MVME3100 Single Board Computer Installation and Use (6806800M28C)
79
4.10.5 PCI Mezzanine Card Slots
The MVME3100 provides two PMC sites that support standard PMCs or PrPMCs. Both PMC sites
are located on PCI bus B and operate at the same speed and mode as determined by the
slowest PMC module. The board routing supports a maximum of 100 MHz PCI-X operation on
each site. Signaling voltage (Vio) for the two PMC sites is dependent on keying pin installation
options and can be configured for 5V or 3.3V. Both sites must be configured for the same Vio
voltage or the Vio voltage will be disabled. Each PMC site has enough 3.3V and 5V power
allocated to support a 25 watt (max) PMC or PrPMC from either supply.
PMC slot 1 supports:
PMC slot 2 supports:
You cannot use 3.3V and 5V PMCs together; the voltage keying pin on slots 1 and 2 must be
identical. When in 5V mode, the bus runs at 33 MHz.
In addition, the PMC connectors are located such that a double-width PMC may be installed in
place of the two single-width PMCs.
