600 VGA Frames Per Second: CMOSIS' CMV Sensor Family Expands To Lower Resolutions
At Vision 2010 CMOSIS previewed a new member of its proven off-the-shelf CMOS image sensors: the 0.3-megapixel CMV300. Laid out in a 1/3" VGA (648 x 488) format, featuring high sensitivity, low-noise, global shutter and high frame rate, the CMV300 is aimed at basic, cost-critical industrial applications. Prototypes will be out by mid-2011.
The new CMOSIS CMV300 will use the same advantageous 8-transistor pixel structure as the high-resolution series CMV2000/CMV4000 / CMV12000. With 7.4 µm square pixels, a low noise level of just 9 e- and a full well charge of 20,000 electrons, the new CMV300 realizes a dynamic range of more than 66 dB, which can be extended through several HDR (high dynamic range) operational modes.
The CMV300 pixel architecture, with its low parasitic light sensitivity and correlated double sampling (CDS) in global shutter mode, reduces the sensor matrix's fixed pattern noise (FPN) and the dark current noise. Pipelined operation enables integrating a frame during readout of the foregoing frame.
The sensor's 12-bit ADC delivers 600 full VGA frames per second over four LVDS outputs of 600 Mbit/sec each. They can be multiplexed to two channels delivering a data rate of 300 frames, or to one channel at 150 fps.
Imager control and readout are programmable via an SPI interface. An internal runtime generator delivers all signals for data readout and exposure control. An external trigger can override the internal generated triggering.
CMV300 comes in a monochrome version fitted with micro lenses, and in a color version featuring RGB Bayer patterns as well as micro lenses. Considering their cost-effective small housing, their wide operating temperature range and low power consumption of just 400 mW, both versions of the new VGA image sensor are well suited for rough industrial environments.
The comprehensive CMOSIS technology portfolio contains a broad range of basic IP claims for CMOS image sensors, such as high pixel count at a high fill factor and high speed, column A/D converters with large bit depths, wide dynamic range, TDI (time-delay and integration) implementation, low-noise pixel structures as well as novel rad-hard pixel concepts.
