摘要：
A data lock detection system may include a receiver configured to receive a data signal, a phase detector configured to output a phase detection output signal representative of the data signal with respect to a clock signal, and a lock detector configured to receive the phase detection output signal. The lock detector is configured to determine a presence of a frequency difference between the data signal and the clock signal and output a lock determination output signal that indicates if the data signal is locked or unlocked with the clock signal.
