BEGIN ARTICLE PREVIEW:

The A-PHY v1.0 specification provides an asymmetric data link in a point-to-point topology, providing high-speed unidirectional data, embedded bidirectional control data and optional power delivery over a single cable. It features an ultra-low packet error rate of 10-19 which translates into particularly reliable data connections.At the same time, it offers a high immunity to EMC effects in the notoriously demanding automotive environments. Its reach up to 15 meters should cover the very most automotive requirements even at data rates of up to 16 Gbps; the roadmap provides for further development of up to 48 Gbps. Version 1.1 which is already under development will double the data rate to 32 Gbps and increase the uplink data rate to 200 Mbps.At the same time, the MIPI Alliance introduced MIPI Automotive SerDes Solutions (MASS).  MASS will provide automotive OEMs and suppliers with end-to-end high-performance connectivity solutions for the growing number of cameras, sensors and displays that enable automotive applications such as advanced driver-assistance systems (ADAS), connected in-vehicle infotainment (IVI) and, ultimately, fully autonomous vehicles. These solutions, with focus on even higher functional safety and security built in at the protocol level, will help automakers integrate new and emerging safety features such as low-latency backup cameras, lane-keeping and …
