TSB81BA3DI IEEE 1394b THREE-PORT CABLE TRANSCEIVER/ARBITER

The TSB81BA3D provides the digital and analog transceiver functions needed to implement a three-port node in a cable-based IEEE 1394 network. Each cable port incorporates two differential line transceivers. The transceivers include circuitry to monitor the line conditions as needed for determining connection status, for initialization and arbitration, and fo.
