1. A bi-directional isolation system for providing an isolated communication channel for a source data signal synchronized by a source clock signal, comprising:

  • a bi-directional isolation barrier;

    a source interface circuit coupled on one side of the isolation barrier and configured to multiplex the source clock signal on the source data signal and to transmit the multiplex signal across the isolation barrier; and

    an isolated interface circuit coupled on an opposite side of the isolation barrier and configured to generate from the multiplex signal a recovered data signal and a recovered clock signal synchronized with the source clock signal.
