Abstract

Timing test circuits, including programmable strobe and clock generators, may include at least two DLLs having differing numbers of delay elements thereby producing many timing signals having various phase relationships. A detector circuit can generate many different timing intervals as may be defined by independently selected events in signals arising from both of the DLLs.
