Overview
The TSB41AB3, produced by Texas Instruments, is a IEEE 1394a 3-port cable transceiver/arbiter designed to implement a three-port node in a cable-based IEEE 1394 network. This component provides both digital and analog transceiver functions necessary for packet reception and transmission. It is compatible with various link-layer controllers (LLCs) and supports transmission speeds of 100, 200, and 400 Mbits/s. The TSB41AB3 is a direct drop-in upgrade for the TSB41LV03APFP and TSB41LV03PFP, making it an ideal choice for upgrading existing systems.
