Microchip Advances Space-Grade Timing with Enhanced Radiation Tolerance and Extended Temperature Performance

Microchip Technology expanded its atomic clock portfolio with the radiation-tolerant Space CSAC-SA65 to support New Space market demands for smaller, less expensive hardware.
The device extends radiation tolerance to at least 30 kRad & operates in temperature ranges from –40°C to +80°C.
It consumes less than 120 mW & occupies less than 17 cc of volume, offering a compact alternative for size-, weight-, & power-constrained satellite designs.
Built-in 1 PPS capabilities enable synchronization while atomic stability allows extended operation without reliance on external GNSS signals.
Manufactured as a Commercial Off-The-Shelf product using radiation-tolerant components, it offers shorter lead times & lower costs than traditional space-grade oscillators.
The CSAC-SA65 is designed for Low Earth Orbit missions & supports applications including timing, frequency control, assured positioning, navigation, timing, & satellite cross-linking.
Development is supported by Microchip's Clockstudio software & a CSAC Developer Kit.
The product (part number 090-02789-007) is available for purchase through sales representatives or authorized distributors.
