<p>An arrangement for transmission of information from a first electronic unit (1), transmitter, to a second electronic unit (2), receiver, on a balanced two-wire link (3, 4). In the arrangement the voltage difference between the two wires (3, 4) can assume three different values and each change between these values leads to a transmission of a binary symbol whose value is distinctly determined by the change. The information signal, which is transmitted via the two-wire link, is self-clocked which means that it contains both the data signal and the clock signal. Preferably, the transmitter (1) comprises one encoder for encoding the clock signal and data signal and the receiver (2) comprises two comparators, one clock extracting circuit and one decoder. Preferably, the arrangement can be used in communication e.g. between chips or in local networks.</p> |
