Summary of SA65 CHIP SCALE ATOMIC CLOCK FOR IMPROVED ENVIRONMENTAL RUGGEDNESS
The SA65 Chip Scale Atomic Clock (CSAC) from Microchip is a rugged, ultra-precise, low-power timing solution for military and industrial systems. It is form-, fit- and function-compatible with the SA.45s, operates from -40 to 80°C (storage -55 to 105°C), offers 120 s warm-up at -40°C, 120 mW power, 17 cm3 volume, 35 g weight, and provides 10 MHz and 1 PPS CMOS outputs, RS-232 control, and strong stability and aging characteristics for GNSS-denied A-PNT and C5ISR applications.
Parts used in the SA65 Chip Scale Atomic Clock:
- SA65 Chip Scale Atomic Clock module
- 10MHz square wave CMOS output
- 1PPS CMOS output
- 1 PPS input for synchronization
- RS-232 interface for monitoring and control
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.
