090-44330-22

Overview

The Microsemi 090-44330-22 is a SA.33m Rubidium Clock module designed for high-stability timing applications. It operates at a frequency of 10 MHz with CMOS output levels. The device functions within an operating temperature range of -10°C to +75°C and requires a 5 V supply voltage. Maximum supply current is 2.8 A. The component utilizes a through-hole mounting type in a module package measuring 2.000 inches by 2.000 inches.

Feature Summary

• Provides stable 10 MHz timing reference using rubidium atomic clock technology
• Features CMOS output signal compatibility
• Designed for robust operation across industrial temperature ranges

Applications

• Telecommunications base station synchronization
• Test and measurement equipment requiring precise frequency standards
• Navigation and positioning systems

Procurement Notes

Verify the specific suffix designation against official Microsemi documentation to confirm exact frequency and enable pin configurations. Ensure that the procurement channel provides traceable origin data compliant with aerospace or industrial standards if required for the intended deployment environment.

Selection Notes

Select this module when a standalone, high-stability rubidium reference is required rather than a generic crystal oscillator. Consider the physical module dimensions and thermal management needs associated with the 2.8 A maximum current draw during initial design integration phases.

Part Context

This part belongs to the SA.33m series of rubidium clocks from Microsemi. It serves as a critical timing source for infrastructure where long-term frequency stability and low phase noise are mandatory requirements for system integrity.

Replacement Considerations

Consult official Microsemi cross-reference guides for compatible alternatives such as the SA.31m or SA.35m variants, ensuring electrical and mechanical specifications align with existing system constraints.
