The XGS 20000 (1. Gen) is a 20.25-megapixel M/C image sensor manufactured by On Semi. It delivers a 4500 × 4500 pixel array with a 3.2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 20.365 mm diagonal with a 0.042361111 aspect ratio, corresponding to the 1-inch optical class used in industrial and broadcast cameras. With 3.2 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
