Abstract: A system may include a plurality of isolators to transfer data signals across an isolation barrier, one of the signals including a clock signal. A delay circuit may be included to receive the clock signal and provide a delayed clock signal that lags the clock signal by an amount representing a delay across the isolation barrier. The delayed clock signal may be delayed by a round trip propagation delay over the isolation barrier. The delayed clock signal may be used as a reference to read data sent over the isolation barrier.

Abstract: A multi-channel isolation system has N+1 isolators for N channels of communication data. N of the isolators may transfer data signals across an isolation barrier, one for each of the N channels of data. An N+1st isolator transfers refresh signals representing state of the data signals on the N isolators. Receiver circuitry, therefore, may receive signals from the N isolation channels without risk for collision with refresh signals. If reception of the refresh signals becomes necessary, circuitry on a receive side of the isolator may switch over to the N+1st receive path to output state data contained in the refresh signals.
