Crystals previously mentioned 30 MHz (approximately >two hundred MHz) are commonly operated at series resonance the place the impedance seems at its bare minimum and equivalent for the collection resistance. For these crystals the series resistance is specified ( SMD crystals incorporate exceptionally small period sound, which ends up in https://wildbookmarks.com/story19163322/the-fact-about-smd-crystal-oscillators-that-no-one-is-suggesting
