Implementation of PLL frequency synthesizer and its applicatio

  • The paper described composition model and working principle of PLL frequency synthesizer, and proposed method of automatic channel selection achieved by MCU control combined with its application in intermediate frequency wireless communication system in mine. The application of PLL frequency synthesizer allows wireless terminal to switch quickly in different base stations, and has advantages of high frequency resolution, short frequency conversion time, continuous phase during signal conversion and so on.
