In some implementations, a method includes analyzing an amount of data communicated by a set of network interfaces. The data communicated by the set of network interfaces is processed by a set of functional units and a set of queues includes the data communicated by the set of network interfaces. The method also includes activating a first functional unit of the set of functional units when a first size of a first queue of the set of queues is above a first threshold. The method further includes deactivating the first functional unit of the set of functional units when the first size of the first queue of the set of queues is below a second threshold. The method further includes causing the data to be forward to one or more active functional units via a data interconnect coupled to the set of network interfaces and the set of functional units.

An apparatus is described for suppressing EMI emissions in an electrical device. In one example, the apparatus includes absorbing material surrounding at least a portion of an electrical component and electrically conductive material configured to contact at least one side of the absorbing material.

Shield to improve electromagnetic interference (EMI) suppression capability

An electromagnetic interference (EMI) gasket is provided that includes a resiliently-flexible and conductive outer shell, a cushioning element disposed in the outer shell, and at least one magnetic component disposed in the outer shell configured to magnetically couple to a conductive surface of an electronic device chassis.

An electrical device includes a core structure having a first core section, a second core section, and a third core section. The electrical device further includes a first coil electrically coupled to the first core section and the second core section to form a choke and a primary winding of a transformer. The choke is configured to reduce common mode noise for an electrical signal received by the electrical device, and the primary winding of the transformer is configured to induce a magnetic field on the third core section. The electrical device also includes a second coil electrically coupled to the third core section, which forms a secondary winding of the transformer and receives electromagnetic energy from the magnetic field induced by the primary winding of the transformer.

A shield is described for minimizing leakage of electromagnetic waves from a connector/chassis interface. The shield includes a conductive strip sized to at least partially surround an aperture in a chassis, where the chassis receives a connector port assembly through the aperture. The conductive strip includes an outer portion affixed to an interior surface of the chassis, and an inner portion able to be manipulated to at least partially cover one or more gaps between the connector port assembly and the chassis.

Presented herein is a modular connector with electromagnetic interference suppression. The modular connector includes a substrate, at least one set of spring pins, and a ferrite component. Each spring in the at least one set of springs includes a first portion adjacent the substrate and a second portion extending away from the substrate. The ferrite component surrounds the at least one set of spring pins, couples the at least one set of spring pins to the substrate, and is configured to suppress electromagnetic interference.

Techniques are provided for electrically connecting components on a printed circuit board (PCB), semiconductor chip package, or other electronic device. More specifically, a first component, configured to generate a differential signal, is disposed on the PCB, while a second component, configured to receive the differential signal from the first component, is also disposed on the PCB. A differential conductor pair comprising first and second parallel conductors extends along a path between the first and second components. The path of the differential conductor pair comprises at least one turn that causes a change in direction of the first and second conductors. The first conductor comprises at least one localized skew compensation bend disposed at the turn such that, at the end of the turn, the first and second conductors have substantially the same length with respect to the first component.
