Abstract: PROBLEM TO BE SOLVED: To provide a device for generating synchronous numeric signals, and to provide its method. SOLUTION: The device includes a reference generating devices (4, 21) supplying a reference signal (SCONTR) and a first timing signal (T1), both having a reference frequency (F1); and a timed (that is, synchronized) generating devices (30, 31, 35) supplying a synchronized signal (SACC) having the reference frequency (F1). The device further includes a synchronization stage generating a second timing signal (T2) having a first controlled frequency (F2) correlated to the reference frequency (F1), and phase synchronization pulses (TDEC) having a preset delay (K) programmable with respect to the first timing signal (T1) and the first frequency (F1).
