A receiving circuit includes: an interpolation circuit that generates, by using an interpolation coefficient, output data including a data point and a boundary point from pieces of input data that are input in chronological order; a detection circuit that outputs a detection signal when the detection circuit detects a phase of the output data by using the boundary point of the output data; a low pass filter that filters the detection signal and generates the interpolation coefficient; and a modulation circuit that modulates, by using a modulation signal having a frequency different from a cutoff frequency of the low pass filter, the interpolation coefficient generated by the low pass filter, and outputs the modulated interpolation coefficient to the interpolation circuit.
