the resonator under a specific environment.
If optimization of the oscillator characteristics is required for the actual application, apply to
the resonator manufacturer for evaluation on the mounting circuit.
The oscillation voltage and oscillation frequency only indicate the oscillator characteristics;
the oscillator must be used within the ratings of the DC and AC characteristics specified under
the internal operation conditions.
