4.6.2 MIPI Camera Interface
The SLM550 module supports the MIPI interface Camera and provides a dedicated camera power
supply. The main camera is a CSI1 interface that supports four sets of data lines and can support up to
13M pixels. The front camera is a CSI0 interface that supports four sets of data lines and can support
5M pixels. The module provides the power required by the Camera, including AVDD-2.8V,IOVDD-
1.8V,AFVDD-2.8V (powered by the focus motor) and D-VDD1.2V (CAM core voltage). D-
VDD1.2V(CAM core Voltage) Ask the customer to add an external circuit.
