A circuit for delaying an input control signal, comprises a clock circuit to generate a clock signal having a frequency different from an input clock signal to delay and including a clock signal input, a derivative clock signal output, an input to program a frequency ratio between its input clock frequency and its output clock frequency. A clock capturing circuit provides a determined number of delay elements required to provide a delay of an amount of the period of the signal provided by the clock circuit. A delay calculation circuit receives the determined number of delay elements and calculates a number of delay elements needed to delay the input control signal by an amount of time. A delay circuit includes a control signal input, a select input for receiving the number of delay elements provided by the delay calculation circuit.
