2.6.1 Camera Interface, 22-Pin Flex

The EVM supports four 22-pin flex (0.5mm pitch) connectors [J1][J2] [J33] [J34] for interfacing with camera modules. Each camera interface provides MIPI CSI-2 interface (4 lanes), clock or control signals, and power (3.3V) to the camera. The camera interfaces are shared/multiplexed between the 22-pin flex connectors and the 40-pin high speed expansion. See Section 2.7.4 for details on selection control.

To enable identical camera modules to be used simultaneously, I2C mux is used to select each camera (TCA9543). The voltage level for Clock/Control signals is selectable between 1.8V and 3.3V. See Section 2.7.4 for details.
