2.4.5 Camera Interface 40-Pin High Speed [J20]

The EVM includes a 40-pin (2x20, 2.54 mm pitch) high speed camera interface [J20]. The expansion connector supports two CSI-2 (4 Lanes each), power, and control signals (I2C, GPIO, and so forth): All control signals are configurable for 3.3 V or 1.8 V voltage levels.
