Caution The oscillator constants shown above are reference values based on evaluation in a specific
environment by the resonator manufacturer. If it is necessary to optimize the oscillator
characteristics in the actual application, apply to the resonator manufacturer for evaluation on
the implementation circuit. The oscillation voltage and oscillation frequency only indicate the
oscillator characteristic. Use the 78K0/KE1 so that the internal operation conditions are within
the specifications of the DC and AC characteristics.
