Abstract
A ringing suppression circuit includes: a single line switching element, which is driven by a voltage, that is connected between a pair of signal lines; a controller that detects a change in a level of the differential signal and turns on the single line switching element to lower an impedance between the pair of signal lines; a period detector that detects a length of a suppressing period indicated by a setting signal, which is an input; and a suppressing period storage that stores the length of the suppressing period which is detected by the period detector. In addition, the pair of signal lines includes a high potential signal line and a low potential signal line. Moreover, the controller turns on the single line switching element for only the suppressing period having the length, which is stored in the suppressing period storage.
