The following tables describe connectors used on the MCPN750A base
board. Note that the pin assignments for connectors J3, J4, and J5 apply to
both transition modules, as well as the MCPN750A.
The MCPN750A implements a 64-bit CompactPCI interface on
connectors J1 and J2. J1 is a 110 pin AMP Z-pack 2mm hard metric type
A connector with keying for +3.3V or +5V. J2 is 110 pin AMP Z-pack
2mm hard metric type B connector. Each of these connectors conform to
the CompactPCI specification. The pinout for connectors J1 and J2 are
shown below.
