PDI1394P23 2-port/1-port 400 Mbps physical layer interface

PDI1394P23 2-port/1-port 400 Mbps physical layer interface

The PDI1394P23 provides the digital and analog transceiver functions needed to implement a two/one port node in a cable-based IEEE 1394–1995 and/or 1394a–2000 network. Each cable port incorporates two differential line transceivers. The transceivers include circuitry to monitor the line conditions a.
