ZL40218LDG1

Overview

The ZL40218LDG1 is a clock fanout buffer manufactured by Microchip Technology, designed for high-speed signal distribution. It features a single input to eight output configuration with differential LVDS outputs. The device supports multiple input formats including CML, HCSL, LVCMOS, LVDS, and LVPECL. It operates within a supply voltage range of 2.375 V to 3.465 V and supports maximum input frequencies up to 750 MHz. The component is housed in a 32-VFQFN package with exposed pad and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports flexible input signal compatibility across CML, HCSL, LVCMOS, LVDS, and LVPECL standards
• Provides eight differential LVDS outputs for robust clock distribution
• Operates within a wide supply voltage range from 2.375 V to 3.465 V

Applications

• High-speed digital system clock distribution
• Telecommunications infrastructure timing networks
• Data center server backplane synchronization

Procurement Notes

Verify the specific suffix 'LDG1' against the official Microchip datasheet to confirm package type and temperature grade. Ensure design compliance with RoHS directives as indicated in manufacturer documentation. Cross-reference the Mouser part number 494-ZL40218LDG1 or DigiKey identifier ZL40218LDG1-ND for accurate sourcing channels. Confirm availability status directly with authorized distributors as inventory levels fluctuate.

Selection Notes

Select this component when an eight-channel LVDS fanout buffer is required for systems supporting mixed input logic levels. The device is suitable for designs needing operation at frequencies up to 750 MHz. Consider the 32-QFN package constraints for PCB layout. Verify that the 2.375 V minimum supply voltage aligns with the target system power rails before finalizing the bill of materials.

Part Context

This part belongs to the ZL402xx series of clock buffers from Microchip Technology. It shares architectural similarities with variants like the ZL40219LDG1 and ZL40208LDG1 but differs in input/output ratios and termination configurations. The series is categorized under Clock & Timer ICs, specifically designed for low skew and jitter performance in complex electronic systems requiring precise timing signals.

Replacement Considerations

The ZL40218LDF1 is documented as a parameter-equivalent alternative. Designers should verify pinout compatibility and electrical specifications against the official datasheets before substitution.
