A bi-directional isolation scheme is described in which digital data, including clock information, may be communicated bi-directionally across a single isolation barrier (16) without requiring a phase locked loop (PLL) based clock recovery procedure. In this way, the lead-time needed by the receiving circuit to recover the data clock signal may be reduced and the polarity (or 180° phase) ambiguities often associated with PLL-based methods may be avoided.
