PMC-MC-X2
PMC Carrier with 2 Positions - Front View


2 slot PMC Compatible Adapter Carrier - Rear View





The PMC-MC-X2 adapter / carrier converter card provides the ability to install up to 2 (two) PMC cards into a small enclosure. The PMC-MC-X2 has one PMC card slot mounted front and and one mounted rear to create a compact arrangement with 2 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. Arbitration is accomplished with a CPLD mounted to the card. The CPLD also provides a selectable 66/33 MHz reference clock to be 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-X2. Many PMC´s 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-X2 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. The power to the PMC slots is fuse protected. 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. Dynamic Engineering offers a wall mounted transformer style external power supply. Please make sure your power supply has sufficient current to handle the load and in-rush current. The power supplies are phased to minimize the in-rush requirement by turning on the 3.3 first, 5V second, -12V third.

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-X2 components. The X2 has been designed with convection cooling in mind. The slots in the side of the PMC MC X2 design are for fans. [ Please refer to the pictures above. ] The PMC MC X2 has switched power [+5V] 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 X2 Chassis comes with twin fans making use of the cutouts. The X2 chassis comes with cutouts on the opposite side to provide for proper air flow across the PMC´s and PMC-MC-X2. A similar configuration is recommended when using the PMC-MC-X2 with an alternate chassis. Please refer to the picture of the open X2 chassis toward the bottom of the PMC MC X2 Chassis page.

Need more slots - please consider the PMC-MC-X4 version with 4 PMC slots. Custom versions made to order!

Dynamic Engineering has a chassis available to go with the PMC MC X2 to make a complete solution. Please click here or use the Java menu to navigate to the PMC MC X2 Chassis page.

PMC-MC-X2 Features

  • Size
    		•  Custom. Slightly larger than a PMC

  • PMC compatible slots
    		•  2 PMC Slots provided.

  • Clocks
    		•  cPCI bus can operate at 66 or 33 MHz. The PMC must be 66 MHz capable for 66 MHz operation to work properly. User switch to allow or disable 66 MHz. operation.

  • Access Width
    		•  Standard PCI byte lanes supported for byte, word and long access dependent on installed PMC. 64 or 32 bit operation supported.

  • Software Interface
    		•  PMC register definitions as defined by installed hardware. No software set-up required by PMC-MC-X2.

  • Interrupts
    		•  INTA, B, C, D routed to cPCI connector from PMC. Slot 0 is assumed to be populated with a PrPMC.

  • Signal Conditioning
    		•  PCI signals are routed and terminated IAW the PCI specification.

  • Power
    		•  +5, +3.3, +12, -12V VIO supplied to PMC slots.

  • VIO
    		•  VIO is programmable by the user with a shunt.

  • Thermal
    		•  The PMC-MC-X2 is a low power design with minimal heat dissipation of its own. Most PMC´s will require forced air cooling. Switched 5V power is available for fans along with cut-outs on the side of the X2 to support closely mounted fans with little mechanical overhead.

  • IO Interface
    		•  Front Bezel IO supported.

  • LEDs
    		•  +3V, +5V, +12V, -12V and "PMC Present".

  • JTAG
    		•  JTAG header connected to PMC supplied. JTAG pin definitions are in the silkscreen.
