The function of crystal oscillator is to provide basic clock signal for the system. Generally, one system shares one crystal oscillator to keep the parts synchronized. Some communication systems have different fundamental frequencies and radio frequencies using different oscillators, while maintaining synchronization by electronically adjusting the frequency.
The crystal oscillator is usually used in conjunction with the PLL circuit to provide the clock frequency required by the system. If different subsystems require clock signals of different frequencies, different phase-locked loops connected to the same crystal oscillator can be used to provide them.
