Modern automotive applications require vast amounts of data to be moved within the vehicles. Applications such as autonomous driving require uncompressed video data to be transported from cameras and sensors located throughout the vehicle to processing units. The amount of data is being increased further as both the resolution and the number of cameras and sensors continually increase. Similarly, high bandwidth video data needs to be transported from processing units to high resolution displays that are now becoming pervasive in advance vehicles. A data transport system typically comprises of a physical layer device that is responsible for moving the bits on the wire and “upper layers” that are responsible for delivery of data as logical units. This paper discusses the Time Division Duplex (TDD) approach adopted by Automotive SerDes Alliance (ASA) for the physical layer implementation of such links and the use of the TDD PHY in protocols such as Ethernet to provide an overall solution for the automotive needs.
