Pixel Clock

VA GigE camera provides a unique way to control the camera speed and frame rate. You can select the pixel
clock to operate the camera either in Normal or High-speed (over-clocked) mode. With Normal mode, the
camera's frame rate is determined by the CCD sensor manufacturer.
VA GigE camera internal design is optimized for High-speed mode. With High-speed mode, it is possible to over-
clock the camera which will result in higher frame rate. However, the camera signal to noise ratio (SNR) may be
reduced compared to Normal mode.
