1. A controllable delay element, comprising:

  • a delay element to provide a variable delay to an input signal to generate an output signal, the variable delay to be controlled by a digital delay input, the delay element to have a delay range of the variable delay between a first delay to be set by a first value of the digital delay input and a second delay to be set by a second value of the digital delay input, the first delay and the second delay to be referenced to a same edge of the output signal; and

    ,a delay range control circuit to control the delay range in response to a delay range input.
