Abstract: Methods and apparatus for reducing electromagnetic interference resultant from data transmission over a high-speed audio/visual interface. In one embodiment, an HDMI source device is disclosed. The HDMI source device includes a wireless interface and an HDMI interface coupled with an active filter circuit topology. The active filter circuit topology includes a pair of differential signal lanes; a passive filter circuit disposed within each of the pair of differential signal lanes; a plurality of active filter circuits, with at least a first active filter circuit disposed on one side of the passive filter circuit and at least a second active filter circuit disposed on the other side of the passive filter circuit; a plurality of diodes, with each of the plurality of active filter circuits coupled with a respective diode; and switching logic coupled with the plurality of diodes. Methods of operating the HDMI source device and HDMI systems are also disclosed.

Abstract: Connector inserts and receptacles that provide signal paths having desired impedance characteristics. One example may provide a connector system having a connector insert and a connector receptacle. Contacts in the connector insert may form signal paths with corresponding contacts in the connector receptacle. Additional traces in the connector insert and receptacle may be part of these signal paths. The signal paths may have a target or a desired impedance along their lengths such that the power paths electrically appear as transmission lines. Constraints on physical dimensions of the connector insert and connector receptacle contacts may result in variations in impedance along the signal paths. Accordingly, embodiments of the present invention may provide structures to reduce these variations, to compensate for these variations, or a combination thereof.

Abstract translation: 提供具有所需阻抗特性的信号路径的连接器插件和插座。 一个示例可以提供具有连接器插件和连接器插座的连接器系统。 连接器插入件中的触点可以形成具有连接器插座中的相应触点的信号路径。 连接器插件和插座中的附加迹线可以是这些信号路径的一部分。 信号路径可以沿其长度具有目标或期望的阻抗，使得功率路径电显示为传输线。 对连接器插头和连接器插座触点的物理尺寸的约束可能导致沿着信号路径的阻抗变化。 因此，本发明的实施例可以提供减少这些变化的结构，以补偿这些变化或其组合。
