| Abstract: | This paper introduced the design and realization of a renewable frequency synthesizer on- line controlled by a EZ- USB in- terface chip with enhanced 51 core. The article mainly introduces the design of the frequency Synthesizer, the hardware and the software.The output of the frequency synthesizer can range from zero to 100MHz precisely, and the precision can be up toHz, the module have been used in several receiver of BB successfully. |
