A Phase Locked Loop (1) comprising a frequency detector (10) including a balanced quadricorrelator (2), the loop (1) being characterized in that the quadricorrelator (2) comprises double edge clocked bi-stable circuits (21, 22, 23, 24, 25, 26, 27, 28) coupled to multiplexers (31, 32, 33, 34) being controlled by a signal having the same bitrate as the incoming D signal (D).
