TC9 – Automotive Ethernet Channel & Components

TC9 aims to define electrical requirements and test procedures for the cabling channel and associated components, including connectors, cables, and cable assemblies. This specification aligns with the link segment requirements outlined in IEEE 802.3 automotive Ethernet standards across different speed grades. By doing so, TC9 ensures consistency, providing a standardized framework for test methodology and component definitions.

The scope of TC9 includes the following topics:

  • Link segments for automotive Ethernet standards according to IEEE 802.3 on electrical media
  • Cables and cable assemblies
  • Cable connectors and board connectors including termination process related items
  • EMC environment in the wiring harness
  • Electrical requirements
  • Measurement setup and test procedures for electrical and EMC parameters of link segment and cabling components

Committee Goals

The primary goal of TC9 is the definition of component requirements for automotive Ethernet link segments according to IEEE 802.3 standards. The work of the committee comprises all speed grades on electrical media. Related measurement procedures are developed with a generic approach to ensure that the test methodologies can also be used for qualification of cabling components for other communication protocols in road-vehicle applications.

The current focus of the committee’s work is the channel and component specification for 10BASE-T1S which is planned for publication in 2024. The work on the specification for 25GBASE-T1 cabling components is planned to be started in 2024.
