ABSTRACT:
The present inventions provide a high-speed serial data cable assembly with improved electromagnetic performance. In one embodiment, the high-speed serial data cable assembly includes a first connector, a second connector, a cable portion, and a capacitor. The first connector includes a conductive housing and a first plurality of pins, one of the first plurality of the pins being a ground pin. The second connector includes a conductive housing and a second plurality of pins. The cable portion includes a shield, the cable portion electrically coupling the first plurality of pins to the second plurality of pins, and the shield electrically coupling the ground pin of the first connector to the conductive housing of the second connector. The capacitor electrically couples the conductive housing of the first connector to the shield, wherein the capacitor allows a current to flow from the shield to the conductive housing of the first connector when data is being transmitted through the cable portion at frequencies corresponding to the capacitor. In another embodiment of the present invention, the high-speed serial data cable assembly also includes a toroid disposed around the cable portion, such that the electromagnetic emissions of the high-speed serial data cable assembly is further reduced during the transmission of data. A method of manufacturing a high-speed serial data cable assembly with improved electromagnetic performance is further disclosed.
