1.12.1 Primary Camera Interface (CSI2-A/CSI21)
The primary camera interface (CSI2-A/CSI21) is compatible to the MIPI® Camera Serial Interface (CSI2)
specification and supports 4 data lanes.
The following table shows the location of the applicable interface signals of the primary camera interfaces on
the phyCORE-Connector.

Primary Camera Interface (CSI2-A/CSI21) Signal Location
Note:
Pins X1B5 to X1B8 on the phyCORE-Connector provide either signals of the keyboard interface, or camera
lanes 3 and 4 of the primary camera interface. The resistor array JN1 allows to choose which signals are
brought out at these pins. In order to use lanes 3 and 4 of the primary camera interface JN1 must be set to
position 2. Please refer to
Figure 6 to see where JN1 is located.
