Abstract
Apparatus for communicating across an isolation barrier. In one embodiment, the apparatus comprises a transformer having a first winding disposed on a first side of a printed circuit board (PCB) and coupled to a first local ground, and a second winding disposed on a second side of the PCB, the second side opposite to the first side, and coupled to a second local ground; a transmitter coupled to the first winding; and a receiver, coupled the second winding, that generates an output signal based on a signal received from the transmitter.
