090-02984-001

Overview

The Microchip Technology part number 090-02984-001 is a Chip Scale Atomic Clock (CSAC) from the SA.45s series, designed for high-stability timing applications. It operates at a fixed frequency of 10 MHz and provides two CMOS outputs. The device requires a supply voltage ranging from 3.2 VDC to 3.4 VDC, with a nominal operating voltage of 3.3 V. It is rated for an industrial temperature range of -10°C to +70°C and utilizes through-hole mounting in a bulk package configuration.

Feature Summary

• Integrates atomic clock technology within a chip-scale form factor for superior frequency stability.
• Provides dual CMOS output signals for flexible system integration.
• Operates on a standard 3.3V power supply with defined tolerance limits.

Applications

• Navigation systems requiring precise timekeeping
• Telecommunications infrastructure synchronization
• Military and aerospace electronic systems

Procurement Notes

Verify the specific option suffix against official Microchip documentation to ensure compatibility with radiation hardness or environmental requirements. Confirm that the through-hole package style matches your PCB layout constraints. Cross-reference the datasheet for any recent product change notices affecting the SA.45s series specifications before finalizing procurement orders.

Selection Notes

Select this component when ultra-low jitter and long-term frequency stability are critical compared to traditional crystal oscillators. Ensure the design accommodates the 3.3V supply requirement and the physical dimensions associated with the through-hole package. Consider the operational temperature range limits when deploying in environments exceeding standard industrial boundaries.

Part Context

This part belongs to the SA.45s family of Chip Scale Atomic Clocks manufactured by Microchip Technology. These devices replace bulky vacuum tube atomic clocks with solid-state alternatives, offering significant size and weight reductions while maintaining atomic-level precision for timing-critical applications.

Replacement Considerations

Consult Microchip's official obsolescence notices for direct replacements. Verify pinout and electrical compatibility if considering alternative CSAC models from other manufacturers.
