As an example, VGA Mono8 @ 60 fps requires four lines (640 x 4 = 2560 pix-
els/byte) to transmit every 125 µs: this is a consequence of the sensor's line
time of about 30 µs, so that no data needs to be stored temporarily. It takes
120 cycles (120 x 125 µs = 15 ms) to transmit one frame, which arrives every
16.6 ms from the camera. Again no data need to be stored temporarily.
Thus around 64 % of the available bandwidth is used.
