Ethernet for Automotive Imaging Sensors call for interest

The following request for agenda time for a Ethernet for Automotive Imaging Sensors call for interest has been received from Kirsten Matheus and George Zimmerman. It will be discussed at the IEEE 802 LMSC July 2023 Plenary meeting in Berlin, Germany.

If you have any questions please get in touch with either or directly.

This is a call for interest to initiate a Study Group to develop a PAR and CSD for an electrical Ethernet physical layer and associated interface client specifications optimized for automotive imaging sensors. We believe there is a timely market opportunity for the introduction of such specialized interfaces now as the number of cameras per vehicle grows rapidly. The target automotive cameras stream multigigabit-speed data from the sensor and have low-utilization, intermittent control data in the other direction over the Ethernet link. While transmit and receive traffic flows are independent in traditional Ethernet, these new physical layers may benefit from additional control between the MAC and the PHY, e.g., at the Reconciliation Sublayer, to optimize the MAC/PHY interfacing and PHY power/complexity. These new physical layer applications operate under very tight power and cost/complexity constraints, creating the opportunity for new or modified IEEE 802.3 standards to better serve the application.

The call for interest will take place during the IEEE 802.3 Opening Plenary on the morning of Monday 10 July 2023. A call for interest consensus building meeting has been scheduled to occur from 19:30 to 21:00 CEST (17:30 to 19:00 UTC) on the evening of Tuesday 11 July 2023. The vote to determine if a Study Group will be formed will take place at the IEEE 802.3 Closing Plenary on the afternoon of Thursday 13 July 2023.
