Quartz crystal rectangular wave oscillator circuit
The quartz crystal rectangular wave oscillator circuit is mainly used in the new digital system clock-pulse generator. When the quartz crystal of this circuit is in the resonant state, the transmission amount is the largest, now the harmonic oscillation rate of the quartz crystal is the crystal's harmonic oscillation rate. Because ofthe high output impedance of LM111 and the isolation effect of C2, so the load of the quartz crystal is very small. The stability of the oscillation frequency is high. The circuit has the 100KHz rectangle wave output.
