Procurement Notes

Verify the specific suffix code against official Microsemi documentation to confirm the exact frequency and temperature rating. Ensure compatibility with existing circuit designs regarding supply voltage and load requirements. Cross-reference the datasheet for pinout configurations to prevent installation errors during integration.

Selection Notes

Select this model when superior long-term stability and low aging are critical compared to standard quartz oscillators. Consider the limited operating temperature range for environmental suitability. Evaluate space constraints as the DIP module form factor may require specific board layout considerations compared to surface-mount alternatives.

Part Context

This component belongs to the Quantum SA.45s CSAC family, representing Microsemi's atomic clock technology. These devices integrate chip-scale atomic clock functionality into compact modules. They serve as replacements for traditional oven-controlled crystal oscillators (OCXOs) where size and power consumption are constrained but performance remains paramount.

Replacement Considerations

Consult official substitution lists for direct equivalents. Verify that any alternative maintains the 5MHz frequency and CMOS output characteristics. Ensure thermal specifications match the application environment to avoid performance degradation.
