No.4 "The Oscillation frequency measurement" - IC and crystal units characterization -
What is the oscillation frequency and the frequency correlation? The oscillation frequency refers to the actual frequency of the oscillation circuit when the crystal is implemented. The oscillation frequency is mainly determined by the characteristics of the crystal unit, but the characteristics of the microcomputer, external load capacitance, and stray capacitance of the PCB must be taken into consideration. We would like to explain how to measure the oscillation frequency for a crystal unit and the frequency correlation.
