Abstract
Programmable logic device circuitry for receiving and/or transmitting a differential signal includes controllable invert circuitry that effectively reverses the polarity of the differential signal. The controllable invert circuitry operates on a single-ended (non-differential) signal that has either been derived from a differential input signal or from which a differential output signal will be derived.
