Common xMII Interface Definition

The focus of TC6 is to improve the applicability of existing xMII standards for Ethernet-based automotive networks with data rates of 100 Mbit/s and 1 Gbit/s. Moving towards standardized xMII specifications for the automotive industry is an important factor for the successful introduction of Ethernet into automotive networks. It will ensure product reliability and interoperability as well as reduce development time and costs. 
 
The objective is to capture relevant automotive requirements covering technical interface topics related to physical signaling, interface logic, timing, interface speed, EMC, temperature, robustness, interoperability, energy saving and costs. Within the work packages the group analyses existing xMII standards to identify gaps and incompatibilities in regards to automotive networks. 

TC6 creates a recommendation for preferred automotive xMII standards. The document specifies relevant interface enhancements covering automotive requirements.
