TC 6 – Common Media Independent Interface Definitions for Automotive Purposes

The OPEN Alliance Technical Committee 6 (TC6) focuses on media independent communication interfaces (xMII) in order to improve their applicability for automotive networks. TC6 creates recommendations for automotive xMII standards and specifies xMII relevant enhancements. TC6’s objective is to develop the OPEN Alliance SGMII specification.

TC6 scope: 

  1. Select the parameters for connectivity between a IEEE 802.3-2018 compatible MAC and a physical entity (PHY)
  2. Select the parameters for connectivity between two IEEE 802.3-2018 compatible MACs
  3. Select the diagnostic and error handler features.
