2.5.3 Camera Interfaces [J52_CP]

The EVM includes 40-pin (2x20, 0.5-mm pitch) high speed connectors [J52] for connecting with cameras and other image capture devices. This expansion connector can support up to two CSI2 interfaces. The bandwidth of each CSI2 interface is 10Gbps (4 data lanes each up to 2.5Gbps). The expansion connector also includes power and other IO for communicating with the capture devices. All control signals are configurable for 3.3-V or 1.8-V IO voltage levels. See Section 2.3.1 for configuration details.
