More Information
Summary:Disclosed is a network interface circuit, which comprises a first transmission channel and a second transmission channel, and the two channels respectively include an isolating transformer and a common-mode choke coil, and the common-mode choke coils of the two channels are jointly wound on a magnetic core. An electric connector applying the network interface circuit comprises an insulating body, a conductive terminal arranged on the insulating body and a signal processing module which is in electrical connection with the conductive terminal, and the module includes the interface circuit. The interface circuit and the electric connector applying the interface circuit can reduce the usage amount of magnetic cores and workload of manual winding when in manufacturing, thereby enhancing the production efficiency and reducing the product cost.
