VPX Board J0 Signal Assignment

VPX is defined by VITA46. VPX boards may still follows the IEEE 1101 standard 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 VPX board style defines a new direction for the VME bus standard and is not backward compatible with the VME specification. The new VPX connector allows signal to run up to 6.26Gbps.
However, manufacturers do produce backplanes that handle both VME and VPX cards.
