090-02984-004

Overview

The Microsemi 090-02984-004 is a SA.45s CSAC atomic oscillator operating at 10.24 MHz with CMOS output voltage levels and a 3.3V supply requirement. It utilizes a 12-DIP module package featuring 9 leads for connection. This component integrates atomic frequency standard technology to provide high stability timing signals within a compact form factor suitable for precision electronic applications.

Feature Summary

• Integrates cesium atomic frequency standard technology for long-term stability
• Provides precise 10.24 MHz output signal via CMOS interface
• Operates on a single 3.3V power supply rail

Applications

• Telecommunications base station synchronization
• Navigation and positioning systems requiring high accuracy
• Test and measurement equipment calibration

Procurement Notes

Verify the specific ordering suffix and revision level against the manufacturer's current documentation to ensure compatibility with system requirements. Confirm that the 12-DIP package configuration matches the intended PCB layout constraints. Check for any recent product change notifications or end-of-life status updates from Microchip Technology before finalizing procurement plans.

Selection Notes

Select this component when application demands exceed the stability of traditional crystal oscillators but require a smaller footprint than standalone atomic standards. The 3.3V CMOS output simplifies interfacing with digital logic circuits. Ensure thermal management strategies account for the self-heating effects inherent in atomic oscillator designs during continuous operation.

Part Context

This part belongs to the SA.45s series of Chip-Scale Atomic Clocks (CSAC) manufactured by Microsemi, now part of Microchip Technology. These devices represent a class of miniaturized atomic oscillators designed to replace bulkier traditional atomic standards while maintaining superior frequency stability over temperature and time variations compared to quartz-based alternatives.

Replacement Considerations

Consult official Microchip cross-reference guides for direct replacements. Verify pinout compatibility and electrical specifications if considering alternative atomic oscillator models from other manufacturers.
