Abstract
A controllable delay element includes a delay element to provide a variable delay from an input signal to an output signal. The variable delay can be controlled by a digital delay input. The delay element has a delay range that is controlled in response to a delay range input. The delay range of the delay element can be calibrated to a desired range of delays in response to a relative delay between a first timing reference and a second timing reference. A common timing reference is applied to a plurality of receivers and a strobe receiver. The delay through the strobe receiver is adjusted to measure the delay mismatches between the plurality of receivers. The mismatches are used to select a value for the delay through the strobe receiver.
