Abstract
A prescaler ( ) includes a first frequency divider ( ) configured to receive an input signal at an input frequency. The prescaler further includes a phase rotator ( ) coupled to the first frequency divider to produce a plurality of signal phases in response to the input signal. A frequency control circuit ( ) is configured as a one-hot decoder to select one signal phase of the plurality of signal phases. The one-hot decoder provides maximum speed of operation of the prescaler by eliminating decoding of the feedback signal.
