WebApr 3, 2008 · circuit. Just putting a capacitor in parallel with the crystal will. bring the resonant frequency to the correct value, but won't allow the. oscillator to work. The other question is about the ESR indicated in the crystal datasheet. If this ESR indicated in the datasheet of the crystal is slightly higher. WebThe ESR value is an electrical representation of losses of the mechanical crystal oscillation. A larger crystal loses less energy during oscillation, and this results in a lower ESR value. Small crystals, especially SMD crystals, tend to have higher ESR. A higher ESR value reflects the higher losses of a crystal.
