OCXO, ultra-high stable crystal oscillator, the aircraft carrier among crystal oscillators

OCXO (Oven-Controlled Crystal Oscillator) constant temperature crystal oscillator is a high-precision frequency stabilization device, mainly used in applications requiring high-precision time and frequency, such as satellite navigation, communication equipment, scientific research and other fields. It uses a built-in temperature control system to maintain the crystal working at a constant temperature, thereby reducing the impact of temperature and improving frequency stability and accuracy.

What is the waveform of the crystal oscillator? Sine wave or square wave?

Regarding the crystal oscillator output waveform, I believe some people may think that there are only two waveforms, that is, the passive crystal oscillator output waveform is a sine wave, the active crystal oscillator output waveform is a square wave, and a small part is a sine wave. However, the square wave has the choice of non-differential and differential output; the sine wave has the choice of quasi-sine wave and peak-clipping sine wave.
