New SA65 CSAC for Industrial and Military Applications Features High Precision and Low Power Consumption

Microchip Technology Inc. has announced its new SA65 Chip Scale Atomic Clocks to provide precise timing accuracy and stability in extreme environments. The SA65 has an operating temperature range of -40°C to 80°C and a storage temperature range of -55°C to 105°C. These SA65 CSAC are beneficial 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.

This CSAC features low power consumption of <120mW and a volume of <17cc. It provides RF and 1PPS outputs at standard CMOS levels, with short-term stability and maximum frequency change. The CSAC accepts a 1PPS input that may be used to synchronize the unit’s 1PPS output to an external reference clock with ±100ns accuracy.
