ABSTRACT:
A frequency generator apparatus and a control circuit thereof are provided. The frequency generator apparatus comprises the control circuit and a frequency generator, wherein the control circuit contains an electric fuse (efuse). The control circuit outputs an enabling signal according to the state of the efuse. The frequency generator is coupled to the control circuit, receives the enabling signal, and decides to output a frequency signal or not according to the enabling signal.
