Abstract :
An oscillator design for high-stability SC-cut OCXOs is described that has high spectral purity. It uses an AT-cut resonator-filter to improve the oscillator phase noise and to suppress spurious-mode oscillations. The circuit details and phase noise performance are given, and we show the effect of the quartz driving current on long-term frequency aging
