3. TECHNICAL BRIEF
The 2M Camera modules are connected to 24-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.
These two cameras are dedicated camera interface ports in DB3200.
2 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.
