Caution
The oscillator constant is a reference value based on evaluation in specific environments by the
resonator manufacturer. If the oscillator characteristics need to be optimized in the actual
application, request the resonator manufacturer for evaluation on the implementation circuit.
Note that the oscillation voltage and oscillation frequency merely indicate the characteristics of
the oscillator. Use the internal operation conditions of the µPD780078Y Subseries within the
specifications of the DC and AC characteristics.
