Abstract: A small form-factor, high performance connector is disclosed. This connector is intended for use with high bandwidth digital video, implementing differential digital signaling, as well as for high bandwidth analog video. The described connector system performs the function of the Digital Visual Interface (DVI) connector, but in a significantly smaller package. Signal integrity is maintained in the smaller form factor by the expedient assignment of signals to pins so that the pin above or below any signal is not used on that interface, thus reducing the chances for signal crosstalk. The pin shape and spacing are created to match pin lengths and minimize inductance while maintaining the proper impedance up to 2.5 GHz. This connector system also implements a tactile feedback mechanism to aid with cable plug insertion, and incorporates a keying mechanism to prevent reverse-plugging.
