PCI to PMC Adapter / Carrier

PCIBPMCX1 (PCI/PCI-X Bus Compatible) Bridge based PCI and PMC Compatible Adapter Carrier

The PCIBPMCX1 ( PCI / PCI-X Bridge PMC 1 slot) adapter / carrier converter card provides the ability to install one PMC card into a standard PCI/PCI-X slot. The PCIBPMCX1 PMC card position can be programmed for 3.3 or 5V operation by the user, and the primary PCI bus implementation is universal voltage. Suitable for PCI or PCI-X operation with 32 bit or 64 bit data and 33, 66, 100 or 133 MHz. clock.

The PMC user IO connector Pn4 is available on a SCSI II connector. The Pn4 "user IO" is routed differentially with matched length, and impedance control to the SCSI connector. The PMC front panel connector is mounted though the PCI mounting bracket.

For superior performance the PCIBPMCX1 has cooling cutouts for increased airflow to the PMC. Fans can be mounted into the cooling holes. The fan positions are numbered 1-2 with 1 closest to the PCI Bezel [left edge in the picture above].

The PCI bus is interconnected to the PMC via a 64 bit 133 MHz capable bridge. The bridge allows the PCI bus to operate with different parameters than the PMC card - for example the PCI bus can operate at 66 MHz with 64 bit data and the PMC with 33 mhz and 32 bit data. The buffering within the bridge will take care of the rate and data matching. The local side can also operate at 133, 100. 66 or 33 MHz depending on the PMCs installed. The PCIBPMCX1 can control the M66EN signal via a dipswitch setting or the PMC can control the M66EN setting directly. The PCI-X controls are also selectable via dipswitch.

The voltage definitions are also buffered between the PCI and PMC buses. The PCI VIO automatically defines the reference levels for the primary side of the bridge. A shunt is used to control a MOSFET to select which voltage reference is used on the secondary side. A 5V PMC card can be used with a 3.3V PCI bus and vice-versa. The voltages can also be the same.

The bridge is located near the PCI "gold fingers" and routed with PCI specification compliant traces for impedance and length to insure that multiple PCIBPMCX1 cards can be installed onto the same PCI bus stub.

Local Regulation of the 3.3V power insures clean power on the 3.3V rail and that the rail is energized. The 5V supply is routed to the 5V rail and to the local regulator. The regulator design utilizes a switching regulator controlling a MOSFET to convert 5V to 3.3V. An LC filter insures clean power at the PMC. A shunt allows the user to select between the PCI supply and the local regulator. The bridge uses a maximum of 700 mA leaving 7+ amps on the 3.3V rail for the PMCs. The bridge is properly bipassed with additional capacitors near the PMC connectors.

The 5V, +12 and -12V voltages are supplied to the PMC slot via the PCI connector. The voltages are bipassed at the PCI connector and at the PMC connector. The 5V power has additional decoupling to support the regulator requirements.

The individual pins on the JN4 (PN4) connectors for each slot are accessible by a 68 pin SCSI connector. We recommend using our SCSI cable and the HDEterm68 breakout block with the SCSI connector.

The PMC JTAG connections are routed to a header. The header is configured to for discrete connections. Please let us know if you want the header installed.

    PCIBPMCX1 Benefits

  • Speed
  • PCIBPMCX1 offers PCI-X and PCI speeds on the primary and PMC slot sides.

  • Price
  • PCIBPMCX1cost effective. Make use of existing PMC designs in PCI applications without paying for the expense of a new design and layout. Quantity discounts are available.

  • Ease of Use
  • PCIBPMCX1 is easy to use. A plug and play interface to the PMC site. The Bridge can be configured with the user switches on board; eliminating any requirement for special software for the bridge itself. PCIBPMCX1 has a Non Transparent Bridge. The board comes configured for a 66 MHz capable primary bus and 33 MHz secondary bus. In most cases the switches can be left with the factory settings. The manual contains clear directions for switch options. The engineering kit provides a good starting point for a new user.
