    Abstract: A signal receiving circuit may include a receiving equalizer and a sequence estimator. The receiving equalizer may be configured to compensate an inter-symbol interference in a signal from an external to output an equalization data, based on a receiving signal from an outside. The sequence estimator may be configured to determine a termination symbol, based on the equalization data, to perform a decoding on the receiving signal, based on the determined termination symbol, and to output the decoded receiving signal as a sequence data.

    Abstract: A data recovery circuit adjusts skew between a first and second clock signals when a signal level of recovered data changes relative to first reference level between a first timing of the first clock signal and a second timing of the second clock signal. Prior to adjusting the skew, a first signal level of the recovered data at the first timing is compared to a second and/or a third reference level. A second signal level at the second timing is compared to the second and/or the third reference level. The skew is adjusted based on a first sign of an error of the first signal level relative to one of the second and third reference levels. The first sign is opposite to a second sign of an error of the second signal level relative to another one of the second and third reference levels.
