  • Publication number: 20060286866
    Abstract: In a first aspect, a method is provided for terminating a shield of a cable. The method includes the steps of (1) exposing a periphery region of the shield along a first portion of the cable; (2) coupling an electrically-conductive housing including an electrically-conductive gasket around the exposed periphery region; (3) applying a force to and maintaining the force on the gasket such that the gasket is forced against and remains in contact with an interior region of the housing and the exposed periphery region of the shield; and (4) coupling an exterior region of the housing to an electrically-conductive enclosure of an electronic product to which the cable is coupled. Numerous other aspects are provided.

  • Publication number: 20060232354
    Abstract: A device, system, and method for suppressing electromagnetic interference (EMI). In one embodiment, an EMI suppression device includes a compound ferrite core having an inner ferrite core and an outer ferrite core. The inner core includes a through hole in which a conductor may be mounted, and the outer core includes a hole in which said inner core is mounted in a concentrically offset manner. The outer core is rotatably adjustable with respect to the inner core in a manner such that the ferrite circuit cross-section area may be varied. The magnetic reluctance of the compound core is controlled in accordance with EMI suppression requirements by adjusting the circuit cross-section area.

  • Publication number: 20060125086
    Abstract: A modular heat sink decoupling capacitor array includes a plurality of modules, each defining parallel distributed decoupling plates, and each module forming a heat sink fin. Each module includes multiple spaced apart contacts for providing low inductance connections with an associated device. A power distribution interposer module is attached to a heat sink surface of the modular decoupling capacitor. The interposer module is used for implementing power delivery without using valuable ball grid array (BGA) connections and printed circuit board (PCB) layers.

  • Publication number: 20060103080
    Abstract: The transferrable EMI gasket assembly utilizes a carrier with a pair of arms, each attached to a back panel by a hinged connection and extending in the same direction to overlie one another. The conductive, deformable gasket material is attached to the carrier and positioned adjacent the back panel. The assembly is collapsed for installation with the back panel overlying one of the arms hinged thereto to present a reduced height. The assembly is placed in the operative position by moving one arm relative to the other to pivot the carrier back panel to a near right angle position with respect to the carrier arms. In the operative position, the gasket material is compressed and deformed against the confronting surfaces to effect the EMI seal while the biasing force of the compressed gasket material, in the preferred embodiment, secures the carrier arms together.

  • Publication number: 20060023874
    Abstract: A method and multiple line scrambled clock architecture with random state selection are provided for implementing lower electromagnetic emissions. A clock distribution circuit receives a clock input and generates a plurality of scrambled sequences, each respectively coupled by one of a plurality of N clock distribution lines to a destination circuit. An exclusive OR connected to the N clock distribution lines unscrambles the plurality of scrambled sequences at the destination circuit. The plurality of scrambled sequences includes multiple bit clock representations, for example, 3 bit clock representations. The presence of 1s and 0s on each of the multiple N clock distribution lines is a substantially uniform distribution. The scrambled sequences are generally pseudorandom sequences.

  • Publication number: 20060011369
    Abstract: A method and components are provided for implementing EMC shielded resonance damping of a printed circuit board. The EMC shielded resonance damping component includes a capacitor and resistor formed in series combination and contained within a shielded enclosure. A pair of coaxial pads is provided for connection to the printed circuit board. The series combination of the capacitor and resistor is connected between a first pad of a pair of coaxial pads and an interior wall of the shielded enclosure. The shielded enclosure provides a return current path to a second pad of the pair of coaxial pads through the series components.

  • Publication number: 20050285708
    Abstract: Ferrite cores are provided with rounded, convex head ends and complimentary rounded, concave tail ends. The configuration of the head and tail ends permits a reduction in gap width between adjacent cores when they are joined together into a core assembly that suppresses electromagnetic interference emitted from a cable.

In one aspect of the invention, the cable clamp includes a first conductive plate and a second conductive plate. Each of the plates has at least one groove formed therein. The first plate is positionable against the second plate so that the groove in the first plate and the groove in the second plate collectively form a hole extending from one edge of the cable clamp to an opposite edge of the cable clamp, with the hole accommodating the cable therein. In another aspect of the invention, the cable clamp includes a conductive flexible fabric having at least one pattern formed therein, with the pattern accommodating the cable therein.
