<p>A circuit can include multiple data input ports and data output ports, pickoff tees coupled therebetween, and a resistive network coupled between the pickoff tees. A differential signal generator can be coupled with the resistive network and the pickoff tees. Resistances of the pickoff tees and resistive network can be selected such that impedances looking into the data input ports and data output ports are matched to a desired system impedance.
