Space Chip Scale Atomic Clock (CSAC)
SA.45s
Overview
Pairing Radiation Tolerance with the CSAC's Low Power and High performance - brings the accuracy and stability of atomic clocks to Commercial Space applications.
The Microsemi Commercial Space CSAC is the world's first commercially available radiation-tolerant chip scale atomic clock, providing the accuracy and stability of atomic clock technology while achieving true breakthroughs in reduced size, weight and power consumption. This product is ideal for Low Earth Orbit applications. (Part Number 090-02984-007)Space CSAC Key Features
