CRYSTAL OSCILLATOR, OCXO, TCXO stability comparison

Different applications will require different levels of performance. In some cases a crystal oscillator alone may be satisfactory, whereas for other applications a temperature compensated oscillator may be needed. For the highest specification requirements an oven controlled oscillator may be needed.

For applications that need even higher levels of stability, options including rubidium standards or some off-air GPS standards may provide the required levels of accuracy.
