The maximum USB bandwidth is;
[USB Limit] = 5120 x 3840 x 8bit x 16.00 fps = 2516582400 bps
(1) IF V-Binning Off
The data rate by ROIsettingis,
[USB Rate] = [Width] x [Height] x 8 ÷ ((([Height] x 641) + 38580) ÷ 40MHz)
x 1.25
As comparing [USB Limit] and [USB Rate],
a) IF [USB Limit] < [USB Rate],
[Output Rate] = [USB Limit] ÷ [Width] ÷ [Height] ÷ 8 ÷ 1.25
b) IF [USB Limit] > [USB Rate]
[Output Rate] = 1/((([Height] x 641) + 38580) ÷ 40MHz)
[Trigger Period] = (2/ ([Output Rate])+[Exposure Time:10us ~8s]) + 130us
+ 16.025 us
(2) IF V-Binning On
The Data Rate by ROI setting is;
[USB Rate] = [Width] x [Height] x 8 ÷ ((([Height] x 1282) + 38580) ÷
40MHz) x 1.25
As comparing [USB Limit] and [USB Rate],
a) IF [USB Limit] < [USB Rate],
[Trigger Rate] = [USB Limit] ÷ [Width] ÷ ([Height] x 2) ÷ 8 ÷ 1.25
b) IF [USB Limit] > [USB Rate],
[Output Rate] = 1/((([Height] x 1282) + 38580) ÷ 40MHz)
[Trigger Period] = (2/ ([Output Rate])+[Exposure Time:10us ~8s]) + 130us
+ 32.050 us
