Abstract:
1. An apparatus comprising: a transformer block having output and input ports to communicate a plurality of data signals and a synchronous clock signal between a first device with a first voltage ground reference and a second device with a second voltage ground reference over a data communication link, where the first device to send the plurality of data signals to one or more input ports of a modulator block having one or more Boolean logic gates to receive each data signal in combination with the synchronous clock signal and one or more output ports of the modulator block to send a plurality of modulated data signals corresponding to the plurality of data signals to the input ports of the transformer block, and wherein one or more of the output ports of the transformer block to send the plurality of modulated data signals and the synchronous clock signal to the second device to provide the data communication link between devices having different voltage ground references, wherein the transformer block has a first output coupled to a resistive divider and a second output coupled to a receiving device with single ended logic.
