PCI-104 / PC104p to PMC Adapter / Carrier
Front View

PC104p2PMC ( PCI-104 to PMC ) adapter / carrier converter card provides the ability to install a PMC card into a standard PCI-104 slot. Suitable for PCI operation with 32 bit data and 33 or 66 MHz bus operation.

The PCI bus is buffered with 10 ohm series resistors and clamped with Schottky diodes. The PC104p2PMC design is passive with no added delays to access the PMC hardware. The traces are carefully routed with proper attention paid to the impedance, and reference planes to maximize compatibility with your PCI-104 system. PC104p2PMC is based on the legacy of the PCI2PMC, PCIBPMC, and cPCI versions.

An optional connector "P1" is available for user IO from the Pn4 connector of your PMC. P1 is located in the standard connector area for PCI-104. P1 is routed to Pn4 using differential traces with matched length, and 100 ohm impedance control. Suitable for differential and non-differential IO. The connector shield can be AC/DC or open based on a user shunt. P1 has 4 "extra" pins which are selectable between open, 3.3V and ground [in pairs]. The voltage reference can be handy for low power external devices, in line terminations and loop-back fixtures.

The PCI bus interconnected to the PMC is a 66 MHz capable layout.

PCI VIO is interconnected to the PMC directly. The PCI-104 backplane will determine the bus voltage reference. The voltage select pins are not installed on the PC104p2PMC, and it is left to the user to properly select the PMC and PCI104 stack components for PCI voltage level considerations. Many PMCs are "universal" and can work with 3.3 or 5V PCI backplanes.

PC104p2PMC uses planes for power distribution between the PCI-104 stack connector and the PMC connectors [Pn1 and Pn2]. .1 uF 50V caps are provided at each of the PMC power pins plus an additional 10 uF cap on the power rails.

The stack position is selected with the dipswitch. The interrupt, IDSEL, Clock, Bus Request and Bus Grant are selected based on the stack position.

LED´s are provided for the system voltages.

PMC JTAG connections are routed to a header for use with PMC's supporting JTAG programming. For example, most Dynamic Engineering PMC´s allow reprogramming the FPGA FLASH using the PMC JTAG FPGA connections.

PC104p2PMC Features

  • Size
  • Standard hole pattern for PCI-104 or PC/104p card. The card is longer in the direction of the ISA connector position.

  • PMC compatible slot
  • 1 PMC Slot provided.

  • Clocks
  • PCI bus can operate at 66 or 33 MHz. The PMC must be 66 MHz capable for 66 MHz operation to work properly.

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

  • Software Interface
  • PMC register definitions as defined by installed hardware. No software set-up required by PC104p2PMC.

  • Interrupts
  • INTA, B, C, D routed to PCI-104 / PC/104p connector from PMC.

  • Signal Conditioning
  • AD signals are series terminated with 10 ohm resistors. Schottky clamping Diodes on critical PCI signals. Zero delay buffer for PCI clock distribution.

  • Power
  • +5, +3.3, +12, -12V supplied to PMC. Power is filtered with decouplers on each PMC power pin plus bulk.

  • VIO
  • PCI IO Voltage is set by the PCI backplane. VIO is routed from the PCI-104 connector to the PMC.

  • IO Interface
  • Front Bezel IO supported. Optional Pn4 "rear" IO is also available. Pn4 IO is routed with matched length, impedance controlled differential traces.

  • LED´s
  • PCI3.3, +3V, +5V, +12V, -12V and Busmode 1.

  • JTAG
  • PMC JTAG connections are routed to a header. JTAG pin definitions are in the silkscreen. Handy for use with PMC's supporting JTAG FPGA programming.

    PC104p2PMC Benefits

  • Speed
  • With the PC104p2PMC direct connect to the PCI bus the latency to the PMC is optimized. Your data will move quickly and reliably through the PCI bus to and from your hardware.

  • Price
  • The PC104p2PMC has an attractive price point. Make use of existing PMC designs in PCI-104 and PC/104p applications without paying for the expense of a new design and layout. Quantity discounts are available.

  • Warranty
  • 1 year warranty

  • Ease of Use
  • PC104p2PMC is easy to use. A plug and play interface to the PMC site.

  • Availability
  • PC104p2PMC is a popular board. We keep the PC104p2PMC in stock. Send in your order and in most cases have your hardware the next day.

  • Size
  • PC104p2PMC is a non-standard size PCI-104 board. The connector and mounting points are in the standard stack mounting locations. The board is elongated to add support and mounting positions for the installed PMC.

  • PMC Compatibility
  • PC104p2PMC is PMC compliant per the IEEE 1386 specification. All Dynamic Engineering PMC Modules are compatible with the PC104p2PMC. All other PMC Modules which are compliant with the PMC specification will be compatible with the PC104p2PMC.

  • PCI Compatibility
  • PC104p2PMC is PCI compliant. PC104p2PMC is routed as an extension of the stack. The trace lengths, impedance and otehr routing characteristics are controlled to provide a reliable PCI connection at the PMC connector. Since the trace length with the PMC installed will be longer than a standard PC104p card, the PC104p2PMC design includes 10 ohm series resistors, and clamping diodes help to control the AD and control signals. PC104p2PMC adapters can be expected to work in any PCI bus stub.
