TJA1103 Ethernet PHY
NXP's Ethernet PHY offers advanced diagnostics and leading-edge power consumption
NXP's TJA1103 is the third-generation product of NXP’s successful family of 100BASE-T1 automotive Ethernet PHYs. It is perfectly suited to support the rapid expansion of Ethernet to the edge of the network or provide a robust connection to domain controllers in the center of the car. The TJA1103 complies with all state-of-the-art conformance test specifications and is designed according to ISO 26262 to meet ASIL B, providing enhanced monitoring and diagnostic features.
The TJA1103EVB evaluation board is a low-cost hardware development tool that supports the functional evaluation of the 100BASE-T1 Ethernet PHY TJA1103. To flexibly adapt to different application use cases, all configuration options can be selected via jumpers and all logic interfaces can be accessed via pin headers.
For users who need to evaluate the xMII datapath in an application context together with NXP processors, the TJA1103SDB SABRE development board is specifically designed for software engineering tasks. To enable quick application prototyping, various NXP system development boards feature the common SABRE connector. For example, the S32K3, S32G, and i.MX 8 processors.
