The Mezzanine PMC Carrier is an optional extension card that provides three 5v 33MHz PMC sites
to the M52xx boards. The assembly of the PMC Carrier and a M52xx board requires two adjacent
VME slots.
These additional PMC sites share a single PCI segment, which is bridged to the Quarternary PCI
bus via a transparent P2P bridge.
Note – The Mezzanine PMC Carrier provides three 5v PMC sites. The two PMC sites on the
M52xx are 3.3v If 3.3v PMC sites are required on the PMC Carrier please contact
VMETRO.
