24 / 109 page  Dragster Functional description Datasheet • PUBLIC • Document Feedback DS000444 • v5-00 • 2025-Aug-29 24 / 109 / • The pixels 5 - 24 are normal pixels however, the photo diode is covered by a metal light shield. They serve as a dark reference. However, at longer wavelengths the metal shield will not completely shield light anymore. • The pixels 25 - 32 are electrical black pixels. In these pixels the photo diode is disconnected electrically from the readout chain. These pixels will follow all analogue and digital offset variations, however not integrate dark current or any photo current. They can be used check the validity of the dark pixels 5 - 24, or to compensate for line by line ADC offset variations. 7.1.1.2 DR-XK-3.5 Figure 8: Placement of pixels sensors with 3.5 µm pixel pitch (DR16K3.5) The first 64 pixels include not only dark pixels but also special pixels like described: • The output from the first & second pixels are directly connected to the pad 1 of the most left segments on top and bottom.3 • The output from the third and fourth pixels are directly connected to the pad 2 of the most left segments on top and bottom.2 • The fifth and sixth pixels are a black pixel, electrically fixed to ADC low saturation. • The seventh and eight pixels are white pixel, electrically fixed to ADC high saturation. • The pixels 9 - 48 are normal pixels however, the photo diode is covered by a metal light shield. They serve as a dark reference. However, at longer wavelengths the metal shield will not completely shield light any more. • The pixels 49 - 64 are electrical black pixels. In these pixels the photo diode is disconnected electrically from the readout chain. These pixels will follow all analogue and digital offset variations, however, not integrate dark current or any photo current. They can be used to check the validity of the dark pixels 9 - 48, or to compensate for line-by-line ADC offset variations. 3 These pixels are light sensitive. The respective outputs are connected to a test point on the headboard for debugging purpose in certain package variations. 1 ... 64 65 66 ... 4161 4162 ... 8257 8258 ... 12352 12353 ... 16447 16448 3.5 µm 3.5 µm Special Pixels Active Pixels |
