A second signal processor is provided in the subsequent stage of the first signal processor and performs predetermined signal processing on an output signal from the first signal processor to provide a change to a characteristic value thereof. An amount of change provided to the characteristic value of the signal by the second signal processor is dependent on a power supply voltage. An amount of change provided to the characteristic value of the signal by the first signal processor is configured to be adjustable. A control circuit monitors a power supply voltage supplied to the second signal processor and adjusts in accordance with the power supply voltage the amount of change provided to the characteristic value of the signal by the first signal processor.

摘要： A comparison judgment circuit judges the level of a signal received, via a transmission line, from a second device which is a communication partner. An input/output terminal is connected to the transmission line. An attenuator circuit attenuates the voltage at the input/output terminal so as to generate an attenuated voltage. A level comparator compares the attenuated voltage with a predetermined threshold voltage, and generates a level judgment signal that corresponds to the comparison result. A protection circuit monitors the voltage at the input/output terminal or the attenuated voltage. When the voltage to be monitored deviates from a predetermined voltage range, the protection circuit forcibly cuts off or changes the voltage input to the level comparator.

摘要： A first current source supplies a tail current It to a plurality of differential pairs. A pre-driver outputs gate signals to the gates of transistors of the corresponding differential pair. A pre-driver is configured to switch the state between the enable state and the disable state. In the enable state, the pre-driver outputs the gate signals that correspond to the differential signals. In the disable state, the pre-driver outputs the gate signals having levels which instruct the transistors of the corresponding differential pair to switch off.
