090-02984-007

Overview

The Microchip Technology part number 090-02984-007 is a Chip Scale Atomic Clock (CSAC-SA45S) designed for high-stability timing applications. It operates with a maximum output frequency of 10 MHz and provides two CMOS outputs. The device requires a supply voltage between 3.2 VDC and 3.4 VDC, typically running at 3.3 V. It is housed in a 12-DIP module package with 9 leads and supports through-hole mounting. The component is rated for an operating temperature range from -10°C to +70°C and features radiation hardness up to 20 krad.

Feature Summary

• Integrated Chip Scale Atomic Clock (CSAC-SA45S) providing stable 10 MHz timing
• Dual CMOS output configuration for flexible system integration
• Radiation hardened design capable of withstanding 20 krad environments
• Operates on a standard 3.3 VDC power supply within specified limits

Applications

• Military and aerospace systems requiring radiation-tolerant timing sources
• Navigation and guidance systems needing high-frequency stability
• Secure communications infrastructure utilizing atomic clock precision

Procurement Notes

This component is classified as a factory special order item. Availability may be limited compared to standard catalog parts. Verification of current pricing, delivery schedules, and specific manufacturer ordering requirements is necessary before procurement. Confirm the exact suffix '007' matches the required 20 krad radiation specification during the ordering process.

Selection Notes

Select this model when a compact atomic clock solution is required for harsh environments. Ensure the system can accommodate the 3.2 VDC to 3.4 VDC input range and the 12-DIP footprint. Verify that the 10 MHz output frequency meets the system's clocking needs and that the -10°C to +70°C temperature range aligns with the operational environment.

Part Context

This part belongs to the SA.45s series of Chip Scale Atomic Clocks produced by Microchip Technology. These devices integrate the atomic cell and control electronics into a small form factor, replacing larger traditional atomic clocks. The 090-02984-007 variant specifically denotes the configuration optimized for radiation-hardened applications within this product line.

Replacement Considerations

No public confirmed substitute part numbers are available for direct replacement. Due to the specialized nature of the CSAC-SA45S and its specific radiation hardening rating, alternative components must be evaluated based on functional equivalence rather than direct pin-to-pin substitution.
