090-44350-11

Overview

The Microsemi 090-44350-11 is a high-precision atomic clock oscillator operating at 10 MHz with CMOS output. It features a frequency stability of 10 ppb and operates within a temperature range of -10°C to 75°C. The module requires a 5V supply voltage and draws a maximum current of 2.8A. Designed for through-hole mounting, it measures 2.000 inches by 2.000 inches in size with a maximum height of 0.740 inches. This component belongs to the SA.35m series and utilizes a standard OCXO pinout configuration.

Feature Summary

• High-precision atomic clock performance
• Small form factor with standard OCXO pinout
• Low power consumption design

Applications

• Telecommunications infrastructure requiring precise timing
• Test and measurement equipment needing stable reference frequencies
• Navigation systems demanding high frequency stability

Procurement Notes

Verify the specific suffix code to ensure compatibility with required holdover specifications and lock times. Confirm that the 2.8A maximum current draw aligns with the system power budget. Check for obsolete status or lifecycle changes as availability may be limited. Ensure the through-hole mounting type fits the target PCB layout constraints.

Selection Notes

Select this model when superior long-term frequency stability compared to TCXOs is required. Consider the higher current consumption relative to other oscillators during power planning. Verify that the 10 MHz frequency matches the system clock requirements. Evaluate the physical dimensions against available board space for the module package.

Part Context

This component is part of the Microsemi SA.35m series of rubidium atomic clocks. These devices are engineered to provide exceptional frequency accuracy and stability over time and temperature variations. The series is designed for applications where traditional crystal oscillators cannot meet stringent timing requirements.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if other suffixes within the 090-44350 series offer compatible electrical characteristics or form factors for direct replacement.
