Figure 24: Reference Circuit Design for Rear Camera Interface
DVDD_1V2 is used to power the rear camera core, and VDD_AF_2V8 is used to power the rear camera
AF circuit. Both of them are powered by an external LDO.
3.19.2. Front Camera Interface
The front camera interface integrates a differential data interface meeting one-lane MIPI CSI standard,
and is tested to support 2MP cameras.
The pin definition of front camera interface is shown below.
