Method for synchronizing digital data sent in series

A method for synchronizing digital data (D) sent in series by a transmitter (A) having a clock signal (h1) of frequency (freq1) to a receiver (B) having a clock signal (h2) of frequency (freq2), characterized in that it comprises the steps a) to d) iterated until a stoppage condition is met and a step e) carried out following the last iteration of step d), the steps a) to e) being the following:

• a) sending by the transmitter (A) a digital datum to the receiver (B);
• b) generating N channels, each of the channels containing the datum received by the receiver, and each ith channel being time shifted with respect to the (i−1)th channel, N being an integer greater than or equal to 3 and i being an integer between 2 and N;
• c) sampling the N channels at the frequency (freq2) of the clock (h2) of the receiver in order to generate digital data temporally aligned with the clock (h2);
• d) comparing the data of the N channels in groups of (2m+1) successive channels, m being greater than or equal to 1 and such that (2m+1) is less than or equal to N, and selecting groups of (2m+1) channels in which the (2m+1) successive channels contain identical data in each iteration;
• e) selecting one of the channels belonging to the group selected in the preceding step, the data contained in this channel being considered to be synchronized and in phase with the clock (h2) of the receiver and defining a variable (P) equal to the value (i) of the selected channel.
