TSB43AB22APDT

IC, 1394A LINK LYR CNTLR 128-TQFP.

The TSB43AB22APDT is a Link Layer Controller (LLC) integrated with 1394a, 400Mbps and 2-port physical layer (PHY). It is capable of transferring data between the 33MHz PCI bus and the 1394 bus at 400Mbps. The TSB43AB22A device provides two 1394 ports that have separate cable bias (TPBIAS). The TSB43AB22A device also supports the IEEE standard 1394a-2000 power-down features for battery-operated applications and arbitration enhancements. As required by the 1394 open host controller interface specification (OHCI) and IEEE standard 1394a-2000, internal control registers are memory-mapped and non-prefetchable. The PCI configuration header is accessed through configuration cycles specified by PCI and it provides plug-and-play (PnP) compatibility. Furthermore, the TSB43AB22A device is compliant with the PCI bus power management interface specification as specified by the PC 2001 design guide requirements. The TSB43AB22A device supports the D0, D1, D2 and D3 power states.
