CTOnews.com February 14 news, Changguang Chen core officially announced the launch of a small array global shutter CMOS image sensor-GMAX4002 high-speed version. Compared with the standard version, GMAX4002 high-speed version is more widely used in machine vision, industrial inspection, 3D imaging, motion capture and other high-speed dynamic scenes.

The GMAX4002 high-speed version uses 4um charge-domain global shutter pixels and a 1.7" optical size with an effective resolution of 2048 (H) x 1200 (V). With the combination of on-chip microlens array and optical tube technology, the chip has excellent shutter efficiency and angle response. The high-speed version maintains a peak QE of 72% in the 550 nm band, while with advanced near infrared enhancement technology (Red Fox), the QE can reach 37% in the 850 nm band, ensuring that the chip has a high sensitivity in the near infrared band. The GMAX4002 high-speed version has a full well capacity of 10.8 keto and a readout noise of less than 2.9e -, and the dynamic range is larger than 64dB.

CTOnews.com learned that the GMAX4002 high-speed version supports eight pairs of sub-LVDS interfaces. In 10bit ADC output mode, the maximum data rate of a single channel is increased by 50% (from 800 Mbps to 1200 Mbps), and the highest frame rate at full resolution is increased from 229 fps to 344 fps. At the same time, the GMAX4002 Express Edition supports the on-chip 2 x 2 binning function, which can further increase the frame rate to 660 fps depending on the specific application scenario.

The GMAX4002 high-speed version is pin-compatible with the standard version and is packaged in 74-pin CLCC with the same package size (16.6mm x 12.9 mm) and is available in Bayer color and black and white.

At present, the GMAX4002 high-speed version of the engineering sample is now available for pre-order, and the evaluation board can be provided at the same time, and shipment is expected to begin in March 2023.
