The Automotive SerDes Alliance is a non-profit industry alliance of automotive technology providers collaborating to encourage standardizing of asymmetric SerDes technology:
Member companies of the leading industry alliance cover the entire breadth of automotive ecosystem including car manufacturers (OEMs), tier-ones, semiconductor suppliers, cable & component manufacturers and test houses & testing tool vendors. Having such a diverse and rich ecosystem ensures that the ASA standards are in-tune with market requirements and are optimized through the participation of industry experts.
The group was established in 2019 by BMW, Continental, Broadcom, Fraunhofer IIS and NXP as founding members. In the short amount of time since its inception, ASA has been growing rapidly and now has more than 90 active member companies. In December 2020, ASA released the “ASA Motion Link” transceiver specification v1.01, which defines a SerDes communication technology for in-vehicle connectivity ranging from 2Gbps to 16Gbps line rate. The member companies are currently finalizing v1.1 of the specification.
