Suitable for military and industrial systems, the new SA65 Chip Scale Atomic Clock (CSAC) from Microchip enables designers to meet wide operating temperatures, fast warm-up, and improved frequency stability requirements in extreme environments. Featuring ultra-high precision and low power consumption, this new device is form-, fit- and function-compatible with the SA.45s, and helps in improving performance and environmental insensitivity.
The SA65 CSAC is an embedded timing solution with improved environmental ruggedness, has an operating temperature range of -40 to 80 degrees Celsius, and a storage temperature range of -55 to 105 oC. The warm-up time of two minutes at -40 oC is 33% faster than that of the SA.45s. It is the low-power commercial atomic clock that provides precise timing for portable and battery-powered applications requiring continuous operation and holdover in GNSS-denied environments.
This is a highly-portable solution 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.
