Abstract
A circuit board and connector for use in an electrical connector has been provided. The circuit board comprises first and second signal contacts associated as a differential pair. A ground contact is located immediately adjacent the first signal contact and is joined directly to a ground plane provided within the circuit board. A floated contact is located immediately adjacent the second signal contact. A component interconnects the floated contact to the ground plane, forming an open circuit when a DC signal is impressed on the floated contact and a closed circuit when AC interference is impressed on the floated contact.
