The 27MHz crystal oscillator circuit is as shown in the figure. The R1, R2, R3 are the biasing resistor, the C6 is the bypass capacitor, the voltage division circuit is composed of the C1, C3, C4 and C2 to control the oscillation strength. The L1 is the high-frequency choking coil which has the filtering effect. The quartz crystal is in the parallel resonan..
