Working principle: When ASFL1-7.3728MHZ-EC-T oscillator is used for frequency synthesis, an internal reference frequency is firstly generated. Then the frequency is passed to the phase detector and then to the loop filter. The filter will pass the output signal to the VCO and regulate the VCO output to the required frequency. For example, when the user sets the frequency to 27MHz, the VCO output will be tuned to 27MHz after adjusting the filter. After the tuning process, the reference frequency and the VCO output are compared, and if the output does not match the reference frequency, the phase detector will produce an error signal to the loop filter to tune the VCO output.

The frequency of ASFL1-7.3728MHZ-EC-T oscillator is determined by the capacitance of the crystal it contains. The capacitance of the crystal is fixed, hence it directly influences the oscillator frequency. As the capacitance increases, the frequency of the oscillator decreases.
