Q value

      Q value, also known as "quality factor," reflects the quality of a crystal oscillator. A higher Q value indicates a smaller internal resistance, lower power consumption, and better stability. The quartz crystal resonator is used in the oscillator circuit as a resonant circuit. Its Q value is an important electrical parameter of the crystal oscillator, and it is closely related to the frequency stability of the crystal oscillator. As mentioned above, the higher the Q value of the crystal oscillator, the better the frequency stability.
