Crystals over thirty MHz (up to >200 MHz) are commonly operated at collection resonance in which the impedance seems at its bare minimum and equal to your collection resistance. For these crystals the sequence resistance is specified ( It's important to notice that oscillators Have got a vital parameter—the resonant https://singnalsocial.com/story4016176/helping-the-others-realize-the-advantages-of-smd-crystal-oscillators
