The results were obtained using 625 nm, 530 nm, and 470 nm illumination for the red, green and blue lines,

respectively. The ADC ramp gain was adjusted to the equivalent of 1 V swing, for 12-bit ADC mode at 60 MHz (MCLK).

The sensors temperature was approximately 60 ºC (uncontrolled temperature environment). The values presented are

for the default configuration of Full Well around 20 ke- (STS3 Register bits [3:0] = 0x0). Sensor supply levels were the

typical ones: VDDA = 3.3 V and VDDD = 1.8 V. The set Readout mode was 1-To-1. DSNU and PRNU results were

characterized for each variant. The remaining parameters are valid for all variants, once they all share the same silicon.

The settings used to get these values are those recommended by the European Machine Vision Association standard

1288 from the Machine Vision Sensors and Cameras. https://www.emva.org/standards-technology/emva-1288/
