Parallel crystal oscillator

  
Actual typical crystal oscillator circuit as shown in FIG. The three-point oscillator circuit to meet the original composition is for capacitance feedback oscillator. When the
Parallel crystal oscillator - schematic

oscillator oscillation frequency of the series and parallel resonant frequency of the resonant frequency of the crystal is between crystal was emotional, it may oscillate oscillator. This circuit is commonly referred to Pierce (Pierce) oscillator, called parallel fork type crystal oscillator. Transistors 3DG6C, other parameters as shown 21-31 in FIG. Pierce oscillator frequency by the c1, G, C3 decision circuit and crystal composition. Parallel crystal oscillation frequency of between A series resonant frequency and the parallel resonant circuit of quartz crystal frequency.
