Abstract
An electronic circuit card comprises a printed circuit board with electronic components. The electronic components comprise drivers for transmitting transmit (TX) signals and receivers for receiving receive (RX) signals, according to several groups of interface signals. There is further provided a connector edge, arranged at an edge of the card, and configured to allow the card to be connected to an external connector. This connector edge comprises two subsets of symmetric pins on respective (opposite) sides thereof. The drivers and the receivers are connected to the pins, for respectively conveying the TX signals and the RX signals. Pins are assigned such that, for each of the several groups of supported interface signals, any pin (of any of the subsets) connected to transmit TX signals is located opposite a pin (of the other subset) connected to receive RX signals. Pairs of consecutive pins (on each side) typically come in differential pairs.
