ZL30343GGG

Overview

The ZL30343GGG2 is a Stratum 3 network clock synchronizer manufactured by 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 supplies within an industrial temperature range of -40°C to +85°C. It is housed in a 100-pin CABGA package, designed for precise timing synchronization in telecommunications infrastructure.

Feature Summary

• Stratum 3 compliant clock synchronization
• 12 output channels with up to 100 MHz max frequency
• Supports input frequencies up to 622.08 MHz
• Dual voltage operation (1.8 V and 3.3 V)

Applications

• Telecommunications network synchronization
• SDH/SONET equipment timing
• Ethernet synchronous applications

Procurement Notes

Verify the specific suffix (e.g., GGG2) against the datasheet to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the CABGA-100 package footprint matches the PCB design requirements.

Selection Notes

Select this component when Stratum 3 accuracy is required for network timing. Compare the 100 MHz output limit against system needs. Verify compatibility with existing 1.8 V and 3.3 V power rails. Consider the 100-pin BGA package constraints for layout and thermal management.

Part Context

This part belongs to the ZL3034x family of clock synchronizers from Microchip. It is specifically optimized for network applications requiring high stability. The GGG2 suffix typically denotes a lead-free, RoHS-compliant variant in the CABGA package.

Replacement Considerations

Check for direct substitutes within the ZL3034x series. Verify pin-to-pin compatibility if replacing with other Microchip clock synchronizers. Ensure the replacement supports the same Stratum 3 specifications and output count.
