Abstract
An apparatus includes a transmitter circuit coupled to a termination resistor. The transmitter circuit generates a number of link pulses. A driver circuit is coupled to the transmitter circuit to control a dynamic range of the link pulses. A transformer couples the termination resistor via a transmission medium to a far-end transceiver. The driver circuit controls the dynamic range of the link pulses by providing complementary digital input signals to the transmitter circuit, and the complementary digital input signals include ramp sections.
