Abstract
A timing lock identification method is provided according to an embodiment of the disclosure. The method includes: generating one or more first phase adjustment pulses and one or more second phase adjustment pulses by a timing recovery circuit, where the one or more first phase adjustment pulses are configured to increase a phase of an output signal of an oscillator, and the one or more second phase adjustment pulses are configured to decrease the phase of the output signal; and obtaining a difference value between the number of the one or more first phase adjustment pulses and the number of the one or more second phase adjustment pulses in a detection window and determining whether the timing recovery circuit reaches a locking state of timing recovery according to the difference value. Furthermore, a signal receiving circuit is provided according to an embodiment of the disclosure.
