ZL40223LDG1

Overview

The ZL40223LDG1 is a clock fanout buffer manufactured by Microchip Technology, designed for high-speed signal distribution. It features a 2:8 output configuration, providing one input channel and eight output channels to distribute clock signals across multiple loads. The device operates within a supply voltage range of 2.375V to 3.465V and supports frequencies up to 750MHz. It is housed in a compact 32-QFN (5x5 mm) package, suitable for space-constrained applications requiring precise timing.

Feature Summary

• Provides 2:8 fanout buffering capability for distributing clock signals to multiple destinations
• Supports high-frequency operation up to 750MHz for demanding timing applications
• Operates on a single low-voltage power supply ranging from 2.375V to 3.465V
• Utilizes a compact 32-pin QFN package to minimize board space requirements

Applications

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

Procurement Notes

Verify the specific suffix and package variant against the official datasheet before ordering. Confirm that the 32-QFN footprint matches your PCB design constraints. Ensure the operating voltage aligns with your system's power rails. Check for any recent product change notifications regarding pinout or electrical characteristics updates.

Selection Notes

Select this component when a 2:8 fanout ratio is required for clock distribution. Consider the 750MHz frequency limit relative to your system's clock speed. Evaluate the 32-QFN package size against available board real estate. Verify compatibility with the 2.375V-3.465V supply range during system design.

Part Context

This part belongs to the ZL402xx series of clock buffers from Microchip Technology. These devices are engineered for low-jitter performance and flexible configuration options. The series supports various input/output standards and packaging types to accommodate different system architectures and timing requirements.

Replacement Considerations

Consult the official Microchip cross-reference guide for verified substitutes. Ensure any replacement maintains the 2:8 fanout ratio and 750MHz frequency capability. Verify package compatibility if using a direct pin-to-pin alternative.
