Plug connector having crosstalk compensation
A plug-in connector that can be manufactured using MID technology, which nevertheless ensures good crosstalk compensation and thus a high data transmission rate has two assembled contact carrier parts with contacts are disposed between these contact carrier parts. A separate, electrically conductive compensation coating may be provided in each contact carrier part, each having a connection surface for producing an electrically conductive connection to an associated contact. Each of the electrically conductive compensation coatings has at least one coupling surface for a targeted capacitive coupling with one or more further contacts. Between each coupling surface and the associated contact, an insulating film or part of an insulating film is provided, which acts as a dielectric and a spacer. By selection of the contacts to be coupled and the capacitance of the coupling, good compensation of undesired crosstalk can thus be achieved in a simple manner.
Communications jack having a flexible substrate with a cantilevered finger with a crosstalk compensation circuit
Communications jacks include at least first through third jackwire contacts and a flexible substrate that has a first finger and a second finger. The first jackwire contact and the third jackwire contact are each mounted on the first finger and the second jackwire contact is mounted on the second finger.
CAPACITIVE STRUCTURES FOR CROSSTALK REDUCTION
One embodiment provides an apparatus. The apparatus includes a dual in-line memory module (DIMM). The DIMM includes at least one memory module integrated circuit (IC); a DIMM printed circuit board (PCB); a plurality of DIMM PCB contacts; and a capacitive structure. Each DIMM PCB contact is to couple the memory module IC to a respective DIMM connector pin. The capacitive structure is to provide a mutual capacitance between a first DIMM connector signal pin and a second DIMM connector signal pin.

MULTISTAGE CAPACITIVE CROSSTALK COMPENSATION ARRANGEMENT
Methods and systems for providing crosstalk compensation in a jack are disclosed. According to one method, the crosstalk compensation is adapted to compensate for undesired crosstalk generated at a capacitive coupling located at a plug inserted within the jack. The method includes positioning a first capacitive coupling a first time delay away from the capacitive coupling of the plug, the first capacitive coupling having a greater magnitude and an opposite polarity as compared to the capacitive coupling of the plug. The method also includes positioning a second capacitive coupling at a second time delay from the first capacitive coupling, the second time delay corresponding to an average time delay that optimizes near end crosstalk. The second capacitive coupling has generally the same overall magnitude but an opposite polarity as compared to the first capacitive coupling, and includes two capacitive elements spaced at different time delays from the first capacitive coupling.

COMMUNICATION JACK HAVING A DIELECTRIC FILM BETWEEN PLUG INTERFACE CONTACTS
Embodiments of the present invention relate to designs for network jacks which can be used for cable connectivity. In an embodiment, the present invention is an RJ45 jack that utilizes a thin dielectric film between two layers of PICs that provide crosstalk compensation by way of their geometry. Compensation is achieved by way of capacitor plates which sandwich a thin dielectric film. This allows for the layers of PICs to be in close proximity and achieve higher coupling where desired, allowing a greater amount of compensation to occur close to the plug/jack contact point. This can have the effect of moving compensation closer to the plug/jack contact point, which in turn may reduce the amount of compensation needed further along the data path.
