Abstract:
An embodiment is proposed for trimming a programmable delay line in an integrated device, which delay line is adapted to delay an input signal being synchronous with a synchronization signal of the integrated device—by a total delay. An embodiment of a corresponding method includes the steps of: preliminary programming the delay line to provide a selected nominal value of the total delay equal to a period of the timing signal, and trimming the delay line to vary an actual value of the total delay until the actual value of the total delay matches the period of the synchronization signal.
