The invention discloses a high precision output single-chip microcomputer phase-locked loop rapid frequency source. The high precision output single-chip microcomputer phase-locked loop rapid frequency source is characterized by comprising a switch power source which is fixedly mounted on a phase-locked loop and a single-chip microcomputer and is used for supplying power for the phase-locked loop and the single-chip microcomputer, wherein the phase-locked loop and the single-chip microcomputer are substantially connected, the phase-locked loop comprises a phase discriminator, a loop filter, a voltage control oscillator VCO and an N frequency divider which are sequentially connected to form a loop. Precise output of radiofrequency signals is realized through the rapid frequency source controlled by the phase-locked loop, feedback signals are reliably transmitted through three buses, intelligent frequency locking for maintenance work is realized, and online work, high output frequency, good inhibition performance and good product stability are all realized.
