EMI-suppression plate for use in IEEE-1394 applications

摘要

An EMI suppression plate surrounds a galvanically isolated connector at the opening in a chassis that is provided for the connector. The plate is configured to provide an immediate high frequency coupling to the chassis ground. The plate comprises a circuit board that includes two conductors that are coupled by one or more capacitors. One conductor is in contact with an outer shell of the connector, and the other conductor is in contact with the chassis ground. By providing a high frequency coupling between the connector and chassis at the location of the connector opening on the chassis, the ground current path between the connector and chassis ground is minimized.
