Crystals above thirty MHz (nearly >200 MHz) are typically operated at sequence resonance in which the impedance appears at its minimal and equal to the series resistance. For these crystals the collection resistance is specified ( Attributes several different frequencies, crystal ageing, and operating temperature ranges that could suit precise https://bookmarkingbay.com/story18988406/the-fact-about-smd-crystal-oscillators-that-no-one-is-suggesting
