Abstract: Methods, apparatus, and systems for data communication over a multi-wire, multi-phase interface are disclosed. A method includes equalizing three-phase signals received from two wires of the interface to provide equalized signals, providing first and second difference signals by comparing voltage differences between the equalized signals with first and second reference voltage levels respectively, capturing delayed and undelayed versions of the second difference signal using flipflops triggered by different edges in the first difference signal, and adjusting an equalizing circuit until outputs of the first flipflops indicate that a ratio of low-frequency attenuation to high-frequency amplification has been achieved that enables information to be accurately decoded from the three-phase signals. The three-phase signal received from a first of the two wires is in a different phase than the three-phase signal received from a second of the two wires.

Abstract: A method of MIMO signal transmission on a cable is disclosed. The cable includes at least a first inner conductor, a second inner conductor, and an outer conductive shield. A first data signal is transmitted using the conductive shield and the first inner conductor. A second data signal is transmitted using at least the second inner conductor. The first and second data signals may be transmitted concurrently. For some embodiments, the second data signal may be transmitted using the first and second inner conductors. Thus, the second data signal may be a differential signal. For other embodiments, the first data signal may be transmitted using the conductive shield and the first inner conductor, and the second data signal may be transmitted using the conductive shield and the second inner conductor.
