The 44MHz quartz crystal oscillator circuit is as shown in figure 1. In order to get the high oscillation frequency, this circuit uses the frequency multiplication oscillation circuit. The L1 and C1 tune at 44MHz, the fundamental wave 22MHz is mistermination, so this is the short-circuit. The quartz crystal resonator uses the 22MHz resonator, it has the sensibility in the circuit, the partial voltage capacitance are C2 and C3. For the 22MHZ fundamental wave, the circuit is the three-point capacitance oscillation circuit, you can get the 22MHz oscillation signal from the emitter.
