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
DP83826E ACTIVE Low latency 10/100-Mbps PHY with MII interface and enhanced mode
DP83822IF ACTIVE Low-power, robust 10/100-Mbps Ethernet PHY transceiver with fiber support & 16-kV ESD
DP83869HM ACTIVE Extended temperature, high-immunity gigabit Ethernet PHY transceiver with copper & fiber interface

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.
