ZL40219LDF1

Overview

The ZL40219LDF1 is a clock buffer and fanout buffer manufactured by Microchip Technology. It features one input channel and eight LVDS output channels, supporting a maximum operating frequency of 750 MHz. The device operates within a supply voltage range of 2.375 V to 3.465 V and includes internal termination resistors for the outputs. It is housed in a 32-VFQFN package with an exposed pad, designed for surface-mount installation. The component supports multiple differential input types including CML, HCSL, LVCMOS, LVDS, and LVPECL.

Feature Summary

• Eight LVDS output channels with integrated termination
• Maximum operating frequency of 750 MHz
• Supports CML, HCSL, LVCMOS, LVDS, and LVPECL inputs
• Operates on a single 2.375 V to 3.465 V supply

Applications

• High-speed data acquisition systems
• Telecommunications infrastructure
• Test and measurement equipment

Procurement Notes

Verify the suffix 'LDF1' indicates tape-and-reel packaging distinct from the 'LDG1' tray variant. Confirm RoHS compliance status via the manufacturer's official documentation before procurement. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification.

Selection Notes

Select this model when eight LVDS outputs with internal termination are required. Compare against ZL40218 for similar functionality but different packaging options. Verify that the 750 MHz frequency limit meets system requirements. Check compatibility with existing input signal standards such as LVDS or CML.

Part Context

This component belongs to the ZL402x series of clock buffers from Microchip Technology. The series offers various fan-out combinations with low skew and jitter performance. These devices are designed to distribute clock signals across complex digital systems while maintaining signal integrity.

Replacement Considerations

ZL40218LDG1 is a parameter-equivalent alternative offering identical electrical specifications. Consider ZL40218LDF1 for direct pin-to-pin replacement with matching tape-and-reel packaging. Verify package dimensions and thermal characteristics before substitution.
