Application Scenarios & Design Considerations

INTEGRATED 1394A 2000 OHCI PHY LINK LAYER CONTROLLER

Alternative Part Number

  • TSB43AB22A --: Same TSB43xx IEEE 1394 link-layer controller family with integrated PHY, pin and function compatible upgrade with improved errata.
  • TSB43AB23 --: Closely related 1394a link-layer controller from the same TI family, offering similar host interface and PHY integration for drop-in redesign.
  • TSB82AA2 --: TI 1394a link-layer controller with comparable feature set and interface, usable as a functional substitute with minor board-level changes.
  • FW322 --: Third-party IEEE 1394a link-layer controller with comparable interface and feature set, usable as an alternative source.
