The MIPI CSI-2 (Camera Serial Interface) specification is celebrating its tenth birthday these days and the party is quite big with millions of mobile devices out there, passing every pixel from the camera sensor to the application processor through this interface.
The success of this protocol is due to a very robust architecture that enables high-speed traffic with low power consumption and cost-effective implementation. The CSI-2 protocol has been enhanced several times during the last decade and these days the MIPI Camera working group is working on a new enhanced version, CSI-2 2.0, to address the ever-growing requirements.
First, let’s review the ‘Why?’—What are the driving factors that lead CSI-2 protocol enhancements?
