What are the Important Parameters of Common SMT Crystal Oscillator?

SMD crystal oscillator is divided into passive crystal oscillator and active crystal oscillator. Generally speaking, the common passive SMD crystal oscillator is represented by "SMD", while the active SMD crystal oscillator is represented by OSC. The reason why the latter uses OSC is mainly to distinguish it from passive crystal oscillator in terms of name, so as to avoid confusion. Passive crystal oscillator is often called quartz crystal resonator, crystal and so on.
