9-Port Mil1394 PMC OHCI Adapter Card

The 9-Port Mil1394 PMC OHCI Adapter Card (FW-3x-PMC-400T) is a PMC (PCI Mezzanine Card) available in 32/64 bit, 33/66 MHz triple-node Mil1394 channel implementation using three each of the Texas Instruments TSB82AA2 OHCI Link Layer and TSB41BA3 PHY. This transformer-coupled standard PMC form factor board has nine IEEE-1394 Beta ports, three form each PHY. All nine ports are brought out through a 68-pin high density connector.

Operate simulations and test of flight control, vehicle management systems, mission systems, or avionics with a highly integrated solution designed for high-throughput applications. Switch integration for high node/port count networks requiring transformer-coupled operation is easy and provided in this ideal cost performance solution.


  • Standard PMC 32/64-bit PMC form factor
  • Three independent OHCI IEEE-1394 Beta nodes
  • Three ports per node supporting:
    • S200╬▓ (245.76Mb/s)
    • S400╬▓ (491.52Mb/s)
  • Switch-configurable maximum connection speed:
    • S200╬▓
    • S400╬▓
  • Nine active transformer-coupled ports
  • 68-Pin high-density connector
  • Optional 36 inch, 68-pin to nine 1394 9-pin beta cables
  • Texas Instruments TSB82AA2 OHCI Link Layer Controller and TSB41BA3 PHY
  • 32/64-Bit 33/66MHz PCI host interface


  • High-density 3 PHY 9-port design
  • Uses industry standard Texas Instruments TSB41BA3 Physical Layer and TSB82AA2 1394 OHCI Link Layer Controller
  • Implemented with active transformer isolation to increase cable length and robustness
  • No power over 1394b I/O cable eliminates power and ground shift concerns
