NAV Alliance welcomes the participation of individuals from Promoter and Contributor companies in both technical and marketing activities. Below is a short overview of NAV Alliance’s new working groups. If you are a member and would like to sign up to participate in a working group, please click here!
Scope: This project is to create Physical Layer specifications and Management Parameters for 25Gbps and 50Gbps electrical interfaces for automotive Ethernet networks.
Chairman: Ramin Farjad, Marvell
— Define a 25Gbps PHY over a single shielded TBD copper cable with length up to TBD and up to TBD in-line connectors in automotive environment
— Define a 50Gbps PHY over a TBD shielded TBD copper cable with length up to TBD and up to TBD in-line connectors in automotive environment
— Support the Ethernet frame format utilizing the Ethernet MAC
— Support data rates of 25G and 50G with BER<1E-12 at the MAC/PLS interface
— Support full-duplex operation with symmetric data rates (max data rate in both directions) as well as asymmetric data rates (max data rate in one direction and lower data rate in the opposite direction)
Scope: Specification of the EMC requirements and limits for communication channels between two Ethernet Ports (inclusive the PHY) at at speeds higher than 10Gbps.
Start Date: End of 2019
Chairman: Jundi Ramzi, VW Group
— Communication channel supports automotive environment – Temperature, Cables & Connectors
— Phy and interface (MDI to connector)
— Specification of the failure criteria’s
— Specification of test setup
— Specification of the levels, limits and test methods
Scope: This project is to specify the integration of an Automotive Multi-Gig PHY in an Automotive Electronic Control unit (ECU) or an Electronic Vehicle Computer (EVC).
Chairman: Olaf Grau, Bosch
— Specify and dimensioning automotive power supply applications for Automotive Multi – Gig PHYs
— Specify PCB design rules that cover the needed signal integrity for Automotive Multi-Gig PHYs
— Proposal of additional PCB placed components needed for Automotive Multi-Gig operation
— Specify diagnosis for an Automotive Multi-Gig link segment
— Define power dissipation handling for automotive Multi-Gig components
— Define host CPU interconnection for Automotive Multi-Gig PHYs
Scope: This WG defines standard encapsulation of various protocols within Ethernet frames in a backwards compatible manner. The initial target protocols for encapsulation are I2C, SPI, Various Camera Interfaces, and for example Radar, Lidar applications.
Start Date: May 2019
Chairman: Mrudula Kanuri, Nvidia
— Backwards compatibility with the existing Ethernet Frame formats
— Extensibility and adaptability with new or developing protocols
— Will not define encapsulation where other relevant standards exist
Scope: This WG defines how to interface the IVN (In-Vehicle Network) components and its features with respect to manageability. Therefore, it identifies recommendations associated with hardware and software-based interfaces that are supporting systems used for autonomous vehicles. The WG elaborates also on an automotive network management protocol that includes additional considerations including enhanced diagnosis, predictive maintenance, redundancy, Quality of Service, wake-up and sleep and device management.
Chairman: Helge Zinner, Continental
— Identification of IVN key features for autonomous vehicle systems
— IVN Interface (SW, Protocol) definition
— Definition of an automotive management protocol
Team up with industry leaders to define the future of automotive networking.
