Abstract:
1. A signal receiving apparatus, comprising: an equalization module, configured to receive an input signal and to perform an equalization process on the input signal according to an equalization strength to generate an equalized signal; a coarse tuning module, coupled to the equalization module, configured to adjust the equalization strength according to the equalized signal until the equalized signal satisfies a preliminary convergence condition; a fine tuning module, coupled to the equalization module, configured to adjust the equalization strength according to the equalized signal when the equalized signal satisfies the preliminary convergence condition until the equalization strength satisfies a final convergence condition; a local oscillation source, configured to provide a local oscillation signal; and a clock signal generation module, configured to receive an original signal and to perform a clock signal recovery process on the original signal to generate a clock signal; wherein the clock signal generation module is configured as a frequency synthesizer to generate a substitute clock signal according to the local oscillation signal, if the clock signal remains in an unlocked status after a period of time.
