3. TECHNICAL BRIEF
The Camera module is connected to LCD FPCB with 20pin Board to Board connector (AXK720147).
Its interface is dedicated camera interface port in MSM6280. The camera port supply 12MHz master
clock to camera module and receive 24MHz pixel clock (15fps), vertical sync signal, horizontal sync
signal, reset signal and 8bits data from camera module. The camera module is controlled by I2C port
from MSM6280.
