ZL40211LDG1

Overview

The ZL40211LDG1 is a clock fanout buffer manufactured by Microchip Technology, housed in a 32-VFQFN exposed pad package. It operates with a supply voltage range of 2.375 V to 3.465 V and supports a maximum frequency of 750 MHz. The device functions as a 2:8 multiplexer, accepting inputs from CML, HCSL, LVCMOS, LVDS, or LVPECL sources and providing eight LVPECL outputs. It is designed for surface mount installation within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports multiple input standards including CML, HCSL, LVCMOS, LVDS, and LVPECL
• Provides eight LVPECL output channels for signal distribution
• Integrates external termination capabilities for output impedance matching

Applications

• High-speed data acquisition systems requiring precise clock distribution
• Telecommunications infrastructure equipment
• Test and measurement instruments

Procurement Notes

Verify the specific suffix 'LDG1' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the required external termination components are included in the bill of materials, as the device relies on them for proper LVPECL operation. Confirm RoHS compliance status directly with the supplier documentation prior to finalizing procurement orders.

Selection Notes

Select this component when a system requires converting various differential or single-ended clock signals into eight matched LVPECL outputs. The 2:8 multiplexer architecture allows flexibility in source selection. Consider the 32-QFN package constraints for PCB layout and thermal management. Verify that the input signal levels align with the supported standards before implementation.
