Abstract
An embodiment of a communication circuit for communicating data across an isolation barrier may include an input circuit to receive a plurality of input data channels, a framing circuit to frame an input data packet from the plurality of input data channels, an encoding circuit to select a characteristic of a data symbol to represent a plurality of bits of the framed input data packet, and a driver circuit to drive one or more data symbols representing the framed input data packet onto an isolator configured to communicate data across the isolation barrier. The encoding circuit may select an amplitude, frequency or phase of the data symbol from a plurality of predetermined amplitudes, frequencies or phases, to encode the plurality of bits as the selected amplitude, frequency or phase. The communication circuit also may include a receive circuit to receive one or more second data symbols from the isolator, a decoding circuit to decode a plurality of bits of an output data packet as a function of a characteristic of the second data symbol, and a deframing circuit to deframe the output data packet into output data of a plurality of output data channels.
