Chip-scale Ultralow Power Timing Circuit
Accurate and reliable holdover time in total GPS denial
“Bridging the gap between crystal oscillators and CSAC”
Customer Needs
Modern sensing, navigation, cyber and autonomous systems depend on precise timing in contested environments when GPS signals are unavailable. This is especially problematic for battery-powered mobile/edge systems that cannot tolerate the added weight of supplemental batteries. Current solutions force a trade between Crystal oscillators (XO) that offer low power but lack stability and chip-scale atomic clocks (CSAC) that provide high stability but with significant power/cost penalties.
Our Solution
xSyncTM is a chip-scale, ultra-low power timing circuit designed to bridge the performance gap between crystal oscillators and chip-scale atomic clocks.
The solution provides resilient precision timing in GPS-degraded/denied environments.
xSyncTM is optimized for edge (mobile) platforms such as small UAS, distributed sensors, and autonomous systems, delivering improved timing stability while maintaining low SWaP-C and minimizing need for additional battery/weight.
