摘要： A connector system for transferring electricity and data. The connector system includes a receptacle and a plug. The receptacle includes a shield, a power contact, a ground contact, and a data contact. The shield includes power apertures through which power conductor segments of the power contact extend, ground apertures through which ground conductor segments of the ground contact extend, and a data aperture through which a shield member and a data conductor of the data contact extend. The plug includes another power contact connected to a power wire, another ground contact connected to a ground wire, and another data contact. The plug is receivable by the receptacle to electrically connect the power wire conductor to the power conductor segments of the receptacle, to electrically connect the ground wire conductor to the ground conductor segments of the receptacle, and to electrically connect the data contact to the other data contact, respectively.

摘要： Embodiments allow for the use of the SS modulation technique (and thus for significant reduction of EMI due to clock transmission) in scenarios involving tight synchronization requirements between two devices. In particular, embodiments can be used in high-speed communication networks (e.g., high-speed Ethernet) where a clock signal embedded in the data stream at the transmitter and recovered from the data stream at the receiver is the only source for synchronization between the transmitter and the receiver (i.e., no other synchronization channel available). Embodiments are also especially useful in communication systems utilizing echo cancellers.

摘要： According to one exemplary embodiment, a connector for coupling a communications medium to an electronic device includes a common-mode suppression block coupled to a number of connector pins. The common-mode suppression block is configured to reduce common-mode noise coupling between the communications medium and the connector pins in the connector. The common-mode suppression block is further configured to provide substantially no attenuation to a differential-mode signal. In one embodiment, the communications medium is an Ethernet cable and the connector is an Ethernet plug. In one embodiment, the common-mode suppression block comprises common-mode chokes. In one embodiment, the connector is an RJ45 plug.

摘要： Disclosed is a communications interface to connect to a first device and to establish a communication between the first device and a second device over a medium. The communications interface comprises at least one common mode choke having a first end configured to connect to an Ethernet transceiver of the first device. The communications interface further comprises an optional capacitor having a first end coupled to a second end of the at least one common mode choke and having a second end configured to connect to the medium. The communications interface does not include any transformers connected to the second end of the at least one common mode choke. The Ethernet communications is readily adaptable to differential-pair cabling and applications in harsh electromagnetic interference environments, such as automotive, aero-space, air crafts, water crafts, trains, railroad and marine applications, where high rejection of EMI is required.

摘要： A method and system for detecting transformer saturation in a communication interface is provided. The method may include detecting a change in impedance resulting from transformer saturation of at least one isolation transformer utilized in a network path of a network. The network may conform to an IEEE 802.3af specification where power may be delivered through the network. The method may further comprise generating a pulse at a one end of the network and measuring a reflection at that end to detect the transformer saturation. In response to the impedance change, a transmitter signal may be pre-distorted in order to compensate for the detected transformer saturation, or the power delivered over the network may be disabled.
