The Rastergraf PMA-C is a PMC-to-CompactPCI adapter board. It enables any 32-bit or 64-bit PMC (PCI Mezzanine Card) module to be plugged into a standard 3U or 6U CompactPCI slot. It provides the full 64-bit interconnect between the CompactPCI J1 and J2 and the PMC connector set.

The PMA-C is designed to function as a transparent extension to the PCI bus. As such, it is a passive adapter board and has no PCI-to-PCI bridge. Thus, the carrier’s PCI bus is connected directly to the PMC card’s PCI bus. Because this results in long than normal PCI traces, it is best not to use more than one PMA-C in a backplane segment, and it should be installed in the end slot of the backplane, farthest from the CPU.

To aid in debugging, the PMA-P has Test Point pins and LED indicators for BUSMODE1, +12V, -12V, +5V, +3.3V and VIO. It also has a connector for the JTAG port. PMC Index Pin holes are provided for both 3.3V and 5V PMC signaling pins so that the PMA-P can be configured for either bus environment. Jumpers can be installed to enable 66 MHz mode, and to set PCI PRSNT and PMC BUSMODE.
