Procurement Notes

Verify the specific ordering suffix to confirm the AT disable state and output type. Confirm that the SA.31m series designation matches the required rubidium clock specifications. Check for any environmental certifications or compliance documents relevant to the deployment region. Ensure the 5V supply requirement aligns with the system power architecture. Validate the operating temperature range against the intended installation environment.

Selection Notes

Select this model when atomic frequency stability is critical for system performance. Consider the 2.8A current draw for power budget calculations. Evaluate the -10°C to 75°C range against ambient conditions. Compare against other SA.31m variants if different output types or frequencies are needed. Ensure compatibility with existing CMOS input stages in the target design.

Part Context

This part belongs to the Microsemi SA.31m series of rubidium clocks. These devices are designed for high-performance timing applications. The series provides stable frequency references using rubidium vapor cell technology. Other models in the family may offer different frequencies or output formats.

Replacement Considerations

Check for direct replacements within the SA.31m series. Verify pinout and electrical compatibility before substitution. Consult Microsemi documentation for updated product recommendations if this item is obsolete.
