Abstract:
A transmission line interface circuit includes a voltage regulator to control a voltage swing of the transmission line interface circuit for signal transmission. The transmission line interface circuit includes complementary driver elements, including a p-type driver element to pull up the transmission line in response to a logic high, and an n-type driver element to pull down the transmission line in response to a logic low. The voltage regulator is coupled between one of the driver elements and a respective voltage reference to reduce a voltage swing of the transmission line interface circuit.
