The PMX-P is a single site XMC/VITA 42.3 (PCI Express) to PCI/PCI-X adapter board. It enables a x1, x2, or x4 XMC/VITA 42.3 module to be plugged into any Universal PCI 2.3 32 or 64-bit PCI or PCI-X slot running at 33-133MHz with 5V I/O tolerant PCI signaling. XMC boards with a x8 PCIe width on Pn5 can also be installed but only a x4 path is supported.

The PMX-P features the Pericom PI7C9X130 PCI Express to PCI-X Reversible Bridge. Among others, the PI7C9X130 is compliant with the PCI Express Base Specification, Revision 1.1 and the PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0. PI7C9X130 supports transparent and non-transparent mode of operations.

The PI7C9X130 is used on the PMX-P as a reverse bridge (PCIe to a PCI/PCI-X host system). In reverse bridge mode, PI7C9X130 has a 64-bitPCI-X upstream port and an x4 PCI Express downstream port (2.5Gb/s data rate). PI7C9X130 configuration registers are backward compatible with standard PCI bridge software and firmware.

Pn4 (PMC) and Pn6 (XMC) rear-panel I/O connector access are both supported. Pn4 sgnals can be accessed via a standard PMC PIM (PMC I/O Module) connector. Pn6 sgnals can be accessed using an XMC connector, following the "XIM" enhancement as suggested by Extreme Engineering. Signal breakouts follow VITA 46.9.

In addition to the PIMs available for the Rastergraf AgatePXC, MerlinPXC, and MerlinMTX graphics boards, Rastergraf can supply a General Purpose Breakout PIM, the PFX-PIM, that works with both the PMF-E and PMX-P carrier boards.

To aid in debugging, the PMX-P has Test Point pins and/or LED indicators for all major on-board power sources. JTAG access is supported for both an external connector and via the PCI bus.

Jumpers allow the user to select either +5 or +12 for the XMC VPWR pins. VPWR power is limited to about 12W via a Polyswitch resettable fuse.
