3. TECHNICAL BRIEF
The 5M Camera modules are connected to 34-pin main board and VGA Camera module is connected
to LCD FPCB with 20-pin Board to Board through 70 pin Board to Board connector.
VGA interface is dedicated camera interface port in DB3150, but 5 Mega camera is connected to
MMIC (Multi-media IC).
5 mega camera supply 24MHz master clock to camera module and receive 80MHz pixel clock(30fps),
vertical sync signal, horizontal sync signal, reset signal and 8bits YUV data from camera module. The
camera module is controlled by I2C port.
VGA camera port supply 24MHz master clock to camera module and receive 32.2MHz pixel
clock(15fps), vertical sync signal, horizontal sync signal, reset signal and 8bits YUV data from camera
module. The camera module is controlled by I2C port.
