DTCXOs use a digitized voltage to readjust frequency accuracy and stability. The operating range for DTCXOs is at temperatures between -30 °C and +85 °C. In this temperature range they have a frequency stability that is 10exp-7. Aging is 0.5x10exp-6 per year. DTCXOs are offered in the frequency range between 1 MHz and about 50 MHz.
