Abstract

A connector with a port is provided that includes a first and second terminal, the first and second terminal configured to function as a differential pair and receive a differential signal. The differential pair is coupled a conditioning module. The conditioning module can be configured to provide an improved transformer. A common-mode circuit can be used to determine a level of common mode energy on the differential pair so as to provide feedback to an associated ASIC.

Claims

1. A connector, comprising:

a housing, the housing including a port configured to receive a plug connector;

a first and second terminal positioned in the port;

a first and second pin electrically coupled, respectively, to the first and second terminal;

a third and fourth pin;

a conditioning module including a transformer and a choke, the conditioning module having a first and second conductive member coupled to the first pin and second pin and a third and fourth conductive member coupled to the third and fourth pin, the first and third conductive member coupled together to form a first wiring pair and the second and fourth conductive member coupled together to form a second wiring pair, the first and second wiring pair being separately wound through a transformer, the first and second conductive member being wound through the choke.

2. The connector of claim 1, wherein the first and second conductive member are each formed with two wires.

3. The connector of claim 2, wherein the wires are 40 gauge wires.

4. The connector of claim 1, wherein the transformer is a first transformer and the conditioning module includes a second transducer, the second transducer configured to provide common mode energy sensing.

5. The connector of claim 4, wherein the second transformer is coupled to a centertap of the first transformer.

6. The connector of claim 5, wherein the second transformer is coupled to two conductive members and a second choke is provided between the second transformer and the two conductive members.

7. The connector of claim 4, wherein the second transformer is connected line side of the choke and is separated from the first and second conductive by two resistive elements.

8. The connector of claim 7, wherein the second transformer is coupled to two conductive members and a second choke is provided between the second transformer and the two conductive members.

9. The connector of claim 4, wherein the choke is positioned on a chip side of the first transformer and the second transformer is coupled to a centertap of the first transformer.

10. The connector of claim 9, wherein the second transformer is coupled to two conductive members and a second choke is provided between the second transformer and the two conductive members.
