PMC-MC-X4
PMC Carrier with 4 positions - Front View


4 slot PMC Compatible Adapter Carrier - Rear View





The PMC-MC-X4 adapter / carrier converter card provides the ability to install up to 4 (four) PMC cards into a small enclosure. The PMC-MC-X4 has two PMC card slots mounted front and rear to create a compact arrangement with 4 PMC slots. Suitable for 32/64 with 33/ 66 MHz bus operation. The carrier provides power supplies for the +5, +3.3, +12, and minus 12 from a 12V wall mount transformer supply. The X4 has an option for a "28V" power supply input. 14-34V power can be used with the higher voltage option. Arbitration is accomplished with a CPLD mounted to the card. The CPLD also provides a selectable 66/33 MHz reference clock to routed to each of the slots.

The PCI VIO is programmable allowing 5V or 3.3V PMCs to be used. The voltage select pins are not installed on the PMC-MC-X4. Many PMCs are "universal" and can work with 3.3 or 5V cPCI backplanes. A shunt is provided for the user to select 5V or 3V operation.

The PMC-MC-X4 follows the PMC specifications for maximum power consumption and heat dissipation. The power is routed from the power supplies to PMC connectors with mini-planes each of which is rated for more than the maximum PMC draw. 3.3, 5, VIO, +12, -12. The total power dissipation is limited to the external power supply capabilities. Each rail can draw to the maximum to cover situations where the power utilization is not balanced. 8A max current on 5V, 8A max current on 3.3V, 4A max current on -12. 4A at PMC slots from +12V. Power is connected to the board through a standard 2.5 MM barrel connector. The input power is overvoltage protected with a transorb located near the power switch. Please make sure your power supply has sufficient current to handle the load and in-rush current. The 8A rating can be increased to 10A. Please contact Dynamic Engineering for this option.

The X4 has an option to add a 12V power supply ahead of the other voltages. The 12V supply has a wide input range [14-34V] and can supply all of the current for the down stream supplies plus the 12V output. Suitable for higher voltage battery operation, Aircraft power etc. A 28V 5A supply is available with the high voltage option. With the 28V supply more than twice the wattage is available to the internal supplies.

PrPMC´s frequently have concentrated power consumption requiring air flow for proper cooling. The larger load also puts a thermal load on the PMC-MC-X4 components. The X4 has been designed with convection cooling in mind. The slots in the side of the PMC MC X4 design are for fans. [ Please refer to the pictures above. ] The PMC MC X4 has switched power [+5V, 1.5A] for fans plus an available override for always on. The PrPMC can control the fans with a pin on the Pn4 IO connector. If your PrPMC does not have a temperature sensor or control feature the always on mode can be selected.

The PMC MC X4 Chassis comes with twin fans making use of the cutouts. The X4 chassis comes with cutouts on the opposite side to provide for proper air flow across the PMC´s and PMC-MC-X4. A similar configuration is recommended when using the PMC-MC-X4 with an alternate chassis. Please refer to the picture of the open X2 chassis toward the bottom of the PMC MC X4 Chassis page.

If you need to interconnect the PMCıs without using the PCI bus for higher bandwith or specialized signaling the X4 has a selection matrix to interconnect the Pn4 connectors on slots 1,2,3 as required. The connections are designed for high speed use with reference planes, proper trace and space matched length routing. Suitable for high and low speed signals as well as differential pairs.
