The TSB41LV03A 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 for packet reception and transmission. The TSB41LV03A is designed to

interface with a line layer controller (LLC), such as the TSB12LV21, TSB12LV22, TSB12LV23, TSB12LV31,

TSB12LV41, TSB12LV42, or TSB12LV01A.
