      The output frequency of the PX-570 crystal oscillator as a function of temperature is shown in Figure 2. The oscillator operated successfully throughout the entire test temperature range of -125 °C to +230 °C with very slight variation in its output frequency, most notably at the extreme high temperatures.

      In this simple circuit, the crystal determines the frequency of oscillations and operates on its series resonant frequency giving a low impedance path between output and input. There is a 180° phase shift at resonance, making the feedback positive. The amplitude of the output sine wave is limited to the maximum voltage range at the Drain terminal.

      A crystal is an electromechanical resonator which resonates at its natural frequency when excited with electrical energy. Figure 8 shows a conventional crystal oscillator circuit. The equivalent circuit of a crystal consists of a series RLC circuit with a parasitic parallel capacitor Cp. The frequency of oscillation is determined by Lm and Cm.

      Crystal Oscillator Information XO - Non-Compensated Crystal Oscillators Non-compensated crystal oscillators employ no correction or control to reduce the frequency variation over temperature beyond the intrinsic crystal stability. However, 'non-compensated' is a bit of a misnomer since AT-cut crystals exhibit an S-shaped cubic frequency vs temperature curve which can hold the frequency ...
