Abstract
The present disclosure discloses a signal receiving apparatus having parameter optimization mechanism. A signal processing circuit processes a data signal according to at least one equalization parameter to generate an equalized data signal. A clock data recovery circuit performs clock data recovery on the equalized data signal according to a primary sampling signal and a primary threshold value to generate primary recovered data. A multi-sampling circuit performs clock data recovery on the equalized data signal according to secondary sampling signals and secondary threshold values to generate a plurality of pieces of secondary recovered data. A parameter optimization circuit performs comparison and statistics on the primary recovered data and the secondary recovered data to generate an analysis result to control the signal processing circuit to adjust the equalization parameter according to the analysis result and a predetermined optimized parameter requirement such that the analysis result approximates the predetermined optimized parameter requirement.
