MCPN750A Connector Pin Assignments

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.

MCPN750A CompactPCI Bus Connectors (J1/J2)

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.
