1000BASE-T1 CMC Requirements

The potential scalability of Ethernet is an important motivation for car manufacturers to introduce Ethernet as an in-car networking technology. It is therefore essential that higher data rate Ethernet technologies are developed for automotive use. The OPEN Alliance is supporting the standardization of an Automotive Gigabit Ethernet standard through the work of TC3.

TC3 collected requirements and validated the technical proposals made available from the IEEE 802.3bp task force, leading to the release of the 1000BASE-T1 standard. For more information please visit:

Today TC3 defines 1000BASE-T1 magnetics characteristics and CMC limit lines for differential and mixed mode parameters, resulting in CMC performance and test specifications.
