Description
The TSB43LV81 provide a high-performance IEEE1394-1995 and IEEE1394.a interface with capability transfer and
receive up to 400Mbps proper-formatted packet. The TSB43LV81 have high-performance internal SBP-2 Protocol
engine, and it can provide high speed ORB exchange between SBP-2 initiators and own node. That means this
TSB43LV81 act as SBP-2 target node. Data packet FIFO has 4096Byte at maximum and Command FIFO has 512Byte at
maximum.
The TSB43LV81 can be used for another purpose such as DPP (Direct Printer Protocol) by address sorting for received
packet. Address filtering for in coming write request packet can correctly sort data packet that sent by peer DPP devices.
Both two protocols could be existing in this TSB43LV81 in same time, and internal ConfigRom CSR can correctly
response for peer Initiator or DPP device.
By above internal high performance feature, external controller can easily make SBP-2 target device and DPP devices.
This document is not intended to serve as tutorial on the 1394, SBP-2, and DPP protocol. User should refer each
documentation.
