SAN JOSE, Calif. – October 16, 2024 – AVIVA Links, Inc., the automotive company delivering the world’s most advanced multi-Gigabit vehicle infrastructure for ADAS and camera systems, today announced a live demo at Ethernet & IP @ Automotive Technology Day 2024 showcasing AVIVA’s breakthrough connectivity solutions that enable next generation vehicle architectures. AVIVA’s asymmetrical Ethernet devices based on the ASA-MLE standard pave the path for true zonal aggregation by providing the industry’s only single-chip solution that combines ASA Motion Link Video and Ethernet backbone in a seamless and cost-effective manner.
The automotive industry is rapidly moving from legacy domain controller-based architecture to centralized compute architecture, accompanied by a transition from point-to-point (P2P) topologies to zonal topologies. OEMs want to combine high-speed video from multiple sensors in a physical zone with low-speed CAN, LIN and Ethernet data to maximize the use of the zonal gateway, while minimizing the length, weight and cost of the cabling from these zones. However, on platforms today, the high-speed video links have remained separate from the Ethernet in-vehicle network, due to the lower speeds, higher power and costs associated with the traditional Ethernet solutions.
“This is a watershed moment for the automotive industry that breaks down the inflexible silos created by proprietary SerDes solutions and ushers in a new generation of vehicles,” said Kamal Dalmia, CEO and co-founder at AVIVA. “Customers will be able to combine the high-speed video links and the Ethernet backbone with a single chip solution and can achieve this dynamic configurability with no changes to the hardware. This flexibility will enable a new generation of vehicles with capabilities the industry has long desired, and it’s now a reality as we demonstrate the achievement live this coming week.”
AVIVA’s family of asymmetrical Ethernet devices based on the ASA-MLE standard provide a low power, cost efficient and ultra-high-speed solution for addressing the video links. In addition, by supporting Ethernet protocol natively, it also enables OEMs to combine lower speed Ethernet data with the high-speed video links in a seamless manner. Each ASA port on AVIVA devices can be configured to work in either ASA-ML (SerDes) mode or ASA-MLE (Ethernet) mode, and both the ASA and Ethernet ports can work as either inputs or outputs. These unique features give OEMs complete flexibility to dynamically configure the various links in the automotive network, enabling true zonal architectures and video sharing across ECUs and Controller Domains.
This AVIVA family of asymmetrical Ethernet devices also enable significant reduction in complexity, weight (several kilograms) and cost of the wiring harnesses, while delivering advanced system level features such as time-stamp based precise synchronization and state-of-the-art security.
Details on the Demo
AVIVA’s demonstration incorporates a first of its kind camera/ethernet communication subsystem featuring zonal aggregation based on the Automotive Serdes Alliance Motion Link (ASA-ML and ASA-MLE) technologies. High-speed video streams from multiple automotive sensors are aggregated with data from an Ethernet source onto a single ASA link. The aggregated video/ethernet data are then sent over an automotive grade cable to a de-aggregator board where these streams are separated. The video streams are then sent through the MIPI ports to a SoC for display on a monitor, while the Ethernet data is sent to a laptop/PC for display/capture.
