2.7 Camera Serial Interface (MIPI CSI-2)
The Camera Serial Interface (CSI) from the Mobile Industry Processor Interface Alliance (MIPI) is
related to the MIPI DSI which is intended to be used for displays. The Verdin standard reserves up
to four lanes for the version CSI-2. This version interfaces use the MIPI D-PHY as physical layer
which is also used for the MIPI DSI interface on the Verdin module. As with the MIPI DSI, the first
data lane is bidirectional.
The MIPI CSI-2 supports different camera formats (e.g. RGB, YUV, YCbCr, RAW Bayer, etc.). Please
carefully check the datasheet of the Verdin module whether it supports the format of the camera.
Also, the maximum interface speed and supported camera resolution depends on the module.
