PCIeBPMCX1 (PCI/PCI-X Bus Compatible) Bridge based PCIe and PMC Compatible Adapter Carrier
Front View shown with 2 installed fans model # PCIeBPMCX1-FAN12-OT


Now you can use your PMC with a new PC. The new PC´s have PCI Express connectors in larger quantities than PCI slots. The PCIeBPMCX1 ( PCIe Bridge PMC 1 slot) adapter / carrier converter card provides the ability to install one PMC card into a standard PCIe (Express) 4 lane slot. Suitable for PCI or PCI-X operation with the PMC; 32 bit or 64 bit data and PCI (25, 33, 50. 66) or PCI-X (50,66,100,133) MHz. clock. Auto selected or switch programmable speeds. The bridge can operate with 1, 2, 3, or 4 lanes active, and can be installed into slots with more than 4 lanes if desired.

Why the Tsi384 instead of the PEX8114? Most current PCIe carriers for PMC are using the PLX PEX8114 device. The Tundra Tsi384 has significantly better performance. For the details request the Tundra speed comparison document [from Tundra]. It is a confidential document so we can´t reprint the results here.

We can tell you that we ran more than 100K DMA loop-tests using the PMC BiSerial III MDS1 as a test bench. We ran the test for 54 hours and could have left it longer.... The DMA loop uses a message size of 1Mb, significantly larger than the 1K x 32 FIFO within the MDS1 design. HW moves the data between FIFO´s. DMA moves the data back again. The FIFOs are relatively small when compared to the file size being transferred. The TX and RX side have independent DMA controllers on the MDS1. There are 4 channels per MDS1. The hardware starts transferring the RX side as soon as there is data in the RX FIFO. The result is that data is being transferred in both directions using DMA across the PCIe bus. The transfers will be somewhat asynchronous to each other creating all possible conditions when allowed to run for an extended period of time.

The hardware ran Friday - Monday without error. The test operates faster than in a standard PCI slot. When you do the math an impressive amount of data was transferred and checked.

Faster, lower powered, less complex power supply requirements, higher MTBF. In short a better product. We use PLX devices on a number of our designs. In this case the Tundra part is superior. If you care about performance, when comparing PCI Express carriers check for the Tsi384 bridge.

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 PCIe mounting bracket.

For superior performance the PCIeBPMCX1 has dual cooling cutouts for increased airflow to the PMC. If your application requires a fan you can order the PCIeBPMCX1-FAN to have a fan(s) mounted to your PCIBPMCX1. The FAN positions are numbered 1-2 with 1 closest to the PCIe Bezel [left edge in the picture above]. Both fan positions can be mounted. The 2nd position can have a zero slot fan mounted where the fan does not take any extra slots. The first position can be fitted with the zero slot fan, if the PMC to be installed does not need the full 10 mm height in the connector area. If the PMC to be mounted needs to use more than 4.7 mm of the height in the connector area the standard fan - rear mounted can be used and potentially require an extra slot.

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. LEDs 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.

Local Regulation of the 3.3V power insures clean power on the 3.3V rail, and that the rail is energized. The -12V, 5V, and 3.3V for the PMC are regulated on board. The regulator designs utilize a switching regulator controlling a MOSFET to convert 12V. An LC filter insures clean power at the PMC. The bridge uses a small amount of 3.3 plus 1.2V also derived from +12 with a switching power supply. The PCIe gold fingers are rated for 1.1A each, and a total of 5.5A on the +12V rail. 59.4W are available to the card after power conversion, and about 2W is used for the Bridge leaving 57.4W for the PMC. In most cases this is enough power. The PCIeBPMC has a cable connector to allow additional 12V power to be added to the card. The two supplies are DIODE coupled. The bridge is properly bipassed with additional capacitors near the PMC connectors.

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.
