An electrical connector having a leadframe housing, a first electrical contact fixed in the leadframe housing, a second electrical contact fixed adjacent to the first electrical contact in the leadframe housing, and a third electrical contact fixed adjacent to the second electrical contact in the leadframe housing is disclosed. Each of the first and second electrical contacts may be selectively designated, while fixed in the lead frame housing, as either a ground contact or a signal contact such that, in a first designation, the first and second contacts form a differential signal pair, and, in a second designation, the second contact is a single-ended signal conductor. The third electrical contact may be a ground contact having a terminal end that extends beyond terminal ends of the first and second contacts.

What is claimed: 1. An electrical connector, comprising: a plurality of differential signal contact pairs arranged along a first centerline, a second centerline, and a third centerline, the first centerline arranged adjacent and parallel to the second centerline and the third centerline arranged adjacent and parallel to the second centerline, wherein (i) each of the plurality of differential signal pairs comprises two electrical contacts; (ii) the two electrical contacts each define a broadside and an edge and are arranged broadside-to-broadside along at least a majority of the length of the signal pair; (iii) each of the differential signal pairs arranged along the second centerline are offset from differential signal pairs arranged along the first centerline and the differential signal pairs arranged along the third centerline; (iv) the electrical connector is devoid of shields between the first centerline, the second centerline, and the third centerline; (v) a ground contact is positioned at one end of the first centerline and on an opposite end of the second centerline; and (vi) adjacent rows of the signal pairs are staggered in a row direction that is perpendicular to a line direction along which the centerlines extend such that no signal pair of one row aligns with any signal pair of an adjacent row in the line direction. 2. The electrical connector of claim 1, wherein a 0.3 to 0.4 mm gap is defined between each of the two electrical contacts. 3. The electrical connector of claim 1, wherein one of the plurality of differential signal pairs has an impedance of 100Ω, plus or minus ten percent. 4. The electrical connector of claim 1, further comprising ground contacts arranged along the first centerline, the second centerline, and the third centerline. 5. The electrical connector of claim 1, wherein the plurality of differential signal contact pairs arranged along the first centerline terminate in solder balls. 6. The electrical connector of claim 1, further comprising a second ground contact arranged at one end of the second centerline. 7. The electrical connector of claim 6, wherein the ground contact and the second ground contact are arranged on opposite ends of the first centerline and the second centerline. 8. An electrical connector comprising: a plurality of differential signal contact pairs arranged along a first row, a second row, and a third row, the first row arranged adjacent and parallel to the second row and the third row arranged adjacent and parallel to the second row, wherein (i) each of the plurality of differential signal pairs comprises two electrical contacts; (ii) the two electrical contacts each define a broadside and an edge and are arranged broadside-to-broadside along at least a majority of the length of the signal pair; (iii) each of the differential signal pairs arranged along the second row are offset from differential signal pairs arranged along the first row and the differential signal pairs arranged along the third row; (iv) the electrical connector is devoid of shields between the first row, the second row, and the third row; (v) a ground contact is positioned at both ends of the first row and at both ends of the third row; and (vi) adjacent rows of the signal pairs are staggered in a first direction along which the rows extend such that no signal pair of one row aligns with any signal pair of an adjacent row in a second direction that is perpendicular to the first direction. 9. The electrical connector of claim 8, wherein a 0.3 to 0.4 mm gap is defined between each of the two electrical contacts. 10. The electrical connector of claim 8, wherein one of the plurality of differential signal pairs has an impedance of 100Ω, plus or minus ten percent. 11. The electrical connector of claim 8, further comprising additional ground contacts arranged along the second row. 12. The electrical connector of claim 8, wherein the plurality of differential signal contact pairs arranged along the first centerline terminate in solder balls.
