1. A data transmission system, comprising:
a first circuit comprising a transmitter powered by a first power supply voltage with respect to ground and having an input for receiving a data output signal, and an output;
a second circuit comprising a receiver powered by a second power supply voltage with respect to ground and having a first input coupled to said output of said transmitter, a second input for receiving a reference voltage, and an output for providing a data input signal; and
a reference voltage generation circuit forming said reference voltage by mixing a first signal generated by said first circuit based on said first power supply voltage and a second signal generated by said second circuit based on said second power supply voltage.
