The operating principle of these oscillation circuits can be seen in fig 2 1.
Some of this is becoming more clear.
At the series resonance impedance is at a minimum below series resonance the crystal behaves as a cap above series resonance the the crystal behaves as an inductor with impedance increasing to the point until the capacitive and inductive reactances are equal impedance is maximized and we have reached the parallel resonant.
Ceralock find a broad range of applications such as automotive electronics communications personal computing and medical healthcare equipment.
Often coaxial resonators are implemented in oscillators as high quality factor high q inductors thereby creating a resonant circuit when paired with a capacitor or varactor diode.
Quartz crystals are more accurate and temperature stable than ceramic resonators.
In a ceramic resonator oscillator the inductor is replaced by a ceramic resonator taking advantage of the fact that the resonator becomes inductive between resonant and anti resonant frequencies.
It exhibits a piezoelectric characteristic that makes the ceramic material generate minute electrical energy when subjected to electromechanical expansion and compression.
The resonator or crystal itself has two connections.
Ok to add to my own post.
Crystal is the common term used in electronics for the frequency determining component a wafer of quartz crystal or ceramic with electrodes connected to it.
