CMOSIS, the leading European supplier of advanced CMOS image sensors, starts sampling low-cost versions of its CMV2000 and CMV4000 imagers in May 2015. The new versions differentiate from their CMV equivalents by their IC package, being LCC (Leadless Ceramic Carrier) instead of µPGA. With these low-cost versions of the CMV2000 and CMV4000 devices CMOSIS is extending its state-of-the-art product offerings to high-volume markets.
LCC – Same Functionality at Half Price
The new low-cost packaging format enables CMOSIS, depending on type and order volume, to offer the CMV2000/ CMV4000 imagers at about half the price of the current µPGA versions for volumes over 5000 pcs/year,. Besides being lower priced, the LCC-type package offers the additional benefit of surface mount assembly, allowing more compact cameras designs and more economical camera assembly. The LCC version’s electro-optical performance, speed and defect quality are identical to the corresponding µPGA devices. CMV2000 LCC version is already in production as a custom variant for more than a year and several tens of thousands devices have shipped.
“We are delighted to explore new and highly attractive market segments for our proven state-of-the-art CMV product line”, said Lou Hermans, Chief Operating Officer of CMOSIS. “The LCC packaging format will open up a host of high-volume applications and further broaden our strong worldwide position and customer base for advanced camera designs.”
LCC – Smaller Package with 2.2 or 4.2 MP
CMV2000 and CMV4000 are high-sensitivity, pipelined global-shutter CMOS sensors. Their advanced pipelining allows for exposure during read-out, by integrating a new frame while reading out the foregoing frame. The state-of-the-art pixel architecture enabling true correlated double sampling (CDS) as pioneered by CMOSIS thereby significantly reducing fixed pattern noise and dark noise.
CMV2000 and CMV4000 imagers integrate 16 LVDS channels each running at 480 Mbps resulting in a frame rate of 340 fps for CMV2000 and 180 fps for CMV4000 (10 bit/pixel). Row windowing and subsampling result in a high frame rates at full resolution and 10 bit per pixel. A 12 bit per pixel mode is available at a reduced frame rate. Driving and read-out are programmed over a serial peripheral interface. An internal timing generator produces the signals for read-out and exposure control, while external triggering remains possible.
The essential difference between the CMV2000 and CMV4000 sensors is in their resolution: The 2.2 Megapixel CMV2000 offers 2048 x 1088 active pixels, whereas the 4.2 MP CMV4000 comes in a larger 2048 x 2048 layout. Pixel size for both products is 5.5 x 5.5 µm resulting in a 2/3” optical size for CMV2000 and 1” optical size for CMV4000.
NIR versions are available (E12) for enhanced NIR performance targeting security, automotive, night-vision, inspection and distance measurement applications.
The CMOSIS group is a major player in the industrial, scientific and professional markets for CMOS image sensors, covering applications such as machine vision, high-end digital photography, digital cinema, aerospace, scientific, medical and biometry. CMOSIS offers off-the-shelf, semi- and full-custom CMOS image sensors. CMOSIS employs over 100 people at locations in Antwerp (Belgium), Nuremberg (Germany) and Funchal (Portugal). CMOSIS’ product range include high speed, global shutter and rolling shutter area CMOS image sensors with resolutions ranging from VGA to over 70 million pixels. Through the acquisition of Awaiba the product range now also includes a wide range of CMOS line scan sensors with up to 24k pixels and line scan rates up to 80k/s. The Naneye imagers and camera modules target endoscopic and other space constraints imaging applications.
