3. TECHNICAL BRIEF
The VGA Camera module is connected to LCD FPCB with 20pin Board to Board connector
(AXK720147G). Its interface is dedicated camera interface port in MSM6280. The VGA camera port
supply 24.576MHz master clock to camera module and receive 24.576MHz pixel clock (30fps), vertical
sync signal, horizontal sync signal, reset signal and 8bits data from camera module. The VGA camera
module is controlled by I2C port from MSM6280.
