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.

Claim (Index 19):
An electronic circuit, comprising:\n a plurality of clock lines to transfer a plurality of clock signals based on different delays respectively; and a clock recovery circuit to adjust skew between the plurality of clock signals based on a result of a comparison of a plurality of detection reference levels with a plurality of signal levels of data respectively, the plurality of detection reference levels being different from a transition reference level corresponding to detection of a transition of data, the plurality of signal levels of the data at a plurality of successive timings of the plurality of clock signals, wherein: adjusting the skew is based on signs of errors of the plurality of signal levels with respect to the plurality of detection reference levels being different from each other, and directions in which at least two of the different delays are adjusted to adjust the skew are different from each other.
