ASA Motion Link Enables Secure Automotive Display Connectivity

Microchip and Marelli Demonstrate Standardized Automotive Video Connectivity

On September 3, Marelli and Chandler, Arizona-based Microchip Technology announced a new solution that streams graphics and video from a vehicle’s centralized computer directly to automotive displays using ASA Motion Link (ASA-ML), an open standard for automotive video connectivity. The joint demonstrator is designed to simplify display architectures, reduce system costs, and increase sourcing flexibility as automakers transition toward software-defined vehicles. By moving centrally generated content across a standardized connectivity architecture, the solution addresses the growing need for efficient communication between centralized computing systems and vehicle displays.

ASA-ML Provides an Interoperable Alternative to Proprietary Technologies

Developed by the Automotive SerDes Alliance (ASA), ASA-ML enables secure, high-speed video and graphics transmission across products from multiple technology providers. This creates an interoperable alternative to proprietary technologies and can give automakers greater flexibility when selecting components for future vehicle architectures. The approach is particularly relevant as software-defined vehicles increase the role of centralized computing and require vehicle systems to exchange increasingly complex graphics, video, and interface data. The standardized link is intended to support this transition while helping simplify the underlying display connectivity architecture.

Microchip and Marelli Integrate the Display Connectivity Solution

Microchip’s VS7000 ASA-ML chipset processes and transmits centrally generated content over a standardized high-speed link. Marelli enables display-side integration by configuring and optimizing the ASA-ML deserializer to decode video streams directly at the display. This division of functionality allows the centralized computer to generate and transmit content while the display-side system receives and decodes the video stream. The joint demonstrator therefore combines Microchip’s transmission technology with Marelli’s display integration capabilities to demonstrate an end-to-end implementation based on the ASA-ML standard.

Support for Displays, Cameras, Navigation and Infotainment

The solution supports applications including camera feeds, navigation, infotainment, and vehicle interfaces, making the connectivity approach applicable to several display-related functions within modern vehicles. Key capabilities include integrated authentication and encryption, lossless transmission, electromagnetic-noise immunity, data rates of up to 16 Gbps, and improved power efficiency. These characteristics are intended to provide secure and reliable high-speed transmission while addressing practical automotive requirements. Microchip Technology provides the VS7000 chipset for processing and transmission, while Marelli handles display-side deserializer configuration and optimization.
