ZL30731LDG1

Overview

The ZL30731LDG1 is a clock synthesizer and jitter cleaner manufactured by Microchip Technology. It features one input channel and ten output channels, supporting a maximum output frequency of 750 MHz and a maximum input frequency of 1.25 GHz. The device accepts differential or single-ended inputs and provides CMOS or differential outputs. It operates on a supply voltage ranging from 1.8 V to 3.3 V and is housed in a VQFN-64 package designed for surface mount installation.

Feature Summary

• Supports 1-channel input with 10-output configuration
• Maximum output frequency of 750 MHz
• Accepts differential and single-ended input levels
• Provides CMOS and differential output levels

Applications

• 1588 timing card implementations
• SyncE network synchronizer systems
• General-purpose clock distribution networks

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct package and temperature grade specifications. Confirm lead times directly with authorized distributors as availability fluctuates. Ensure compliance with RoHS standards if required by the target application environment.

Selection Notes

Select this component when a single input source requires expansion into ten distinct clock signals. Verify that the system power budget accommodates the 1.8 V to 3.3 V operating range. Ensure the PCB layout supports the VQFN-64 package dimensions and thermal requirements for surface mount assembly.

Part Context

This part belongs to the ZL3073x series of network synchronizers. It is functionally related to models like the ZL30732BLDG1, which offers enhanced timing capabilities with two input channels and twenty outputs. Both devices share similar frequency ranges and packaging options within the same product family.

Replacement Considerations

The ZL30732BLDG1 serves as a compatible alternative within the same manufacturer lineup, offering increased I/O capacity. Cross-referencing pinouts and electrical characteristics with the official datasheet is necessary before substitution.
