Caution The oscillator constant is a reference value based on evaluation under a specific environment by
the resonator manufacturer.
If optimization of oscillator characteristics is necessary in the actual application, apply to the
resonator manufacturer for evaluation on the implementation circuit.
The oscillation voltage and oscillation frequency indicate only oscillator characteristics. Use the
µ
PD789860 and 789860(A) so that the internal operating conditions are within the specifications
of the DC and AC characteristics.
