Abstract
A galvanic isolator having a transmitting section and a receiving section is disclosed. The transmitting section includes a frame input circuit, a data encoder, and a data transmitter. The frame input circuit receives an input data frame that includes a plurality of input binary bits. The data encoder encodes the input binary bits to generate an encoded data frame that includes a sequence of encoded binary bits in which two successive encoded binary bits represent each input binary bit. The successive encoded binary bits representing a 1 are 01 or 10, and the successive encoded binary bits representing a 0 are 00 or 11. The sequences are chosen to maximize the number of transitions in the encoded data frame. A data receiver recovers the encoded data frame by examining successive pairs of encoded data bits using a clock that is reset on the edges in the encoded data frame.
