Crystal oscillators can be about ten times better than the LC oscillator. The integrated circuit made the frequency synthesizer possible, but a stable source is still necessary for the synthesizer. The quartz crystal was the original stable source. Today, there are oscillator sources much more stable than the quartz crystal.

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 ...

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 ...

A sub-threshold crystal oscillator design. A mixed-signal scheme that obtains the TG and TD of a crystal oscillator. A control scheme where amplifier can be disabled, yet oscillation can be retained utilizing the stored energy in the crystal resonator. A ULP level converter circuit for the conversion of crystal output at higher digital voltage

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.
