1. A transmitter comprising:
- an output terminal;
a driver circuit configured to perform transition of a voltage of the output terminal among a plurality of voltages including a first voltage, a second voltage, and a third voltage between the first voltage and the second voltage; and
a control circuit configured to control the driver circuit to cause a transition start timing in a voltage transition of the voltage of the output terminal from the third voltage to the first voltage or the second voltage to be later than a transition start timing in a voltage transition of the voltage of the output terminal between the first voltage and the second voltage, and wherein the control circuit is configured to control the driver circuit to cause the transition start timing in the voltage transition from the third voltage to the first voltage or the second voltage to substantially match a cross timing in the voltage transition between the first voltage and the second voltage.

Abstract
A transmitter of the present disclosure includes: an output terminal; a driver that performs transition of a voltage of the output terminal among a plurality of voltages; and a controller that controls the driver to cause transition start timing in one voltage transition in voltage transition among the plurality of voltages to be later than transition start timing in another voltage transition.
