MIPI A-PHY Aims to 15m Range, 48Gbps Speed

MIPI Alliance has initiated development of a physical layer (up to 15m distance) specification targeted for ADS, ADAS and other surround sensor applications. Initially, the standard supports 12-24 Gbps data rate, with work being under way to extend the speed up to 48 Gbps.

MIPI A-PHY v1.0 is expected to be available to developers in late 2019. It’s anticipated that the first vehicles using A-PHY components will be in production in 2024.

A-PHY v1.0 Features:
  • 12-24 Gbps speed
  • Asymmetric data link layer
  • Wiring, cost and weight optimization
  • High-speed data, control data and optional power share the same physical wiring
  • Point-to-point topology
  • Reuses generations of mobile protocols
  • Low EMI
  • Supports LiDAR, Radar and camera integration for autonomous driving

LED Flicker Tutorial Paper

IE 2008 publishes a paper " LED flicker: Root cause, impact and measurement for automotive imaging applications " by Brian Deegan, Valeo Vision Systems. " In recent years, the use of LED lighting has become widespread in the automotive environment, largely because of their high energy efficiency, reliability, and low maintenance costs. There has also been a concurrent increase in the use and complexity of automotive camera systems. To a large extent, LED lighting and automotive camera technology evolved separately and independently. As the use of both technologies has increased, it has become clear that LED lighting poses significant challenges for automotive imaging i.e. so-called "LED flicker". LED flicker is an artifact observed in digital imaging where an imaged light source appears to flicker, even though the light source appears constant to a human observer. This paper defines the root cause and manifestations of LED flicker. It defines the use cases wher...
