PMC Carrier with 4 positions

Shown with optional Power Expansion connector installed. See below for RIO model photos.

PMC-MC-X4-RIO is recommended for new implementations. PMC-MC-X4 will remain in production to support previously integrated projects.

The PMC-MC-X4 adapter/carrier converter card provides the ability to install up to 4 (four) PMC cards into a small enclosure. PMC-MC-X4 has two PMC card slots mounted top and bottom to create a compact arrangement with 4 PMC slots. X4 is a complete solution with built in power supplies, thermal protection, voltage monitoring, bus arbitration, clock distribution and more.

Based on 12V or 14-40V "28V" inputs the carrier provides power supplies for the +5, +3.3, +12, and minus 12. A "Power Din 4" connector is used for power input to the X4. With the chassis version, a wall mount transformer supply is provided. The 28V supply is used to make 12V. The 12V is supplied to the PMC´s and the other supplies to generate the 3.3, 5 and -12V. The 3.3 and 5V supplies can source 10A. The -12 is a 4A supply. The power supplies are tied to an optional header to allow other co-located assets to use the X4 generated power. For example when mounting an X4, prPMC, control interface, and laser or other device controlled by the installed PMC´s. With the 12V option the 28V power supply components are not installed and a strap is used to tie the input power [12V] to the 12V plane. In this configuration the 12V will match the input power rail definition. In this version "12V ONLY" is visible in the top side silk screen.

PCI VIO is programmable allowing 5V or 3.3V PMC´s to be used. The voltage select pins are not installed [the keying holes are provided] on the PMC-MC-X4. Many PMC´s are "universal" and can work with 3.3 or 5V PCI backplanes. The DIPSWITCH selects 5V or 3V operation. The Silk-Screen has a legend with the DIP switch selection options.

The PCI bus is suitable for 32 and 64 bit operation at 33 or 66 MHz. Alternate clock frequencies can be supported by special request. Each of the slots including Slot 0 has a request and grant connection to the arbiter located within the CPLD. The CPLD also provides a selectable 66/33 MHz reference clock routed to each of the slots. The reference clock is buffered with a "zero delay" buffer and matched length routed to each of the PMC slots. Interrupts are routed from Slots 1, 2, and 3 to slot 0. IDSEL is selectable to be in the lower or upper address range via the DIPSWITCH. Reset is based on supervisor circuits checking that the 3.3V and 5V rails are valid or the reset option from the DIPSWITCH. Slots 0,1,2 and 3 are clearly marked in the silk-screen.

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 [DIPSWITCH]. 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 PMC´s 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, and 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.

A new feature available with revision B FLASH, for revision F and later boards is the ability operate in Standard or Remote mode. Using the DIPSWITCH(5) select the Remote mode to receive a clock from an external source and to use an external second level of arbitration. A net of 3 PMC positions are available in this configuration as position 0 is used for the cable between the host system and the X4 acting as an expansion chassis. Initial testing was performed with an Extendio II . PMC-BiSerial-BA16´s were used to run DMA tests on multiple positions in parallel plus do standard target IO accesses. If you have the right HW but the previous FLASH please contact Dynamic Engineering for an update.

If you have custom requirements please call or e-mail us with the details.

  • Requests and Grants routed to CPLD provided on X4. All slots can be bus masters.

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

  • Power
  • Internal Power Supplies for std model: +5(10A), +3.3(10A), +12(4A), -12V(4A) VIO supplied to PMC slots. Reference rail can be 12V or "28V" 14-40 is the range for the 28V power. 18-36 is recommended to provide margin and increase efficiency.

    Internal Power Supplies for -RIO model: +5(15A), +3.3(15A), +12(4A), -12V(4A) VIO supplied to PMC slots. Reference rail range 10-40V.

  • Power Sharing Option
  • Optional connector can be installed in place of PMC 3 [standard model - on card edge for RIO model] to provide 28V, 12V, -12V, 5V, 3.3V and ground to another piece of equipment. Mainly useful when installed in a chassis in common with other equipment which requires an external DC supply. Please note that the current used on this connector competes with the current available to the PMC´s.

  • Pn4 Interconnect
  • Pn4 for Slots 1,2,3 can be interconnected on the standard model - not available on RIO model. Signals are pre-routed with matched length differential pairs suitable for single ended or differential operation. Zero ohm reisistor packs are used to make or leave open the connections between the different slots. There are 4 signals per resistor pack - two pairs. Select which packs are installed to create buses between the 3 PMC´s with any 2 or all three connected for each rpack position.

  • VIO
  • VIO is programmable by the user. 3.3V or 5V selected with DIPSWITCH. Please note the VIO current is part of the 3.3V or 5V power budget [depending on selection made].

  • Thermal
  • PMC-MC-X4 is a low power design with minimal heat dissipation of its own. Most PMC´s will require forced air cooling. For the standard model: Switched 5V power is available for fans along with cut-outs on the side of the X4 to support closely mounted fans with little mechanical overhead. 1.5A total available between the two positions. Routed to allow full load on either position. Option for PMC control over FAN switch or DIPSWITCH control. The fan power [revision E and later] comes from a separate 5V supply. An on-board thernal switch is set to 75C and has 10C hystersis to shut off the main supply in the case of being over temperature. The fan power will continue to operate when the main power is down.

    For RIO model the FAN power is 12V and comes from a speed control device where fan speed is controlled via temperature. The over temperature control system is retained. 12 V is not disabled by the overtemperature control.

  • IO Interface
  • Front Bezel IO supported. RIO model supports both Bezel and Pn4 IO from all positions. Pn4 IO is routed with matched length, impedance controlled, differential traces between each Pn4 and matching VHDCI connector.

  • LED´s
  • +3V, +5V, +12V, -12V and "PMC Present".

  • JTAG
  • JTAG header is available to interconnect with PMC inslot 0. JTAG pin definitions are in the silkscreen.
