ABSTRACT:
A system is provided for transferring information across a conductor 203. Transmitting circuitry 210 receives information in the form of a first signal having a first voltage swing and, in response, outputs a second signal having a second voltage swing. The first voltage swing is between a first high voltage and a first low voltage and the second voltage swing is between a second high voltage less than the first high voltage and a second low voltage greater than the first low voltage. The second high voltage is substantially equal to a voltage level of a first voltage rail to which the transmitting circuitry 210 is coupled and the second low voltage is substantially equal to a voltage level of a second voltage rail to which the transmitting circuitry 210 is coupled. The conductor 203 carries the second signal output from the transmitting circuitry 210. Receiving circuitry 212 receives the second signal output from the transmitting circuitry 210 via the conductor 203 and, in response, outputs a signal having the first voltage swing.
