Abstract
An isolator includes a transmitter, a coupling module and a receiver. The transmitter drives an input of the coupling module in response to a digital signal, such that in response to a first type of digital data value in the digital signal, a signal of a first predetermined type is supplied to the input and in response to a second type of digital data value in the digital signal, a signal of a second predetermined type is supplied to the input, the signals of the first type and the second type each including an initiation signal that announces a time window during which another portion of the signals representing a digital data value of the first type or the second type will be valid. The receiver is coupled to an output of the coupling module to receive and to decode signals in correspondence to the signals provided to the input.
