CMOSIS has recently launched a 20-MP image sensor for the most challenging industrial applications. The newly-added CMV20000 enables CMOSIS to expand its CMV global shutter CMOS image sensor family.
The CMV20000 image sensor consists of a 20 MP (5,120x3,840) resolution with 6.4 um-sized square pixels that enable an active sensor area of 32.8x24.6 mm, equal to 35 mm film optical format. Up to 45% peak quantum efficiency can be attained that leads to excellent responsivity of 8.29 V/lux.s, along with 66 dB of convenient dynamic range. The patented 8-transistor px cell architecture uses correlated double sampling in global shutter mode to lower dark noise and sensor matrix’s FPN non-uniformity. The sensor ensures maximum shutter efficiency.
With a 12-bit ADC resolution, the CMV20000 ensures 30 full fps at full 20 MP of resolution. 16 LVDS outputs, each running at 480 Mbit/s, facilitate this high resolution. Multiplexing to just 8 output channels will contribute to lower frame rates, while higher frame rates can be achieved by partial read out, windowing and subsamples modes. The power dissipation results in 1.1 W at full resolution and frame rate. Using lower frame rates will ensure power conservation.
A 3-wire read-write SPI control enables driving and programming the on-chip features such as HDR modes, offset and gain programming, and power dissipation control.
The company currently manufactures monochrome variant of the CMV20000 image sensor. A RGB Bayer CFA filter-based color variant will be rolled out during the Q4 of 2012. Equipped within a ceramic 143-pin PGA package, this new model ensures operation within the -20ºC to +70ºC temperature range.
Third parties can access CMOSIS, under specific agreement for applications beyond the traffic field.
