Texas Instruments TSB41AB3 Three-Port Cable Transceiver/Arbiter Datasheet

The TSB41AB3 provides the digital and analog transceiver functions required to implement a three‑port node in an IEEE 1394 network. Each port supports 100, 200 or 400 Mbps data rates and includes differential line transceivers, bias‑voltage monitoring, and optional isolation for use with a line‑layer controller.

The device features low‑power operation via a PD terminal that disables the PLL, ultralow‑power sleep mode when all ports are inactive, and a 1.86‑V bias voltage for cable termination. Pin assignments, functional block diagrams, and terminal functions are detailed for board integration.
