ABSTRACT:
A programmable divider apparatus comprises a first divider, a second divider, a feedback control unit, and a plurality of control signals. The first divider provides a frequency division operation of division by at least three integers, the second divider is cascaded to the first divider to provide a frequency division operation of division by two integers. The feedback control unit is coupled to between the first divider and the second divider to provide a feedback control signal to selectively supply an output of the second divider to an input of the first divider. The apparatus control signals and the feedback control signal are used to execute the first divider or the second divider.
