    Abstract: Techniques for duplex communication and power transfer across an isolator are provided. In an example, a first transceiver coupled to a first side of an isolator can include a transmit modulator configured to receive first data and timing signals, to provide control signals to oscillate an output of the transceiver to transmit power and to order each half-cycle of an oscillation cycle of the output to transmit the first data. A second transceiver coupled to a second side of the isolator can include a receive detection circuit configured to compare a received oscillation cycle with a plurality of thresholds and to provide a plurality of comparator outputs indicative of reception of the positive half-cycle and the negative half-cycle, and a receive decoder configured to identify the order of half-cycles and to provide an output indicative of logic level of the first data.

    Abstract: An apparatus is provided comprising: a first power domain that includes a first component that operates at a first voltage level; a second power domain that includes a media access controller (MAC) that operates at a second voltage level; and a third power domain that includes a physical media access (PHY) device that operates at a third voltage level; wherein the first voltage level is higher than the second voltage level; and wherein the second voltage level is unreferenced; further including: a first reinforced electrical isolation circuit disposed on a first circuit path that includes at least one signal lane that extends between the first power domain and the second power domain; and a second reinforced electrical isolation circuit disposed on a second circuit path that includes at least one signal lane that extends between the MAC device and the PHY device.

    Abstract: An Ethernet or other communications module can amplify and reinforce a signal received from a non-local source without requiring a transformer or other magnetic component. A semiconductor integrated difference amplifier circuit can be used to amplify and reinforce a differential mode component of the received signal, while also attenuating a common mode component of the received signal. A transmission compensation network can generate a phase-shifted version of a locally transmitted signal being placed on the same communication terminals as the received signal during full duplex communications, for cancellation of such locally transmitted signal at inputs of a local receiver circuit. This can enhance detection of the received signal generated by the non-local source.
