Gpixel announces the pin-compatible GMAX3405 and GMAX3412 CMOS image sensors – both based on a high-performance 3.4 µm charge domain global shutter pixel to complete its c-mount range of GMAX products. With options for read out via either LVDS or MIPI channels, these new sensors are optimized for easy integration into cost-sensitive applications in machine vision, industrial bar code reading, logistics, and traffic.
GMAX3405 provides a 2448(H) x 2048(V), 5 MP resolution in a 2/3” optical format. In 10-bit mode, reading out through all 12 pairs of LVDS channels, the frame rate is over 164 fps. In 12-bit mode, 100 fps can be achieved. Using the 4 MIPI D-PHY channels, the maximum frame rate is 73 fps with a 12-bit depth. GMAX3412 provides a 4096(H) x 3072(V), 12 MP resolution in a 1.1” optical format. In 10-bit mode, reading out through all 16 pairs of LVDS channels, the frame rate is over 128 fps. In 12-bit mode, 60 fps can be achieved. Using the 4 MIPI D-PHY channels, the maximum frame rate is 30 fps with a 12-bit depth. In both sensors, various multiplexing options are available for both LVDS and MIPI readout to reduce the number of lanes.
The 3.4 µm charge-domain global shutter pixel achieves a full well capacity of 10 ke- and noise of 3.6 e- at default x1 PGA gain, down to 1.5 e- at max gain setting (x16), delivering up to 68.8 dB linear dynamic range. The advanced pixel design and Red Fox technology combined brings a peak QE of 75% @ 540 nm, a NIR QE of 33% @850 nm , a Parasitic Light Sensitivity of -88 dB and an excellent angular response of > 15° @ 80% response. All of this combined with multislope HDR mode and ultra-short exposure time modes down to 1 us.
“The GMAX family was originally known for the world’s first 2.5 µm global shutter pixel. As the product family grows, we are leveraging the advanced technology that makes the 2.5 µm pixel possible to bring more generous light sensitivity with larger pixel sizes fitting mainstream optical formats. With the addition of the MIPI interface and pin-compatibility and excellent NIR response, these 2 new models bring more flexibility and cost-effectiveness to the GMAX product family.” says Wim Wuyts, Gpixel’s Chief Commercial Officer.
Both GMAX3405 and GMAX3412 are housed in 176 pin ceramic LGA packages, both being pin-compatible to each other. The outer dimensions of the 5MP and 12MP sensors respectively are 17.60 mm x 15.80 mm and 22.93 mm x 19.39 mm. The LGA pad pattern is optimized for reliable solder connections and the sensor assembly includes a double-sided AR coated cover glass lid.
