Abstract:
1. An electrical connector, comprising: a mezzanine-style connector housing that defines a connector mating plane and a connector mounting plane that is parallel to the connector mating plane; a first column of electrical contacts contained in the connector housing, the first column comprising a first arrangement of differential signal pairs separated from one another by first ground contacts; a second column of electrical contacts contained in the connector housing, the second column comprising a second arrangement of differential signal pairs separated from one another by second ground contacts, wherein one differential signal pair in the second arrangement of differential signal pairs is a victim differential signal pair; and a third column of electrical contacts contained in the connector housing, the third column comprising a third arrangement of differential signal pairs separated from one another by third ground contacts, wherein (i) the second column is adjacent to the first column, and the third column is adjacent to the second column; (ii) the connector is devoid of electrical shields between the first column and the second column, and between the second column and the third column; (iii) the contacts in the first column are spaced apart from the contacts in the second column by a column-spacing distance of about 1.8-2.0 millimeters, and the contacts in the second column are spaced apart from the contacts in the third column by the column-spacing distance; (iv) each of the differential signal pairs defines a gap distance between the electrical contacts that form the pair; and (v) the gap distance relative to the column-spacing distance is such that differential signals with rise times of 200 picoseconds in the six differential signal pairs in the first, second, and third columns that are closest to the victim pair produce no more than 6% worst-case, multi-active cross talk on the victim differential signal pair.
