Antwerp, Belgium, June 2012 – CMOSIS, one of the leading suppliers of CMOS image sensors for industrial applications, today introduced a 20-Megapixel image sensor for demanding, industrial applications. With the introduction of the CMV20000, CMOSIS broadens its current CMV portfolio of high-performing global shutters CMOS image sensors addressing the high-resolution segment of the industrial vision applications as well. The unique properties and features such as high resolution, high dynamic range and global shutter, are a perfect fit for high-end industrial imaging systems, automation systems and medical applications.

The CMV20000 image sensor features a 20 Megapixel (5,120 x 3,840) resolution with 6.4 um sized square pixels resulting in an active sensor area of 32.8 x 24.6 mm (35 mm film optical format). Peak quantum efficiency reaches up to more than 45 percent resulting in a superb responsivity of 8.29 V/lux.s in combination with an excellent dynamic range of 66 dB. By means of correlated double sampling in global shutter mode, the patented 8-transistor pixel cell architecture reduces any dark noise and FPN non-uniformity of the sensor matrix. The sensor also offers an excellent shutter efficiency, a common feature of the CMV image sensor family.

At full 20 Megapixel resolution and with a 12-bit ADC resolution the CMV20000 delivers 30 full frames per second. This is achieved by using 16 LVDS outputs running at 480 Mbit/s each. Lower frame rates can be supported by multiplexing to 8 output channels only. Partial read out, windowing and subsamples modes, can be programmed to support higher frame rates. At full resolution and frame rate, the power dissipation is 1.1W. This power consumption can be dynamically controlled when lower frame rates are used.

Driving and programming the on-chip features such as HDR (High Dynamic Range) modes, offset and gain programming and power dissipation control is done over a 3-wire read-write SPI control.

The monochrome variant of the CMV20000 image sensor is in production today. A color variant, with RGB Bayer CFA filter, will be introduced to the market in Q4 2012. It is housed in a ceramic 143-pin PGA package and can be operated in the -20 to +70 ºC temperature range. This extended temperature range makes the CMV20000 perfectly suited for most demanding and robust industrial applications.

The CMV20000 was originally developed as a customized, exclusive product aimed at complex traffic management applications. An agreement with the original customer allows CMOSIS to offer this imager to third parties for applications outside the traffic field.

CMOSIS is a pure-play supplier of standard off-the-shelf and application-specific CMOS image sensors for the industrial and professional market covering applications such as machine vision, high-end DSC markets, scientific, medical, automatic data capture and space. CMOSIS was founded in November 2007 as a fabless CMOS image sensor vendor providing in-house design, characterization and qualification facilities for research, development and volume production has grown continuously and consistently, currently employing about more than 40 people at it’s headquarter in Antwerp, Belgium.
