摘要
Systems, methods and apparatus are described for use in a communications link having a number of connectors. A method for communication using differential signaling with symbol transition clocking signaling communicates symbols over a communications link without transmitting a clock signal in a dedicated lane of the communications link. At a receiver, clock information may be extracted without using a phase-locked loop. The method includes converting data bits into a plurality of transition numbers, converting the plurality of transition numbers into a sequence of symbols, and transmitting the sequence of symbols over a plurality of signal wires. A clock signal may be embedded in transitions between consecutive symbols in the sequence of symbols. Each consecutive pair of transition numbers in the plurality of transition numbers may include two transition numbers that are different from one another. The sequence of symbols may be transmitted as a plurality of differential signals.
