ABSTRACT:
A programmable delay line includes a first oscillator that is enabled and generates a plurality of clock cycles of a clock signal in response to a transition of the input signal. A first programmable ripple counter is coupled to the first oscillator, counts with each successive clock cycle to a programmed count, and generates a first signal in response to reaching the programmed count. A control circuit is coupled to the first oscillator and to the first programmable ripple counter. The control circuit transitions the output signal and disables the first oscillator in response to the first signal.
