ZL40218LDF1

Overview

The ZL40218LDF1 is a clock buffer and fanout distribution integrated circuit manufactured by Microchip Technology. It features a 1:8 input-to-output ratio, supporting a maximum operating frequency of 750 MHz. The device accepts multiple differential and single-ended input formats, including CML, HCSL, LVCMOS, LVDS, and LVPECL, while providing LVDS outputs. It operates within a supply voltage range of 2.375 V to 3.465 V and functions across an industrial temperature range of -40°C to +85°C. The component is housed in a 32-VFQFN package with an exposed pad, designed for surface-mount installation.

Feature Summary

Procurement Notes

Verify the specific suffix 'LDF1' against the official Microchip datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required input signal standards and output load requirements before integration into the design.

Selection Notes

Select this component when a single high-frequency clock source needs to be distributed to eight separate LVDS loads. Confirm that the system power supply falls within the 2.375 V to 3.465 V range and that the PCB layout accommodates the 32-VFQFN footprint with adequate thermal relief for the exposed pad.

Part Context

This part belongs to the ZL402xx series of SmartBuffer clock buffers from Microchip Technology. These devices are engineered for low-jitter performance and flexible configuration options, serving as critical timing elements in complex electronic architectures requiring precise clock distribution.

Replacement Considerations

The ZL40218LDG1 is listed as a parameter-equivalent alternative, differing primarily in packaging format. Verify pinout compatibility and thermal characteristics before substituting.
