Chip-scale atomic clock for military and industrial systems

25 August 2021 Analogue, Mixed Signal, LSI

Advanced military platforms, ocean-bottom survey systems and remote sensing applications all require precise timing for mission success. Chip-scale atomic clocks (CSACs) ensure stable and accurate timing even when global navigation satellite system (GNSS) time signals are unavailable. Helping industrial and military system designers to meet this requirement, Microchip Technology announced its new SA65 CSAC, providing precise timing accuracy and stability in extreme environments.

The device is an embedded timing solution with improved environmental ruggedness, delivering higher performance than the previous SA.45s CSAC, including double the frequency stability over a wider temperature range and faster warm-up at cold temperatures. The SA65 has an operating temperature range of -40°C to 80°C and a storage temperature range of -55°C to 105°C. The warm-up time of two minutes at -40°C is 33% faster than that of the SA.45s.

Together, these SA65 CSAC performance improvements benefit designers of highly portable solutions for military applications such as Assured Position, Navigation and Timing (A-PNT) and command, control, communications, computers, cyber, intelligence, surveillance and reconnaissance (C5ISR) requiring precise frequencies generated by a low size, weight and power (SWaP) atomic clock. Improvements such as fast warm-up to frequency after cold start, temperature stability over a wide operating range and frequency accuracy and stability enabling extended operation while GNSS is denied, help to ensure mission success in conflict environments.

The SA65 CSAC is the world’s lowest-power commercial atomic clock and provides precise timing for portable and battery-powered applications requiring continuous operation and holdover in GNSS-denied environments. It is form-, fit- and function-compatible with the SA.45s, which minimises risk and redesign costs for the system developer while improving performance and environmental insensitivity.
