OmniPHY Highlights Automotive Ethernet Solutions


October 31, 2017

We all know that the connected car is one of the more interesting IoT applications today. But when we think about connected cars we often think about their relationship to external objects. However, there are many connected objects within the vehicles themselves.


And there are various connection types and protocols to link the different in-car controls, interfaces, and sensors. That’s not very efficient. In fact, it’s so inefficient that it’s made the wiring harness the third most expensive and heaviest component in cars today, following only the engine and the chassis.

So the connected car ecosystem has come together to standardize on what’s known as Automotive Ethernet. That provides a single connection for in-car communications. And it reduces costs, weight, and contributes to vehicles’ fuel economy in the process.

The IEEE Standards Association will be talking about Automative Ethernet this week at its Ethernet & IP @ Automotive Technology Day in San Jose. And OmniPHY Inc. will be there showing its automotive semiconductor IP solutions that leverage Automotive Ethernet technology.

The company explains that this technology supports 100 Mb over an unshielded twisted pair. And it adds that Automotive Ethernet enables vehicles to become autonomous servers with wheels.

OmniPHY’s Automotive Ethernet IP solutions include the:

• 100Base-T1 PHY IP,

• 1000Base-T1 PHY IP,

• Automotive Switch IP,

• Time-Sensitive Networking Controller IP, and

• Automotive-grade SGMII Interface IP.

The Ixia Automotive Ethernet BLACK BOOK explains that: “The move to Ethernet is happening quickly, as the competing technologies are proprietary and expensive. By 2015, multiple car manufacturers will use Ethernet for cameras (driver assist) and video (infotainment) connections. In this model, Ethernet is used in point-to-point links and is not yet being used as a shared medium for different interfaces (so a single link is only used for the connection to one video or camera).

“By 2020, automotive wiring harnesses will change from heterogeneous networks of proprietary protocols (such as CAN and MOST) to hierarchical homogenous automotive Ethernet networks,” Ixia continues. “In the new model, switched 1GE automotive Ethernet will interconnect all the domains in the car (meaning that Ethernet will be a shared medium with signals controlling throttle sharing the same twisted pair as a request to change the radio station and the video for the kids in the back seat).”
