ZL30321GGG

Overview

The ZL30321GGG is a Stratum 3 network clock synchronizer manufactured by Microsemi (now Microchip Technology). It features 12 outputs with a maximum output frequency of 100 MHz and supports a maximum input frequency of 622.08 MHz. The device operates on 1.8 V and 3.3 V power supplies within an industrial temperature range of -40°C to +85°C. It is housed in a CABGA-100 package, designed for precise timing synchronization in telecommunications infrastructure.

Feature Summary

• Supports Stratum 3 network synchronization standards
• Provides 12 output channels with frequencies up to 100 MHz
• Accepts input signals up to 622.08 MHz
• Dual voltage operation at 1.8 V and 3.3 V

Applications

• SONET/SDH network synchronization
• Telecommunications base station timing
• Digital signal processing clock distribution

Procurement Notes

Verify the manufacturer status as Microsemi assets are managed by Microchip Technology. Confirm the specific datasheet revision and RoHS compliance details directly from official documentation before procurement. Ensure the CABGA-100 package compatibility with your PCB layout.

Selection Notes

Select this component when Stratum 3 accuracy is required for networks supporting inputs up to 622.08 MHz. The 12-output configuration suits complex clock distribution needs. Verify that the 1.8 V and 3.3 V supply rails match your system design constraints.

Part Context

This part belongs to the ZL303xx series of clock synchronizers. It shares functional similarities with models like the ZL30343GGG2 but differs in specific pinout or feature sets defined by its unique suffix. It is distinct from development tools like the ZLE30251.

Replacement Considerations

Check for direct substitutes within the ZL303xx family. Cross-reference pinouts and electrical specifications with similar parts such as the ZL30343GGG2 to ensure compatibility if sourcing alternatives.
