ZL40217LDF1

Overview

The ZL40217LDF1 is a clock fanout buffer manufactured by Microchip Technology, designed for high-speed signal distribution. It features a 1:6 output configuration with an internal termination mechanism to ensure signal integrity. The device supports a maximum input frequency of 750 MHz and exhibits a maximum propagation delay of 2 ns. It operates within a supply voltage range of 2.375 V to 3.465 V and is housed in a 32-pin VFQFN package with an exposed pad. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Provides one-to-six fanout buffering for LVDS clock signals
• Integrates internal termination resistors for improved signal quality
• Supports high-frequency operation up to 750 MHz
• Features low propagation delay for precise timing control

Applications

• High-speed data acquisition systems
• Telecommunications infrastructure equipment
• Test and measurement instruments
• Industrial automation controllers

Procurement Notes

Verify the specific suffix 'F1' against the manufacturer's official documentation to confirm the tape-and-reel packaging format. Ensure that the selected variant matches the required operating temperature range and voltage specifications for the target application environment. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a single LVDS source must drive six distinct loads with minimal skew. Consider the 32-VFQFN package constraints regarding thermal dissipation and PCB layout space. Evaluate the 2.375 V minimum supply requirement against available power rails. Confirm that the 750 MHz maximum frequency aligns with the system's clock generation architecture.

Part Context

This part belongs to Microchip's ZL402xx series of clock buffers and drivers. These devices are engineered for jitter attenuation and signal distribution in complex digital systems. The ZL40217 specifically targets LVDS applications, offering a compact solution for distributing reference clocks across multiple subsystems without significant signal degradation or timing errors.

Replacement Considerations

The ZL40217LDG1 is a documented substitute part number for this component, differing primarily in packaging type.
