520T25DA20M0000 application field and working principle

520T25DA20M0000 is an oscillator based on digital phase locked loop (DPLL) technique. It is one of the most popular commercial oscillator solutions available. It is widely used in a variety of applications such as mobile communication, digital TV, satellite TV and computer peripherals systems. Its main application fields include frequency synthesis, radar systems, automatic line control, data acquisition, digital transmitters, etc.

The 520T25DA20M0000 oscillator consists of a phase detector, a loop filter, an adjustable voltage control oscillator (VCO), a divider circuit and a reference frequency oscillator. The phase detector is used to compare the phase of the reference frequency to the divided phase of the output of VCO to generate an error signal. The error signal is then filtered by the loop filter and the filtered output is used to adjust the control voltage of the VCO. When the filtered output is equal to the reference frequency, the phase is locked. The frequency of the output is adjustable through the control voltage.
