Camera interface

The device uses a Mirage- X camera module. Mirage-X is a 1.3Mpixel camera with sensor resolution of 1280 x

960. The following figure shows the block diagram where CCP bus is used to transfer image data from camera

to engine. Bi-directional control bus is an SW implemented I2C interface.

Camera regulator N1470 powers digital parts of camera. VAUX power rail is for powering analogue parts of the

camera.

CAMVCTRL signal (Vctrl) is used for activating the camera module. When Vctrl is turned on High level , the camera

module enters the operation mode. When Vctrl is turned on Low level, the camera module enters the power

off mode.

CAMCLK signal feeds system clock for camera module.
