Abstract
A frequency divider includes an output-and-control-signals generation circuit. The output-and-control-signals generation circuit outputs an output clock signal and a control signal responsive to an input clock signal and a state signal. A shift register, characterized by having a count-sequence length of 2 −1, outputs the state signal responsive to the output clock signal. A feedback loop is associated with the shift register. An exclusive or (XOR) gate, a multiplexer, and a plurality of flip-flops are disposed within the feedback loop. The multiplexer has a first input and a second input. A parallel-to-serial-input generation circuit is coupled to the output- and control-signals generation circuit and to the shift register, and receives the control signal. The first input of the multiplexer is coupled to the shift register and the second input of the multiplexer is coupled to the parallel-to-serial-input generation circuit.
