WebJun 16, 2024 · The crystal will oscillate at a frequency where it exhibits a reactance of 1 2πf LCL 1 2 π f L C L. Hence, a given load capacitance restricts the crystal to oscillate at a specific point between f s and f a. If we change the load capacitance, a different oscillation frequency will be obtained. WebCrystals are available is different precisions, +/-20 ppm is more or less standard, for 10 ppm you'll pay more. Also, this is basic precision. This frequency may deviate depending on …

WebTotal tolerance of the crystal mainly depends on the following parameters like: •Frequency tolerance at 25ºC •Frequency stability over the operating temperature •Aging of the crystal You can find these parameters mentioned as ppm (parts per million) in the respective crystal datasheets. WebIt is the sum of calibration tolerance and temperature stability. Drive Level For high frequency AT-cut crystals, the maximum recommended drive level for reasonable stability is in the region of 1-2 milliwatts, but for better results is should be limited to 0.5mW or less. iob main branch
