• High-speed digital interface buffering
• Server and storage system clock routing

Procurement Notes

Verify the specific suffix LDF1 against official Microchip documentation to confirm the reel packaging configuration and moisture sensitivity level. Ensure that the 72-QFN footprint matches the target PCB design constraints. Confirm RoHS compliance status through the manufacturer's current environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a dedicated PCIe fanout buffer is required for signal integrity maintenance. The 250 MHz speed rating suits standard PCIe generation requirements. Consider the 72-QFN package size for board space limitations. Verify input signal compatibility with the intended source driver specifications prior to integration into the circuit design.
