PLL using unbalanced quadricorrelator
摘要:
A Phase Locked Loop (1) used in a data and clock recovery comprising a frequency detector (10) including a quadricorrelator (2), the quadricorrelator (2) comprising a frequency detector including double edge clocked bi-stable circuits (21, 22, 23, 24) coupled to a first multiplexer (31) and to a second multiplexer (32) being controlled by a signal having a same bitrate as the incoming signal (D), and a phase detector (DFF) controlled by a first signal pair (PQ, PQ provided by the first multiplexer (31) and by a second signal pair (PI, PI) provided by the second multiplexer (32).
