Introduction to Ethernet PHY technology
Ethernet is an established, easy-to-use, reliable communications protocol. Industrial Ethernet enables effective implementation of Industry 4.0 and scales from factory floor to enterprise and beyond.
Robustness You Can Trust: Maximum system performance with industry compliance tested TI’s PHYs that are designed to support up to 125 C ambient temperatures and 16kV of ESD.
Real Time Communication: Bring time-sensitive networking (TSN) communication to your system with TI’s market leading low-latency and high determinism PHYs that are used in all major Ethernet fieldbuses.
Simplify Your Design Process: Accelerate your design & qualification time using Industry proven reference designs, which have passed compliance testing.
Featured products for Standard Ethernet
Increased automation is taking Ethernet to the edge. Industrial SPE enables connected edge nodes and distributed processing. Use single-pair Ethernet in your industrial design to move data over TCP/IP anywhere you need it.
Faster & Farther: Enable better system implementation with cable lengths up to 2km, and faster data delivery protocols using TI PHYs.
Minimize implementation cost: Reduce time and cost of upgrade by re-using more existing cabling infrastructure with TIs low noise receiver architecture.
Maximize System Uptime: Enable remote and predictive maintenance using TI’s proprietary runtime cable diagnostics toolkit. Stay ahead of cable degradation and decrease your system’s downtime.
