  • Publication number: 20230238942
    Abstract: A differential signal represented by a voltage difference between two signals that propagate through two signal lines is input to a signal processing circuit from a connector. A first suppressing circuit and a second suppressing circuit suppress peak values of the two signals. A DC removing circuit removes DC components of the two signals. A common mode choke coil (noise removing circuit) removes common mode noise included in the two signals. The DC removing circuit and the noise removing circuit are disposed between the first suppressing circuit and the second suppressing circuits. If the voltage of the signal line is a first threshold voltage, a current flows through a first suppressing device (first connection device). If the voltage of the signal line is a second threshold voltage, a current flows through a second suppressing device (second connection device). The second threshold voltage is less than the first threshold voltage.
