Abstract
Dynamic adjustment of offset between timebases of separated electronic circuits is provided based on an amount of time between synchronization events, wherein a synchronization event is an event involving communication across a separation between the separated electronic circuits in order to synchronize the timebases. The dynamic adjustment can be dynamically or adaptively adjusting a margin of error to account for drift that may have occurred since a prior synchronization event. Adjustments might be done by applying a learning sequence to quantify and adjust for static or slowly varying delays between the timebases and coordinating the timebases using output of the learning sequence. The learning sequence might quantify and adjust for static or slowly varying delays and frequency drift in a communication system having a master timebase device and slave timebase devices wherein slave timebase devices are configured to adjust their local timebases to coincide with the master timebase by obtaining timing/synchronization information during one or more events, the events being communication and/or synchronization events, analyzing the timing/synchronization information to derive timing…
