VPX Board J1 Signal Assignment

VPX is defined by VITA46. VPX boards may still follows the IEEE 1101 for board size but use different connectors.
However a VPX board may also use the REDI standard [VITA 48] for a mechanical form factor.
VPX cards may be either 3U or 6U high and 160mm deep. The new VPX connector runs up to 6.26Gbps
The VPX board style defines a new direction for the VME bus standard and is not backward compatible with the VME specification.
However, manufacturers do produce backplanes that handle both VME and VPX cards.

Notice how each signal pair also has two individual ground signals, and that every other pair swaps lanes.
So a pairs of signals is only placed next to ground pins in both the rows and columns.
