Product Summary

The TSB43AB23 is an integrated 1394a-2000 OHCI PHY/link-layer controller (LLC) device that is fully compliant with the PCI Local Bus Specification, the PCI Bus Power Management Interface Specification (Revision 1.1), IEEE Std 1394-1995, IEEE Std 1394a-2000, and the 1394 Open Host Controller Interface Specification (Release 1.1). It is capable of transferring data between the 33-MHz PCI bus and the 1394 bus at 100M bits/s, 200M bits/s, and 400M bits/s. The TSB43AB23 provides three 1394 ports that have separate cable bias (TPBIAS). The TSB43AB23 also supports the IEEE Std 1394a-2000 power-down features for battery-operated applications and arbitration enhancements.
