NXP Semiconductors TJx1410 10Base-T1S PHY Transceivers
NXP Semiconductors TJx1410 10Base-T1S PHY Transceivers, including the automotive‑focused TJA1410 and the industrial‑focused TJF1410, provide compact, low‑power, and standards‑compliant connectivity solutions for single‑pair Ethernet networks. The TJA1410 is designed for automotive and industrial applications, offering strong EMC performance, ISO 26262 ASIL‑B functional safety compliance, and full adherence to IEEE 802.3cg and OPEN Alliance TC14 specifications. It communicates over a simple 3‑pin OA interface, supports both local and remote wake‑up via TC10‑TC14, and enables advanced diagnostics such as topology discovery. Packaged in a small HVSON8 (3mm × 3 mm) format, it delivers high signal quality and low quiescent current, making it suitable for applications such as body control modules, lighting, and zonal ECUs.
The NXP TJF1410 extends similar capabilities to industrial environments, also complying with IEEE 802.3cg and OPEN Alliance TC14 specifications while supporting TC10‑TC14 wake functions and advanced diagnostics like topology discovery. Designed for multidrop industrial Ethernet, it supports up to 32 nodes and cable lengths up to 100m, maintaining robust EMC performance and low power consumption. With a compact HVSON8 package and compatibility with Power‑over‑Data‑Line (PoDL), the TJF1410 is well‑suited for PLCs, motor drives, robotics, building automation, and other factory‑networking equipment.
