Crystal oscillator - Wikipedia
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.

The oscillator's structural response is similar to a cantilever beam. Resonant excitation may occur during shock and vibration. High stress levels may develop in the crystal and in the leads as a result. Figure A-2. Crystal Oscillator Mounted on Circuit Board, Improved Mounting Method. The oscillator is bent over so that it is parallel to the ...

The ability of crystal oscillators to provide an extremely stable clock is the primary reason for its prevalence. However, a crystal oscillator consumes significant amounts of power to operate, which increases exponentially with frequency Figure 1 shows the power consumption of a crystal oscillator with respect to frequency. Figure 1.

The Pierce oscillator is a crystal oscillator that uses the crystal as part of its feedback path and therefore has no resonant tank circuit. The Pierce Oscillator uses a JFET as its amplifying device as it provides a very high input impedance with the crystal connected between the output Drain terminal and the input Gate terminal as shown below.

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 ...

If the circuit is tuned to one of the harmonic frequencies of the crystal (overtones), then we can produce stable outputs much higher than the 10 MHz limit of the crystal itself. This type of circuit is said to be operating in overtone mode. A Colpitts oscillator can be modified into a crystal-controlled oscillator (CCO) as shown in Figure 14.
