Appendix B PCI Mezzanine Card (PMC) slot
The PCI Mezzanine Card (PMC) Interface is an additional slot for parallel
mounted add on cards. The interface is compliant to the IEEE 1386.1
specification and is based on the electrical and logical layer of the PCI
specification. PMC Slot1 is 66/100/133 MHz PCI-X capable. PMC Slot 2 is 33
MHz/32 bit only. The user definable I/O Pins are connected to the rear IO
connector on the VR11, as defined in the VITA 36 specification.
•
A 5 V key is mounted on PMC2, for 5 V compatible PMC cards.
•
A 3 V key is mounted on PMC1, for 3.3 V compatible PMC cards.
