A signal receiving circuit includes: a sampler, for receiving an analog signal and sampling the analog signal according to a sampling clock to generate a sampling signal; an ADC, coupled to the sampler, for converting the sampling signal to a digital signal; an equalizer, coupled to the ADC, for equalizing the digital signal to generate an equalized digital signal; a quantizer, coupled to the equalizer for quantizing the equalized digital signal to generate a processed digital signal; and a timing recovery circuit, directly connected to the output terminal of the sampler and coupled to the quantizer, for adjusting the timing of the sampling clock according to the processed digital signal and the digital signal. Timing recovery parameter generating circuits are also disclosed.
