    摘要： A power line communication apparatus includes a first power line communication device disposed at a signal transmit end, a second power line communication device disposed at a signal receive end, a power line, a first magnetic ring disposed at the signal transmit end, and a second magnetic ring disposed at the signal receive end. The second power line communication device receives the modulated signal from the power line. The power line includes a wire for transmitting electric energy and a shield layer that wraps the wire for electromagnetic shielding. The wire and the shield layer separately extend from the signal transmit end to the signal receive end. The first magnetic ring and the second magnetic ring are separately coupled to the shield layer, to suppress inductance attenuation of the magnetic ring and improve reliability of the transmitted modulated signal.

    摘要： Apparatus and method for trapping RF on shields of a multiply shielded RF cable. In some embodiments, the RF trap shorts an outer conductor shield to an inner shield conductor of the cable successively at selected locations along an end length of the shield conductors. Some embodiments provide an RF-trap apparatus for blocking stray signals on a shielded RF cable that has two or more concentric peripheral shield conductors separated from one another by one or more electrically insulating layers, and at least one inner conductor for carrying RF signals. The RF trap apparatus includes: a first housing; and a plurality of projections configured be coupled to the first housing and to move to selectively electrically connect an outer shield conductor to an inner shield conductor by a pierce operation on the shielded RF cable.

    摘要： According to one embodiment, an active cable assembly may include a cable end, a data receiver, a controller characteristic circuit, and a controller. The data receiver, operable to receive a DC-balanced data signal, can be electrically coupled to a conductive input data line of the cable end. The controller characteristic circuit can be electrically coupled to the conductive input data line. The controller can be communicatively coupled to the data receiver. The controller may include a configurable communication port electrically coupled to the controller characteristic circuit, and memory for storing a boot loader. The controller can execute the boot loader to set the configurable communication port as an output for controller data signals and as an input for the controller data signals.

    摘要： An isolation device provides high common mode transient immunity without increasing the supply voltage rails in the transmitter side. In one aspect, the disclosed isolation device implements a self-boosting scheme to increase a voltage swing of a transmission signal under a lesser supply voltage rail. The disclosed isolation device includes a first stage circuit, a boost circuit, and a second stage circuit. The first stage circuit is configured to generate first and second signals each having a first voltage within a supply voltage range. The boost circuit is configured to provide a boosted voltage range greater than the supply voltage range responsive to at least one of the first or second signal. The second stage circuit is configured to generate an output signal based on either one of the first or second signal, such that the output signal has a second voltage within the boosted voltage range.
