3. Technical brief
Table 3-2-1. Interface between Main board and 3M camera (in Main)
Table 3-2-2. Interface between VGA Camera Module and FPCB (in Upper FPCB)
The 3M Camera modules are connected to 24-pin main board and VGA Camera module is connected
to Upper FPCB with 20-pin Board to Board through 60 pin Board to Board connector.
Its interface is dedicated camera interface port in DB3150. The camera port supply 24MHz master
clock to camera module and receive 10MHz pixel clock(15fps) for 3M camera, 12MHZ pixel clo
ck(15fps) for VGA camera, vertical sync signal, horizontal sync signal, reset signal and 8bits YUV
data from camera module. The camera module is controlled by I2C port.
