Abstract
A semiconductor integrated circuit includes a converter converting an analog signal into a digital signal based on a clock signal; a comparator determining values of data based on the digital signal; a recovery circuit recovering the clock signal based on the digital signal and the data; and a control circuit. The recovery circuit includes a phase detector calculating a sum of a first value and offset, the first value being a value based on the digital signal and the data and relating to a phase of the clock signal; and a loop filter calculating a correction amount of the phase of the clock signal based on the sum. The control circuit is configured to gradually change the offset from a second value to zero after the second value is added as the offset.
