ZL40204LDF1

Overview

The ZL40204LDF1 is a clock buffer manufactured by Microchip Technology, designed for high-performance signal distribution. It features a 1:6 fanout configuration with LVPECL outputs and includes external termination capabilities. The device operates within a supply voltage range of 2.375V to 3.465V and supports maximum frequencies up to 750MHz. It is housed in a 32-QFN package (5x5mm) and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides 1-to-6 fanout buffering capability for precise clock signal distribution
• Supports LVPECL output standards with integrated external termination options
• Operates at high frequencies up to 750MHz for demanding timing applications

Applications

• High-speed data communication systems requiring low-jitter clock distribution
• Telecommunications infrastructure utilizing LVPECL signaling standards
• Test and measurement equipment needing precise multi-channel clock synchronization

Procurement Notes

Verify the specific suffix 'LDF1' against official Microchip documentation to confirm package type and tape-and-reel packaging details. Ensure compatibility with LVPECL input requirements and check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a single differential input must drive six LVPECL loads with minimal skew. Consider the 32-QFN footprint for board space constraints. Verify that the system power supply aligns with the 2.375V to 3.465V operating range and that thermal management suits the QFN package profile for the intended application environment.

Part Context

This part belongs to the ZL402xx series of smart clock buffers from Microchip Technology. These devices are engineered for flexible clock generation and distribution in complex digital systems. The series typically offers configurable inputs and outputs to support various logic families, ensuring robust timing integrity across diverse electronic designs.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives within the same family include variants with different fanout ratios or output types, such as the ZL40204LDG1, provided they meet the specific LVPECL and frequency requirements.
