NXP Semiconductors has introduced what it says are the first production‑ready 10BASE‑T1S Physical Medium Dependent (PMD) transceivers, launching the TJA1410 for Automotive applications and the TJF1410 for industrial and building automation.

The devices are designed to extend Ethernet connectivity to the network edge, supporting the shift towards software‑defined architectures.

The transceivers separate a traditional Ethernet PHY into digital and analogue elements, enabling the digital layer to be integrated into a host microcontroller or switch while the PMD manages analogue signalling. NXP says this helps reduce system cost and delivers a CAN‑like operating experience for 10 Mbit/s Ethernet links.

“With our new PMD transceivers, we remove cost and complexity barriers and give our partners a scalable path to extend Ethernet all the way to the edge of their networks,” sAId Ritesh Saraf, Vice President and General Manager for Ethernet at NXP. “10BASE‑T1S is a foundational technology that finally makes Ethernet viable all the way to the end‑node.”

The automotive‑grade TJA1410 meets ISO 26262 ASIL B requirements and supports features such as low quiescent current, remote wake capabilities and robust EMC performance. It also works with lower‑cost CAN FD common‑mode chokes. Paired with NXP’s automotive microcontrollers and switches, the device forms part of an end‑to‑end secured Ethernet solution for zonal and central compute architectures.

For industrial and building automation, the TJF1410 enables migration from legacy fieldbuses like Modbus or RS‑485 to multi‑drop Single Pair Ethernet, supporting large node counts and extended cabling. When combined with NXP’s MCX A-series microcontrollers, it offers a complete 10BASE‑T1S platform aimed at reducing system complexity and cost.
