Abstract

See full text

In an integrated-circuit component having a signal transmitter receives a transmitter power supply that cycles periodically between power-off and power-on voltage levels to define a sequence of enable intervals during which the signal transmitter is to output voltage levels corresponding to respective transmit data bits onto an external signaling link. The signal transmitter generates, at the start of each output-enable interval, an initial nonzero voltage having a first polarity across conductors of the external signaling link, and then conditionally transitions the initial nonzero voltage to a second nonzero voltage according to whether the transmit data bit corresponding to the output-enable interval has a predetermined one of two binary states, the second nonzero voltage having a polarity opposite the first polarity.
