3. TECHNICAL DESCRIPTION
Table 3-2-1. Interface between Main board and 5M camera (in Main)
Table 3-2-2. Interface between VGA Camera FPCB and main board.
The 5M Camera modules are connected to 24-pin main board and VGA Camera module
is mounted to VGA FPCB and VGA FPCB is connected to 34-pin main board.
Its interface is dedicated camera interface port in DB3200. The camera port supply 24MHz master
clock to 5M ISP and 12Mhz Master clock to VGA module and receive 48MHz pixel clock(15fps) for ISP
and 9.5Mhz pixel clock(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.
