H_Period
Use the foillowing formula to calculate H_Period.
H_Period = MAX(Sensor_H_Period, Interface_H_Period, FPGA_H_Period)
Among Sensor_H_Period, Interface_H_Period, and FPGA_H_Period, the one with the
largest value is H_Period.
■
Sensor_H_Period
Sensor_H_Period is a fixed value for each PixelFormat regardless of the ROI size.
Please refer to the table below.

Interface_H_Period
Calculate the Interface_H_Period using the following formulas.
Interface_H_Period = (Width x PixelSize) / (AvailablePayloadBandwith x 1000)
Refer to the values in the table above for PixelSize.
[When the maximum packet length is 1476 bytes and the packet delay is 0 ns]
[When the maximum packet length is 8976 bytes and the packet delay is 0 ns]
■
FPGA_H_Period
Calculate the FPGA_H_Period using the following formulas.
FPGA_H_Period =( (Width + 8) ÷ 4 + 32 ) ÷ 111
The value of AvailablePayloadBandwidth varies depending on conditions such
as maximum packet length and packet delay.
