Triple-Port 1394b PCI OHCI Adapter Card

The Triple-Port 1394b PCI OHCI Adapter Card (FW-32-PCI-400) is a 32-bit, 33 MHz PCI single-node 1394b OHCI adapter implementation using the Texas Instruments TSB12LV26 OHCI Link Layer and TSB41BA3 PHY. The SWAP-optimized solution arrives non-transformer-coupled in a standard PCI form-factor board with three IEEE-1394 Beta ports. This 1394b PCI card delivers users an interface for flight control, vehicle management systems, mission systems or avionics simulation applications within a single channel.  Configurable switches allow the maximum port speed/mode to be set to S100β, S200β or S400β.


  • Single OHCI IEEE-1394 Beta node
  • IEEE-1394-2008 compliant
  • Three Beta only ports per node supporting:
    • S100╬▓ (122.88Mb/s)
    • S200╬▓ (245.76Mb/s)
    • S400╬▓ (491.52Mb/s)
  • Configurable maximum connection speeds of:
    • S100╬▓
    • S200╬▓
    • S400╬▓
  • Three IEEE-1394 Bilingual Connectors
  • Texas Instruments TSB12LV26 OHCI Link Layer Controller and TSB41BA3 PHY
  • 32-Bit, 33 MHz PCI support


  • Uses industry standard Texas Instruments TSB41BA3 Physical Layer and TSB12LV26 1394a OHCI Link Layer Controller
  • Implemented without transformer isolation to reduce costs
  • No power over 1394b I/O cable eliminates power and ground shift concerns
