To take advantage in advances in serial data transmission technologies, PICMG is upgrading its popular CompactPCI® standard. PICMG’s draft standard 2.30 creates a pin-out for the J2 connector that supports multiple serial protocols and calls out the 3M™ Ultra Hard Metric (UHM) Socket Connector. This new connector provides the much improved signal integrity performance required to transmit multiple high speed protocols, while still mating to a standard 2mm HM backplane header.
