Note:
*1.The operating frequency is a yardstick value derived form the crystal used for PTI characteristics authentication. However, the
oscillator for frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and
mounting conditions, so the oscillation of components must be carefully evaluated.
*2. The 3rd overtone frequency range uses an external resistor to set the cutoff frequency.
