ZL40251LDG1

Overview

The ZL40251LDG1 is a clock buffer from the miSmartBuffer series by Microchip Technology. It features six output ports and integrates an external EEPROM interface for configuration storage. The device supports input frequencies up to 750 MHz and operates within a supply voltage range of 2.375 V to 3.465 V. It is housed in a 56-lead VQFN package with exposed pad, designed for surface mount applications across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates external EEPROM interface for persistent configuration data storage
• Provides six buffered clock outputs derived from a single input source
• Supports high-frequency operation up to 750 MHz input signal

Applications

• Clock distribution networks requiring multiple synchronized outputs
• Systems utilizing external non-volatile memory for device configuration
• High-speed digital circuitry requiring precise timing signals

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm that the received part matches the ZL40251LDG1 marking and packaging specifications. Ensure handling procedures comply with moisture sensitivity level requirements to prevent internal damage during assembly. Review the official datasheet for specific electrical characteristics and thermal performance guidelines before integration.

Selection Notes

Select this component when a design requires six distinct clock outputs driven by a single source with integrated configuration management capabilities. The inclusion of an external EEPROM interface distinguishes it from standard buffers lacking memory support. Consider the 56-lead VQFN package constraints for PCB layout and thermal dissipation requirements in dense assemblies.

Part Context

This part belongs to the miSmartBuffer family, which combines clock buffering functions with smart configuration features. Unlike basic fanout buffers, this model emphasizes configurability through external memory interfaces. It serves as a specialized solution for complex timing architectures where dynamic or persistent parameter storage is necessary alongside signal distribution.
