090-44350-12

Overview

The Microsemi Corporation 090-44350-12 is a high-precision atomic oscillator module operating at a nominal frequency of 10 MHz. It utilizes CMOS output logic and requires a 5V supply voltage with a maximum current consumption of 2.8A. The device features a frequency stability of ±1ppb and operates within a temperature range of -10°C to +75°C. Designed for robust performance, it includes holdover capabilities typical of the SA.35m series. The component is housed in a standard OCXO pinout module package measuring 2.000 inches by 2.000 inches.

Feature Summary

• High-precision atomic clock technology ensuring exceptional frequency stability
• Small form factor design compatible with standard OCXO pinouts
• Low power consumption characteristics relative to traditional atomic oscillators

Applications

• Telecommunications base station synchronization
• Navigation and positioning systems requiring precise timing
• Test and measurement equipment demanding stable reference frequencies

Procurement Notes

Verify the specific suffix code against official Microsemi documentation to confirm exact electrical parameters and holdover specifications. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm that the CMOS output levels match the receiving circuitry logic thresholds. Check for any updated environmental compliance certifications required for your region.

Selection Notes

Select this model when ultra-high frequency stability is critical for system integrity. Consider the thermal environment to ensure operation remains within the specified -10°C to +75°C range. Evaluate power budget constraints due to the 2.8A maximum current draw. Verify that the physical dimensions fit within the designated enclosure space.

Part Context

This component belongs to the SA.35m series of atomic oscillators from Microsemi. These modules are engineered for applications requiring long-term frequency accuracy without frequent recalibration. The series integrates atomic resonance principles into a compact module format, bridging the gap between crystal oscillators and larger atomic standards.

Replacement Considerations

Consult official Microsemi substitution guides for direct replacements. Cross-reference part numbers such as 090-44350-21 or 090-44350-31 only if they meet identical electrical and mechanical specifications. Verify pinout compatibility before installation.
