3. TECHNICAL BRIEF

The VGA Camera module is connected to socket type connector with 20 pin (CLE9120-2761E). Its interface is dedicated camera interface port in MSM6245. The camera port supply 24.576MHz master clock to camera module and receive 12.288MHz 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 MSM6245.
