Expanded CSI-2 Camera Spec Transcends Mobile Limits

The MIPI Alliance releases MIPI CSI-2SM v2.0, the next-generation of its Camera Serial Interface (CSI-2) specification. This version will allow designers to address imaging and vision needs for mobile, Internet of Things (IoT) devices, wearables, medical, augmented and virtual reality products, drones, and automotive systems. Enhancements of the spec include RAW-16 and RAW-20 color depth, expanded virtual channels from 4 to 32 to accommodate image sensors with multiple data types and support multi-exposure and multi-range sensor fusion for Advanced Driver Assistance Systems (ADAS) applications, Latency Reduction and Transport Efficiency (LRTE) for higher image-sensor aggregation without adding to system cost, Differential Pulse Code Modulation (DPCM) 12-10-12 compression, and scrambling to reduce Power Spectral Density (PSD) emissions, minimize radio interference, and allow further reach for longer channels. Version CSI-2 v2.0 can be implemented on either of two physical layers from MIPI Alliance: MIPI C-PHYSM and MIPI D-PHYSM. More information is available at https://mipi.org
