Frequency-locked loops (FLLs) are indispensable for modern power system synchronization, providing direct estimation of grid frequency and phase in grid-connected converters. Unlike phase-locked loops ...

This application note discusses phase frequency detector characteristics that affect phase-locked loop (PLL) dead band and jitter performance. In PLLs that employ charge pump loop filter designs the ...

The circuit shown in Figure 1 is a high performance phase locked loop (PLL) that uses high speed clock buffers and low noise LDOs to maintain low phase noise even at low reference and RF frequencies.

But taking a voltage-controlled oscillator at 100 MHz (nominal) and dividing its output by 100 will give you a signal you can lock to a 1 MHz crystal oscillator which is, of course, trivial to build.

When Hackaday runs a contest, we see all manner of clever projects. But inevitably there are some we don’t see, because their builders didn’t manage to get them finished in time. [Park Frazer]’s phase ...
