Video formats, modes and bandwidth
PIKE Technical Manual V5.1.2

As an example, VGA Mono8 @ 60 fps requires four lines (640 x 4 = 2560 pixels/
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 (at S400) is used. Thus one camera
can be connected to the bus at S400.
The same camera, run at S800 would require only 32% of the available band-
width, due to the doubled speed. Thus up to three cameras can be connected to
the bus at S800.
