Key phrase (70 chars max): NXP TJA1410/TJF1410: First 10BASE-T1S PMD transceivers for edge

NXP Semiconductors has announced the industry's first production-ready 10BASE-T1S Physical Medium Dependent (PMD) transceivers: TJA1410 for automotive and TJF1410 for industrial/building automation. These devices deliver scalable, low-cost 10 Mb/s single-pair Ethernet (SPE) in multidrop configurations to edge nodes like sensors and actuators.

Key Features and Architecture

The transceivers split the traditional Ethernet PHY: the digital part resides in an MCU or switch, while the analog front-end PMD handles transmit/receive over a standardized 3-pin OA interface. This reduces pin count, external components, and system complexity while maintaining full IEEE 802.3cg and Open Alliance TC14 compliance.

• Speed: 10 Mb/s multidrop Ethernet
• Cable length: Up to 100 m
• Nodes supported: Up to 32 on a single bus (TJF1410)
• Package: Compact 3 mm × 3 mm HVSON8
• Compliance: IEEE 802.3cg, OA TC14 (topology discovery, TC10/TC14 wake-up)

Automotive-Specific Advantages (TJA1410)

• ISO 26262 ASIL B functional safety compliant
• AEC-Q100 Grade 1 qualified
• Supports remote wake-up over data line (no extra wiring)
• Robust EMC with low-cost CAN FD common-mode chokes

Industrial Advantages (TJF1410)

• Optimized low quiescent current in power-down mode
• Power-over-data line compatibility
• Suitable for zonal/centralized architectures

Target Applications

These transceivers enable Ethernet connectivity at the lowest edge levels in software-defined vehicles (SDV), industrial automation, building management, and edge networks-replacing legacy fieldbuses while keeping IP-based communication, security, and scalability.

Already in production, customer integrations are advancing for next-gen platforms requiring cost-effective, unified Ethernet backbones.
