Systems for bi-directional single-ended transmission are described. For example, a system may include a receiver with a first differential input terminal and a second differential input terminal, wherein the first differential input terminal is coupled to a first node and the second differential input terminal is coupled to a second node; a transmitter with an output terminal coupled to a third node; a first inductor connected between the first node and the third node; a second inductor connected between the second node and the third node; and a shunt resistor connected between the third node and a ground node.

Bi-directional single-ended transmission systems

Systems for bi-directional single-ended transmission are described. For example, a system may include a receiver with a first differential input terminal and a second differential input terminal, wherein the first differential input terminal is coupled to a first node and the second differential input terminal is coupled to a second node; a transmitter with an output terminal coupled to a third node; a first inductor connected between the first node and the third node; a second inductor connected between the second node and the third node; and a shunt resistor connected between the third node and a ground node. Some implementations include a first inductor with an inductance within twenty percent of 1 microhenry and a capacitance less than a tenth of a picofarad is included in a filter coupling a power supply to transmission line. The first inductor may connect to the transmission line.
