subject: Advantages and Disadvantages of Oven Controlled Crystal Oscillators-OCXOs [print this page] The OCXOS operating temperature is required several degrees higher than the highest ambient temperature in which OCXO has to operate by which the oven may maintain good control. There are disadvantages associated with high oven temperature operation. First, the crystal's frequency vs. temperature characteristic is sharper with the higher turnover crystal. Second one is more important, crystal aging degrade with an increasing temperature. That's why it is important while designing an OCXO. It should be low as practicable, but it must be high to drive good control at the maximum ambient operating temperature.
