Specification MIPI CSI-2 v2.0
Organization MIPI Alliance recently submitted the specification MIPI CSI-2 v2.0 — a new version of the widely used interface Camera Serial Interface (CSI-2). The new version expands the field of use of CSI-2 on the Internet of things, wearable electronics, medical devices, means of augmented and virtual reality, drones and cars.
Key improvements embodied in the MIPI CSI-2 v2.0, includes support for the color depth RAW-16 RAW-20, High Dynamic Range (HDR) and improved signal/noise. The number of virtual channels increased from 4 to 32, providing enhanced compatibility with image sensors with various data types, support for multiple exposures and other features required in driver assistance systems (ADAS). Support for Latency Reduction and Transport Efficiency (LRTE) improves aggregation capabilities without increasing the cost of the system; provides the capability of entering and processing in real time; optimizes the connections, allowing to reduce the number of conductors, and reduce power consumption. Support Differential Pulse Code Modulation (DPCM) 12-10-12 reduces bandwidth requirements, while allowing you to avoid the appearance of artifacts. In addition, the measures taken to improve electromagnetic compatibility and to increase the allowable length of the connections.
CSI-2 v2.0 can be implemented by means of one of the two physical layer interfaces, standardized MIPI Alliance: MIPI C-PHYSM, or MIPI D-PHYSM.
