摘要： A receiver circuit for receiving data is described. The receiver circuit comprises a phase detector configured to receive an input data signal; a frequency path circuit configured to receive an output of the phase detector; and a false lock detection circuit configured to receive the output of the phase detector and an output of the frequency path circuit; wherein the false lock detection circuit detects a false lock of the receiver circuit to the input data signal based upon an output of the phase detector and provides a frequency offset to the frequency path circuit. A method of receiving data is also described.
