Crystal operation
The equivalent electrical circuitfor a crystal is shown in Figure 1. Based on this model, we can find the reactance vs. frequency curve of a typical quartz crystal unit as depicted in Figure 2: To gain some insight into the operation of a crystal, let’s assume that the crystal is ideal and Rm is negligible. Hence, in the lower … See more We saw that crystals have two modes of resonance. At both fs and fa, the impedance of the crystal is resistive. At fs, the resistance is … See more The above discussion shows that a quartz crystal can oscillate at any frequency between the series resonant frequency (fs) and the anti-resonant frequency (fa) depending on the … See more Load capacitance refers to the amount of external capacitance that the crystal should “see” across its terminals. With series resonant oscillators, there are no reactive components in the oscillator feedback path … See more There are two technical terms in the crystal industry that can occasionally cause confusion: “parallel-resonant crystal” (or simply parallel crystal) and “series-resonant crystal” (or series crystal).
