IEEE 802.3cg Compliant Ethernet Transceiver Includes Media Access Controller and PLCA Reconciliation Sublayer Designed for Industrial Multi−Drop Ethernet
onsemi has introduced a new IEEE 802.3cg compliant Ethernet Transceiver that includes a Media Access Controller (MAC), a PLCA Reconciliation Sublayer (RS), and a 10BASE−T1S PHY and is designed for industrial multi−drop Ethernet. The newNCN26010 transceiverprovides all physical layer functions needed to transmit and receive data over a single unshielded twisted pair and communicates to host MCUs via Open Alliance MACPHY SPI protocol. This new device is suitable for industrial automation, sensor, and control interfacing, home/building control, and security and field instrumentation.
The NCN26010 exceeds the noise immunity levels specified in IEEE 802.3cg to enable 50+ meters of range, providing robust signal detection in noisy industrial environments. It offers the lowest line capacitance to support five times the node requirement of the IEEE 802.3cg standard, supporting up to 40 nodes on a 25-meter segment and maximizing the cost savings of wiring and installation provided by 10BASE-T1S solutions.
