Aerospace/Military/Defence Product of the Year
Product Name: Microchip SA65 CSAC – Chip Scale Atomic Clock
Company: Microchip Technology
Microchip’s SA65 Chip Scale Atomic Clock (CSAC) provides wider operating temperatures, faster warm-up and improved frequency stability in extreme environments
Advanced military platforms, ocean-bottom survey systems and remote sensing applications all require precise timing for mission success. CSACs ensure stable and accurate timing even when Global Navigation Satellite Systems (GNSS) time signals are unavailable.
Microchip’s SA65 CSAC for military and industrial systems features ultra-high precision and low power consumption 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 to 80 degrees Celsius (oC) 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.
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. The SA65 is form-, fit- and function-compatible with the SA.45s, which minimizes risk and redesign costs for the system developer while improving performance and environmental insensitivity.
