onsemi NCN26010 Industrial Ethernet Transceiver
onsemi NCN26010 Industrial Ethernet Transceiver is a 10Mb/s, IEEE 802.3cg compliant device including a Media Access Controller (MAC), a PLCA Reconciliation Sublayer (RS), and a 10BASE-T1S PHY designed for industrial multi-drop Ethernet. The NCN26010 provides all physical layer functions needed to transmit and receive data over a single unshielded twisted pair. The onsemi NCN26010 Industrial Ethernet Transceiver communicates to host MCUs via the Open Alliance MACPHY SPI protocol. Applications include industrial automation, sensor interfacing, home/building control, and security/field instrumentation.
