NCN51XX is either a PHY-only transceiver or both MAC and PHY transceiver which handles the transmission and reception of data on the bus.

It generates from the unregulated bus voltage stabilized voltages for its own power needs as well as to power external devices. NCN51XX assures safe coupling to and decoupling from the bus and does not require external XTAL for proper operation.

NCN5110

  • bit (or PHY-only) transceiver
