New single-pair Ethernet PHY extends reach of factory and building automation applications

01/01/2021

Texas Instruments (TI) introduced a new Ethernet physical layer (PHY) capable of transmitting 10-Mbps Ethernet signals up to 1.7 km through a single pair of twisted wires. This additional cable length helps designers extend the reach of industrial communications without increasing system weight or cabling costs.

The DP83TD510E helps designers implement a single communications network, from controller to edge node, that is capable of transmitting full-duplex data over a single pair of twisted wires. By eliminating the need for additional protocols, gateways and cables for higher-bandwidth communications, designers can simplify network management while improving system control and interoperability in long-distance applications including HVAC valve and actuator control, field transmitters, elevator main controls and fire alarm control panels.
