Quartz crystal RMS operating current is critical to long-term stability, temperature coefficient and reliability. Accurate determination of RMS crystal current, especially in micropower types, is complicated by the necessity to minimize introduced parasitics, particulary capacitance, which corrupt crystal operation. This video shows why PC clocks are invariably wrong, and how engineers can surmount the extreme measurement challenge involved in solving the problem.
