Data isolators for providing isolation between two ports that enable dynamic communication are described. The dynamic communication may be achieved by varying a ratio of the data rate relative to a clock frequency of a clock signal. The data isolator may include a first circuit that transmits data across an isolation barrier when the clock signal is in a first state and a second circuit that transmits data across the isolation barrier when the clock signal is in a second state. The clock frequency may be variable and, as a result, change the duration of data transmissions in a given clock cycle. For example, the clock frequency may be reduced to increase the number of bits transmitted per clock cycle and, conversely, increased to reduce the number of bits transmitted per clock cycle. Thus, the number of bits transmitted per clock cycle may be adjusted to suit the situation.
