ZL40203LDG1

Overview

The ZL40203LDG1 is a clock fanout buffer manufactured by Microchip Technology, designed for high-speed signal distribution. It provides a 1:4 input-to-output ratio with LVPECL outputs and supports a maximum frequency of 750 MHz. The device accepts multiple differential and single-ended input formats, including CML, HCSL, LVCMOS, LVDS, and LVPECL. It operates on a supply voltage range of 2.375 V to 3.465 V and functions within an industrial temperature range of -40°C to +85°C. The component is housed in a 16-VFQFN package with an exposed pad.

Feature Summary

• 1:4 Fanout Buffer Configuration
• Maximum Frequency of 750 MHz
• LVPECL Output Interface
• Multi-Format Input Support (CML, HCSL, LVCMOS, LVDS, LVPECL)
• 16-VFQFN Package

Applications

• High-speed clock distribution networks
• Data communication systems requiring low skew buffering
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix 'LDG1' against the manufacturer's current datasheet to confirm packaging details, as distributor listings may vary between tray and tape-and-reel options. Ensure compatibility with the required input signal format and output load conditions before integration into the design.

Selection Notes

Select this component when a 1:4 split is required for LVPECL signals up to 750 MHz. Consider the ZL40203LDF1 variant if tape-and-reel packaging is preferred over the standard tray configuration. Verify that the system power supply remains within the 2.375 V to 3.465 V operating range.

Part Context

This part belongs to the ZL40203 family of clock buffers from Microchip Technology. It shares core specifications with variants such as the ZL40203LDF1, differing primarily in packaging type. The family is engineered for applications demanding precise clock timing and signal integrity in dense electronic environments.

Replacement Considerations

The ZL40203LDF1 serves as a direct functional substitute, offering identical electrical characteristics but utilizing tape-and-reel packaging instead of trays. Cross-reference pinouts and thermal requirements to ensure mechanical compatibility during replacement.
