SPRUIM6A October 2018 – November 2020
The CSI-2 interface from the AM65x processor is terminated to two camera connectors to interface a CSI-2 standard camera:
The two connectors match the existing standards for camera cards. The CSI-2 connector on the board is selected based on the camera module installed. MCU_I2C0 and MCU_SPI0 are also connected to the camera connector through level translators.
The control signals connected to J39 are all 1.8 V, whereas the control signals connected to J22 can be either 1.8 V or 3.3 V. A jumper (J37) is used to select the required I/O voltage, as shown in Figure 3-20. Short Pin 1 and Pin 2 for 1.8-V I/O operation, or Short Pin 2 and Pin 3 for 3.3-V I/O operation. The footprint to mount the oscillator of part number KC2520B24.0000C1GE00 is provided to supply 24-MHz REFCLK to the CSI-2 module. Mount U114 for 1.8-V REFCLK, and mount U112 for 3.3-V REFCLK.
