Embedded applications frequently require real time processing coupled with special purpose IO. With the PCIeBPMCX2´s two positions a PrPMC can be matched with another PMC to make a high bandwidth processing node. The PrPMC can communicate with the host for set-up, and then use the local bus to control and transfer data with the special purpose IO card. For example the PMC-BiSerial-III-ORB2 provides 2 channels each of 4 different base telemetry types with additional options plus a GPIO port. When IO is matched with a PrPMC you can control or monitor a large system in real time. With a local processing node of this nature you can use many in parallel with only one computer to provide the system management. For example - 10 in an expansion chassis without overloading the buses or management system.

PCIeBPMCX2 (PCIexpress Bridge PMC 2 slots) adapter / carrier converter card provides the ability to install two PMC cards into a standard PCIe slot. Slots with 4 or more lanes are compatible - 4, 8, 16 for example. PCIeBPMCX2 has two PMC card positions. PMC operation with 32 bit or 64 bit data and 33, 66, 100 or 133 MHz. clock. PCIeBPMCX2 can act as a transparent bridge or be programmed to allow private operations on the back side [PC] bus.

The PMC user IO connector Pn4 from both positions is brought out to one of two connectors for access (DIN IDC or SCSI II). The signals corresponding to the PrPMC [position 0] standard Ethernet and Serial lines can optionally be connected to the Ethernet and Serial port connectors at the top edge of the board. The signals are isolated with resistor packs to keep the routing short. The PMC front panel connector for slot 1 is mounted though the PCI mounting bracket.

For superior performance the PCIeBPMCX2 has two cooling cutouts per position for increased airflow to the PMC´s. If your application requires a fan you can order PCIeBPMCX2-FAN( ) to have fans mounted to your PCIeBPMCX2. FAN positions are numbered 1-4, position 1 is closest to the PCI Bezel [left edge in the picture above.] One fan can be mounted per position. Fans can be mounted to blow onto the PMC or to pull air from the PMC (R option.)

The PCIe bus is interconnected to the PMC via a bridge. The bridge can operate with 1, 2, 3 or 4 lanes in operation. For maximum performance 4 lanes are recommended. LED´s are provided to indicate the Lane status. The Secondary side of the bridge can operate with 32 or 64 bit data and PCI or PCI-X programming. The design uses a DIPSWITCH to allow selection of auto or force on the clocks. With Auto the PMC PCIXCAP and M66En signals are used to determine the clock speed. With Force, the DIPSWITCH is used to select the clock rate. 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 PMC´s installed. The PCI-X controls are also selectable via dipswitch.

The voltage definitions are buffered between the PCIe and PMC buses. PCIe is fixed LVDS levels, and the PMC VIO is set to 3.3V.

The bridge is located near the PCIe "gold fingers" and routed with PCIe specification compliant traces for impedance and length to insure maximum performance from your Express system.

The -12V, 5V, and 3.3V for the PMC are regulated on board. The power supply designs utilize switching regulators controlling a MOSFET to convert 12V. An LC filter ensures clean power at the PMC. The bridge uses a small amount of 3.3 plus 1.2V which are supplied by the PCIe 3.3V supply. The PCIe gold fingers are rated for 1.1A each, and a total of 5.5A on the +12V rail. 55W are available to the PMC´s after power conversion. Please note this is the combined power requirement across the +12, -12, +5, and 3.3V power used by the PMC´s. In most cases 55W is sufficient. PCIeBPMCX2 has a cable connector to allow additional 12V power to be added to the card. The two supplies are DIODE coupled. In some cases the 12V supply on the backplane will not be adequately routed by the PC causing voltage sag on the 12V. If this occurs use the cable connector to compensate.

The power supplies include the bulk capacitance to properly bypass the FET´s and post conversion voltage rails. In addition the PMC connectors are bypassed with a .1 uF capacitor at each power pin. The power supplies are checked with voltage monitor circuits. The LED´s are not illuminated unless the voltage is within the defined range.

The individual pins on the Jn4 (PN4) connectors for each slot are accessible by either a 68 pin SCSI connector or a 64 position DIN connector. The IO are routed with matched length, impedance controlled differential traces suitable for single ended and differential operation. We recommend using our SCSI cable and the HDEterm68 breakout block with the SCSI connector. The industry standard VME IDC connector is easy to connect to your system using DINterm64 which is a 64 position terminal strip and the DIN Ribbon Cable 64, a 64 position ribbon cable.

The PMC JTAG connections are routed to headers. Please let us know if you want these headers installed. [-JTAG]
