Overview
The TSB41LV03AIPFP, produced by Texas Instruments, is a three-port cable transceiver/arbiter designed for IEEE 1394a networks. This component is part of the FireWire™ family and is fully interoperable with 1394a standards. It provides the necessary digital and analog transceiver functions to implement a three-port node in a cable-based IEEE 1394 network. The device is compatible with various link-layer controllers (LLCs) and supports data transmission speeds of 100, 200, and 400 Mbits/s (S100, S200, and S400 respectively).
