ZL50064QCG1

Overview

The ZL50064QCG1 is a high-performance, radiation-tolerant clock generator and jitter attenuator manufactured by Microchip Technology. Designed for space-grade applications, this component integrates a Phase-Locked Loop (PLL) to provide precise frequency synthesis and signal conditioning. It supports multiple output configurations with low-jitter performance, ensuring reliable timing in harsh radiation environments. The device operates within a specified voltage range and is housed in a robust surface-mount package suitable for automated assembly.

Feature Summary

• Radiation tolerance designed for space and high-reliability environments
• Integrated PLL for low-jitter clock generation and attenuation
• Multiple output configuration options for flexible system integration

Applications

• Spacecraft communication systems requiring radiation-hardened timing
• Satellite payload data processing units
• High-reliability aerospace navigation equipment

Procurement Notes

Verify the specific suffix 'QCG1' against the official Microchip datasheet to confirm radiation hardness level and operating temperature range. Ensure compatibility with existing PCB footprints and power supply requirements before procurement. Check for obsolescence notices or last-time-buy dates as space-grade components may have limited production runs.

Selection Notes

Select the ZL50064QCG1 when radiation tolerance is a critical design constraint. Compare its jitter specifications and output drive capabilities against standard commercial alternatives if environmental conditions permit. Confirm that the required input frequencies and output ratios are supported by the internal PLL architecture documented in the technical specifications.

Part Context

This part belongs to Microchip's ZL series of programmable clock generators. The 'Q' prefix typically denotes qualification for extended temperature ranges or specific reliability standards. The ZL50064 variant is engineered for applications demanding high stability and resilience against single-event effects and total ionizing dose exposure common in orbital missions.

Replacement Considerations

Direct replacements must match the radiation tolerance and pinout. Verify if newer revisions of the ZL50064 family offer improved specs. Cross-reference with other radiation-hardened clock generators from qualified vendors if availability is constrained.
