Abstract
Improved coupler for Ethernet over twisted pair. An improved coupler has a first common mode choke for connecting an Ethernet PHY to the primary winding of a transformer. The secondary winding of the transformer connects through a second common mode choke for connection to a twisted pair line. In one embodiment, the first common mode choke, transformer, and second common mode choke are placed in the same package. In a second environment, a plurality of choke-transformer-choke units are placed in the same package. In a third embodiment, the plurality of choke-transformer-choke units may be integrated into a connector. Pairs of the second common mode chokes may share cores.
