The present invention discloses a clock generator circuit for generating an output clock signal. The clock generator circuit includes: a random frequency code generator for generating a frequency code randomly, wherein the random frequency code generator is clocked by a first clock signal; an accumulator electrically connected to the random frequency code generator, for generating a selection code by accumulating the frequency code, wherein the accumulator is clocked by the first clock signal; a first multiplexer electrically connected to the accumulator, for selecting one of a plurality of reference clock signals as the first clock signal according to the selection code; and a toggle circuit electrically connected to the first multiplexer, being clocked by the first clock signal for generating the output clock signal.
