Application Scenarios & Design Considerations

1394 Link Layer Controller With DTCP Content Protection for Consumer Electronics Applications

Alternative Part Number

  • TSB43AA82 --: Same TSB43xx IEEE 1394 link-layer controller family with comparable 1394a functionality, widely used as a drop-in replacement in FireWire designs.
  • TSB41AB3 --: TI 1394a three-port PHY/link companion device that pairs with the same host interface and is commonly substituted in 1394 subsystem designs.
  • FW323 --: Third-party IEEE 1394a link-layer controller offering equivalent 1394 bus interface functions, usable as a cross-vendor alternative when TI parts are unavailable.
  • TSB43AA22 --: TI 1394a link-layer controller with integrated PHY interface, functionally similar to the TSB42AA4 and widely used as a substitute in FireWire link applications.
  • TSB12LV32 --: TI IEEE 1394 link-layer controller with similar host/PHY interface architecture, suitable as an alternative when the TSB42AA4 is unavailable, though pinout should be verified.
  • FW322 --: Third-party IEEE 1394a link-layer controller offering equivalent FireWire link functionality, usable as a cross-vendor alternative for 1394 designs.
