Conventional clock-fail detectors use silicon delay lines and flip-flops to detect stuck-at-high and stuck-at-low fault conditions in a clock source. Because commercial delay-line devices typically ...

PLL circuits that produce strobe signals synchronized to jittery data overcome the effects of jitter. Sophisticated techniques quantify the performance of these circuits and let you predict how well ...

Clock redundancy is required for many of today’s data-communication, networking, and computer systems. Any interruption due to component or board-level failure, or even simply regular system ...

This project from a few years back is an interesting take on a metal detector. Instead of building a detection circuit, [Bruno Gavand] replaced the external clock crystal with an inductor. Here you ...
