Microchip Technology and AVIVA Links have announced a key milestone in automotive connectivity, successfully demonstrating interoperability between their respective ASA Motion Link (ASA-ML) chipsets. The achievement marks an important step toward the industry’s transition from proprietary serializer/deserializer (SerDes) solutions to open, interoperable standards developed by the Automotive SerDes Alliance (ASA).
ASA-ML, the first open standard defined by the alliance, enables asymmetric high-speed communication for in-vehicle networking. It connects multiple cameras, sensors, and displays that support Advanced Driver Assistance Systems (ADAS) and In-Vehicle Infotainment (IVI) applications.
The demonstration shows that ASA-ML chipsets from multiple semiconductor vendors can work together seamlessly, confirming the maturity and stability of the standard. According to Microchip, this interoperability provides automotive OEMs and Tier 1 suppliers with the confidence to design next-generation ADAS architectures based on an open, scalable, and secure connectivity framework.
Kevin So, Vice President of Microchip’s Communications Business Unit, said the collaboration “highlights the benefits of a multi-source, open standards approach” and reinforces the viability of the ASA-ML ecosystem.
AVIVA Links, which recently entered into a definitive agreement to be acquired by NXP Semiconductors, stated that the interoperability milestone will strengthen industry confidence in ASA-ML adoption. “Proving interoperability with Microchip’s ASA-ML SerDes chipset is an important milestone for the automotive industry,” said Kamal Dalmia, CEO of AVIVA Links.
Microchip was the first major semiconductor company to introduce an ASA-ML chipset through its acquisition of VSI Ltd. The company recently launched an ASA-ML camera development platform for the Japanese automotive market.
The ASA-ML standard supports asymmetric video, control, and data transmission at speeds of up to 16 Gbps. Its scalability and architectural flexibility make it suitable for higher levels of vehicle automation, such as ADAS Level 2 and above, where multiple high-resolution sensors and cameras are required.
The Automotive SerDes Alliance currently includes more than 175 members, including major OEMs such as BMW, Ford, GM, Hyundai-Kia, Nio, Renault/Ampere, Stellantis, Volvo, and Xiaopeng Motors. The alliance aims to promote a multi-vendor ecosystem that reduces supply chain risk, prevents vendor lock-in, and accelerates adoption of interoperable, high-speed connectivity standards.
Microchip’s VS7000 family of ASA-ML serializer/deserializer devices is available for sampling to qualified customers. The devices are designed for automotive, industrial, medical, and machine vision applications.
