NXP launches the first 10BASE-T1S PMD transceiver, delivering an scalable and cost-effective Ethernet connectivity solution for the smart edge
2026-03-05

The new PMD transceiver includes TJA1410 for automotive applications and TJF1410 for industrial control applications, helping OEMs extend low-cost multi-point Ethernet deployment to the network edge and providing critical support for building scalable software defined vehicles (SDVs) and industrial architectures.

Latest Updates

NXP Semiconductors N.V. (NASDAQ: NXPI) announced the launch of its first mass-produced 10BASE-T1S PMD transceiver series, including the TJA1410 for automotive applications and the TJF1410 for industrial control and building automation applications. These two devices mark a significant evolution in Ethernet technology, enabling OEMs to extend Ethernet coverage to the network edge and lay a unified and scalable network foundation for accelerating the transition to software defined architecture. They provide a robust Ethernet data path that combines the simplicity of the CAN bus and significantly reduces the system cost for large-scale deployment. Among them, TJA1410 has passed comprehensive certification for automotive functional safety related applications, and both devices comply with the latest Open Alliance TC14 specifications and have robust electromagnetic compatibility (EMC) performance.

This series of PMD transceivers divides the traditional Ethernet PHY into two parts. The digital part is integrated into the host MCU or switch, while the PMD part focuses on processing the basic analog functions required for signal transmission and reception on physical media. This design enables 10Mb Ethernet deployment to achieve lower system costs and has simplicity similar to CAN bus.

significant importance

As automotive and industrial control systems accelerate their evolution towards software defined architecture, OEMs urgently need a concise and cost-effective solution to extend Ethernet coverage to the network edge. TJA1410 and TJF1410 can provide reliable, compact, low pin count Ethernet deployment solutions with a convenient experience similar to CAN bus, thereby accelerating this transformation process. By deploying 10BASE-T1S technology at the edge, OEMs can easily implement various advanced features in the next generation of software defined cars, such as AI based sensor fusion and over the air updates (OTA). This multi-point, low-cost single pair Ethernet (SPE) solution helps reduce cabling, eliminate gateways, and unify edge devices into a universal Ethernet backbone architecture.

In the automotive field, this new device allows vehicle manufacturers to extend Ethernet to the body, comfort, and area architecture while meeting functional safety requirements. In the fields of industrial control and building automation, it has driven the migration from traditional fieldbus to secure and scalable end-to-end Ethernet networks.

Ritesh Saraf, Vice President and General Manager of the Ethernet Business Unit at NXP Semiconductors, said, "10BASE-T1S is a foundational technology that ultimately enables Ethernet to penetrate to end nodes - whether in automotive, industrial control, or building systems. With the new PMD transceiver, we have eliminated cost and complexity barriers, providing partners with a scalable path to extend Ethernet to the edge of their network. This new product release sets a new benchmark for deploying cost-effective and secure Ethernet connections in the next-generation software defined architecture. ”

More details

TJA1410 is designed specifically for automotive applications that require functional safety support, meeting ISO 26262 ASIL B level requirements, with robust EMC performance, extremely low static current, and support for remote wake-up function (compliant with OA TC10/TC14 standards) to achieve higher power efficiency. This device can be used in conjunction with a lower cost CAN FD common mode choke, thereby reducing the overall system cost of the 10BASE-T1S network.

Combining NXP's automotive MCU and switch products (which integrate 10BASE-T1S ports with MACsec security support, including S32K5, S32N7, and S32J100 series), the new PMD transceiver series can form a complete system level solution that supports end-to-end secure Ethernet communication. OEM can deploy scalable regional architectures and central computing architectures with built-in security and high reliability.

For industrial control and building automation applications, TJF1410 introduces the equally transformative PMD function, supporting the replacement of traditional fieldbuses such as Modbus or RS-485 with multi-point Ethernet. It brings advantages such as unified network, higher scalability, and secure communication across the entire system. This device also supports demanding industrial control applications, such as building circuit breakers, which far exceed the guidance specifications for PMD transceivers in the automotive Open Alliance TC14 standard in terms of node count and cable length.

When used in conjunction with the NXP MCX A microcontroller series, the TJF1410 can provide a comprehensive 10BASE-T1S system solution for industrial control and building automation applications, thereby optimizing system costs. The upcoming new members of the MCX A series will integrate a 10BASE-T1S port, which can be used in conjunction with TJF1410 to simplify system complexity and reduce bill of materials (BOM) costs.
