synchronizers

Synchronizers are devices, circuits, or procedures that align the timing of events in a system to prevent errors during transitions. They are used wherever asynchronous events must be coordinated with a synchronous system or with moving parts to avoid mistiming and data loss.

In mechanical engineering, particularly in automotive engineering, a synchronizer or synchromesh is a gear-shift element that

In digital electronics, a synchronizer transfers a signal from an asynchronous source into a synchronous clock

In timekeeping and networking, synchronizers refer to methods and protocols that keep clocks aligned across devices

Overall, synchronizers address the need for reliable timing alignment across mechanical, electrical, and temporal domains, with
