oscillation but do not guarantee accuracy of the oscillation frequency. If the application circuit
requires accuracy of the oscillation frequency, it is necessary to set the oscillation frequency of the
resonator in the application circuit. For this, it is necessary to directly contact the manufacturer
of the resonator being used.
