The invention relates to electronic devices for generating synchronization signals, in particular to ultrahigh resolution synchronization signals whose temporal accuracy is less than a nanosecond. The inventive device operates not only with an internal clock but also with the external clock of a synchronizable device, thereby avoiding any temporal drift and uncertainty of the synchronization signals. The main element of the device is embodied in the form of a programmable digital component which operates with the external clock frequency and comprises programmable delay lines enabling to attain ultrahigh temporal resolutions. Said invention also relates to a system comprising several synchronization devices which are interconnected in such a way that the synchronization of different devices remains perfect. The invention makes it possible to control with high accuracy a quasi-unlimited number of devices. |
