Model-specific signals

While the local bus protocol is in general the same in each of the models in the XRC range, in earlier models such as the ADM-XRC, some signals in the generic model of the local bus are actually two different signals that driven by the FPGA and the local bus bridge respectively. The function of these signals however, is the same. This section details the differences between the models of the XRC range:

ADM-XRC

ADM-XRC-P

ADM-XRCII-Lite

ADM-XRCII

ADM-XRCIIPro-Lite

ADM-XRC and ADM-XRC-P

The following figure shows the connections between the PCI9080 local bus bridge and the FPGA in an ADM-XRC or ADM-XRC-P card:

ADM-XRCII-Lite

The following figure shows the connections between the PCI9080 local bus bridge and the FPGA in an ADM-XRCII-Lite card:

ADM-XRCII

The following figure shows the connections between the PCI9656 local bus bridge and the FPGA in an ADM-XRCII card:

ADM-XRCIIPro-Lite

The following figure shows the connections between the local bus bridge and the FPGA in an ADM-XRCIIPro-Lite card; note that the local bus is capable of operating in 32-bit or 64-bit mode.
