Selection of ICs and circuit constants by frequency bands
*1: Necessary for preventing overtone oscillation and must be changed depending on the frequency band or the C
*2: Used to reduce excitation current of the crystal unit. Necessary for stable operation of small-sized crystal units.
*3: The optimum value differs with the values of load capacitance and Rd.
