WebMay 20, 2024 · In addition, capacitors in the external circuitry provide some damping effect and thus stabilize the frequency. A series resistor is present in the external oscillator circuitry to limit the current flowing through the crystal. The selection of the series resistor depends on the piezoelectric crystal used and the required resonance frequency. Crystals undergo slow gradual change of frequency with time, known as aging. There are many mechanisms involved. The mounting and contacts may undergo relief of the built-in stresses. Molecules of contamination either from the residual atmosphere, outgassed from the crystal, electrodes or packaging materials, or introduced during sealing the housing can be adsorbed on the crystal surface, changing its mass; this effect is exploited in quartz crystal microbalances. Th…

WebThe series resistor, Rs, is used to limit the amount of drive current to the crystal supplied from the XTAL pin of the inverter. It is very easy to overdrive the crystal. Therefore, the series resistor must be picked with care. Low-frequency oscillators are very susceptible to problems caused by being overdriven. The WebMay 6, 2024 · You can build a crystal or resonator oscillator with logic inverters, but the relevant pins on an AVR are specifically supposed to be an oscillator circuit, and there is no reason to assume that it isn't already biased properly (or designed as "not digital"), unless the datasheet or app note specifically says so.
