Frequency-temperature and aging performance of microcomputer compensated crystal oscillators
Evaluation of five samples of the microcomputer-compensated crystal oscillator built during a development program has verified the feasibility of achieving frequency vs. temperature stability of +or-5*10/sup -8/, aging of 1*10/sup -10//day, and hysteresis of no worse than +or-3*10/sup -8/, with an input power of 45 mW. A simulated compensation was performed on several samples of each of two dual-mode oscillator designs. One design uses a lateral-field resonator and the other uses a conventional thickness-field resonator. The frequency could be compensated to better than +or-2*10/sup -8/ for a -55 degrees C to +85 degrees C temperature range for both designs.<>
