Completed Technology Project

Project Introduction

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