The 6-T pixel
To obtain the global shutter feature combined with a high sensitivity and good Parasitic Light Sensitivity (PLS), the pixel architecture
shown in
specifications as described in the
Frame Rate and Windowing
Frame Rate
The frame rate depends on the input clock, the Frame Overhead Time (FOT) and the Row Overhead Time (ROT). The frame period
is calculated as follows
Frame period = FOT + Nr. Lines * (ROT + Nr. Pixels * clock period)
Table 4. Frame Rate Parameters
Example: read out of the full resolution at nominal speed (80 MHz pixel rate = 12.5 ns, GRAN<1:0>=10):
Frame period = 7.8 μs + (480 * (400 ns + 12.5 ns * 640) = 4.039 ms => 247.6 fps.
In case the sensor operates in subsampling, the ROT is enlarged with 8 clock periods.
