Maximum Line Rate for Region of Interest (ROI)

The sensor features the capability to define a Region of Interest to be readout on each 2K5 segment,

using bit 7 of register 0x01. Despite the fact this feature works for 4LS15K and 4LS10K, it was only

validated for 4LS5K. This ROI is defined by setting a Start Address (ROIStart) on register 0x19 and an

End Address (ROIEnd) on register 0x1A. The region of interest (number of readout pixels) is given by

the following equation:

Equation 9:

�� (��) = ((�� − ��) + 1) × (4 × ��)

With:

●

m = 1 for 1-To-1

●

m = 2 for 2-To-1

●

m = 4 for 4-To-1

The use of ROI presents some constrains that the user must respect:

●

ROIEnd address (register 0x1A) cannot be smaller than ROIStart address (register 0x19), however

it can be the same.

●

The ROI always reads a minimum size of 16 columns.

●

Each ROI address will generate a jump of 16 columns on readout. ROIStart and ROIEnd

addresses should be programmed between 0 and 160 (0xA0).

Equation 10:

�� = �� × 16

Equation 11:

�� = �� × 16 + 16

Equation 12:

�� = #�� × ��

With:

●

#LVDS = 4 for 1-To-1

●

#LVDS = 2 for 2-To-1

●

#LVDS = 1 for 4-To-1
