Abstract: System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within electronic equipment. Transmission lines are selectively terminated in an N-phase polarity encoded transmitter when the transmission lines would otherwise be undriven. Data is mapped to a sequence of symbols to be transmitted on a plurality of wires. The sequence of symbols is encoded in three signals. A first terminal of a plurality of terminals may be driven such that transistors are activated to couple the first terminal to first and second voltage levels. The first terminal may further be driven such that a dedicated transistor is activated to couple the first terminal to an intermediate voltage level.
