Caution
The oscillation circuit constants and oscillation voltage range indicate conditions for stable
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
in the application circuit. For this, it is necessary to directly contact the manufacturer of the
resonator being used.
