If the temperature-payment circuit matched a crystal's temperature curve precisely, the oscillator's frequency would continue being continual given that the temperature modified. It's not obtainable in the true world as a result of variability of crystals available along with the thermistor coefficients accessible. Available with three.3V source voltage, the GTXO-C31L https://temperaturecompensatedcry03715.blogolize.com/details-fiction-and-temperature-compensated-crystal-oscillators-70255897
