7.3 MIPI*-CSI signal group specifications
7.3.1 JCAM1 and JCAM2 connector interface signals
Notes:
1. VCAM_IO is shared between JCAM1 and JCAM2
2. SID is used for setting I2C slave address on the second sensor in a two camera configuration
3. For a single camera configuration, lanes D0-D3 are paired with CLK0
4. For two camera configuration, lanes D0-D1 are paired with CLK0 and lanes D2-D3 are paired with CLK_2
5. Lanes D2 and D3 are optional and may not be needed if using a single low resolution camera
6. Voltage rails are programmable and can be configured in SW driver. However, the module design must be able to withstand voltages described in Table 11
(JCAM1, JCAM2 DC Supply info). Appropriate decoupling capacitors are required on the camera module side.
7. I2C signals require a 2.7k ohm pull-up to 1.8V
8. For two camera configuration, CAM_CLK is shared between both cameras
