ZL40200LDF1

Overview

The ZL40200LDF1 is an LVPECL clock fanout buffer manufactured by Microchip Technology. It features two identical output clock drivers capable of operating at frequencies up to 750 MHz. The device accepts differential or single-ended inputs and supports multiple input formats including LVDS, CML, HCSL, and LVCMOS. It operates on a supply voltage range of 2.375V to 3.465V and functions within a temperature range of -40°C to 85°C. The component is housed in a 16-VFQFN Exposed Pad package with dimensions of 3x3 mm.

Feature Summary

• Provides two precision LVPECL outputs for clock distribution
• Accepts both differential and single-ended input signals
• Supports multiple input logic standards including LVDS, CML, and HCSL

Applications

• High-speed clock distribution networks
• Data communication systems requiring precise timing
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'LDF1' against the official Microchip datasheet to ensure correct pinout and electrical characteristics. Confirm that the 16-VFQFN exposed pad footprint matches your PCB design requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the supply voltage range aligns with your system's power delivery network.

Selection Notes

Select this component when a low-jitter LVPECL buffer is required for high-frequency applications up to 750 MHz. It is suitable for systems needing to split a single clock source into two matched LVPECL paths. Consider the input format compatibility if your source signal is not inherently LVPECL, as the device supports various input types. Evaluate the thermal performance within the specified -40°C to 85°C range for your operational environment.

Part Context

The ZL40200 series consists of LVPECL clock buffers designed for high-performance timing applications. This specific model provides a 1:2 fanout ratio, making it ideal for distributing reference clocks to multiple receivers. The device is part of Microchip's portfolio of clock management solutions, emphasizing signal integrity and low phase noise in demanding electronic systems.

Replacement Considerations

Consult the official Microchip cross-reference list for verified substitutes. Generic equivalents may not match the specific 750 MHz frequency limit or LVPECL output characteristics. Verify pin-to-pin compatibility before considering alternative part numbers from other manufacturers.
