A Stable, Extreme Temperature, High Radiation, Compact. Low Power Clock Oscillator for Space, Geothermal, Down-Hole & other High Reliability Applications

Efficient and stable clock signal generation requirements at extreme temperatures and high radiation are not met with the current solutions. Chronos Technology proposes to evaluate RTXO as a new and comprehensive solution that simultaneously addresses the requirements of a reliable clock source in extreme environments. RTXO utilizes the larger band-gap, smaller intrinsic carrier concentration, high radiation tolerance and extreme temperature capabilities of Silicon Carbide (Sic-4H) semiconductor technology. We will validate (thru FEA & other analysis) the trade-offs of advanced, high-Q Quartz and Gallium orthophosphate resonator material (in thickness shear mode resonance), configuration, processing, electronic interface and a matched mechanical support structure. Packaging technology approach addresses the unique needs of integrating an environmentally sensitive high-Q resonator operating in the same environment as the rest of the components. Suitable processes will be evaluated to yield reliable and repeatable manufacturing of RTXO as a viable and real life solution. All the different elements and processes identified in this solution must comply and dovetail in order for a compact, robust, mono-metallically interconnected and hermetically sealed housing configuration (interconnection) to encapsulate the assembly. RTXO technical objective is to deliver exceptional performance over temperature ranges from -100?C and exceeding 400?C and radiation exceeding 300Krad (TID).
