Abstract
A receiving device includes first, second, and third circuits, and a processing circuit. The first circuit is configured to calculate a phase difference between a first clock signal and a data signal, which is a signal modulated by pulse-amplitude modulation. The second circuit is configured to generate a second clock signal based on the first clock signal and the phase difference. Jitter is added to second clock signal. The third circuit is configured to demodulate the data signal by comparing an amplitude of each pulse of the data signal with a threshold value at a timing synchronized to the second clock signal added the jitter. The processing circuit is configured to count the number of errors in the demodulated data signal and then calibrate the threshold value based on the counted number of errors.
