090-44330-31

Overview

The Microsemi Corporation 090-44330-31 is a high-precision atomic CMOS oscillator module designed for applications requiring exceptional frequency stability. Operating at a nominal frequency of 10 MHz, this component utilizes an internal atomic clock mechanism to maintain accurate timekeeping and signal generation. The device functions with a standard operating supply voltage of 5 V and features a CMOS output interface suitable for digital logic integration. It is housed in a through-hole module package with dimensions of 2.000 inches by 2.000 inches (50.80 mm x 50.80 mm). The unit supports an extended operating temperature range from -10°C to +75°C, ensuring reliable performance in various industrial environments.

Feature Summary

• Integrates a high-precision atomic clock mechanism for superior long-term frequency stability and accuracy compared to standard crystal oscillators.
• Delivers a clean CMOS output signal compatible with standard digital logic families, simplifying interface design.
• Utilizes a compact standard OCXO pinout form factor, facilitating easy replacement and integration into existing equipment layouts.

Applications

• Telecommunications base stations requiring precise timing synchronization
• Test and measurement instruments needing stable reference frequencies
• Navigation and GPS systems demanding high-accuracy clock sources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required holdover specifications and environmental ratings. Confirm that the module package dimensions and pinout align with the target PCB footprint before procurement. Cross-reference the operating temperature range with the intended application environment to guarantee reliability under thermal stress conditions.

Selection Notes

Select this component when application requirements exceed the stability limits of standard TCXO or OCXO technologies. The atomic nature of the oscillator makes it suitable for scenarios where long-term drift must be minimized without external correction. Consider the physical size and power consumption relative to system constraints, as atomic modules typically differ significantly from smaller surface-mount alternatives.

Part Context

This part belongs to the Microsemi atomic oscillator family, which provides industry-leading stability for critical infrastructure. These modules are engineered to replace aging rubidium or cesium standards in space-constrained applications. The 090 series represents a standardized form factor solution, allowing designers to upgrade timing performance without redesigning mechanical enclosures or major circuit interfaces.

Replacement Considerations

Direct replacements may include other models within the Microsemi 090 series, such as the 090-44330-32, provided the output type and frequency match. Verify that substitute parts meet the same holdover performance standards and physical mounting requirements to ensure seamless integration without mechanical modifications.
