Various types of high-speed digital galvanic isolators and corresponding integrated low voltage differential signal (“LVDS”) interfaces are disclosed herein. According to some embodiments, phantom power is provided to one side of a galvanic isolator from the other side of the isolator via a twisted pair cable with shielding interconnecting the two sides, and therefore eliminate the need to provide power to both sides of the galvanic isolator through different power supplies or by way of separate physical wiring being routed and connected to the two opposing sides of the isolator. Such phantom power supply configurations reduce cost, lower power consumption, and increase the number of engineering design options available in a device where high speed serial data communication with low noise are required. |
