Abstract
A transmitter circuit receives a PWM input signal and a clock signal. A logic circuit generates a control signal as a function of the clock signal. The control signal is normally set to high, and is periodically set to low for a transmission time interval when an edge is detected in the clock signal. The transmission time interval is shorter than a half clock period of the clock signal. A tri-state transmitter receives the PWM input signal and the control signal, and produces first and a second output signals at first and second transmitter output nodes, respectively. The output signals have a voltage swing between a positive voltage and a reference voltage. An output control circuit is sensitive to the control signal and is coupled to the first and second transmitter output nodes.
