Overview
The Microchip Technology part number 090-02789-011 is a commercial-grade atomic clock module belonging to the CSAC SA65 series. It features a 12-DIP package with 9 leads and measures 40.64mm x 35.31mm. The device operates on a 3.3V supply voltage and utilizes an atomic frequency standard for high precision timing. This component is designed for applications requiring stable reference clocks without reliance on external oscillators.
Feature Summary
- Integrates atomic frequency standard technology for superior stability
- Compact 12-DIP module form factor suitable for space-constrained designs
- Commercial temperature range operation capability
Applications
- Telecommunications base station synchronization
- Test and measurement equipment requiring precise timekeeping
- Navigation systems needing reliable frequency references
Procurement Notes
Verify that the specific revision of the CSAC SA65 module matches your design requirements, as atomic clock modules may have varying calibration states or firmware versions. Confirm that the 3.3V supply specification aligns with your system power architecture before finalizing orders.
Selection Notes
Select this module when high long-term frequency stability is required compared to traditional crystal oscillators. Ensure that the physical dimensions of the 12-DIP package fit within the designated footprint on the printed circuit board layout.
Part Context
This part belongs to Microchip's Compact Size Atomic Clock (CSAC) family, which replaces bulky vacuum tube atomic standards with solid-state alternatives. The SA65 series provides military-grade performance options, while this specific part number denotes the commercial variant intended for broader industrial use cases.
Replacement Considerations
Direct substitutes include other variants within the CSAC SA65 series, such as those with different temperature ratings or interface configurations. Cross-reference with similar atomic clock modules from competing manufacturers if supply constraints exist.
