Caution:
The oscillator constants and oscillator voltage range indicate conditions for stable
oscillation, but do not guarantee oscillation friquency accuracy. If oscillation frequency
accuracy is required for actual circuits, it is necessary to adjust the oscillation frequency
of the oscillator in the actual circuit. Please contact directly the manufacturer of the
resonator to be used.
