Crystals previously mentioned thirty MHz (up to >200 MHz) are commonly operated at series resonance the place the impedance seems at its bare minimum and equal on the collection resistance. For these crystals the sequence resistance is specified ( It's important to note that oscillators have a critical parameter—the resonant https://bookmarknap.com/story9251190/helping-the-others-realize-the-advantages-of-smd-crystal-oscillators
