General description
Dragster is a platform of digital line-scan sensors. The sensor family is made using three types of basic elements: A single line element from 2K to 8K pixel resolution (7 μm pixel size and pitch), a dual line element from 2K to 8K pixel resolution (7 μm pixel size and pitch) and a single line element from 4K to 16K pixel resolution (3.5 μm (H) x 3.5 μm (V) pixel size). The chip versions with dual line are optionally available with Bayer Pattern RGB filters placed on the sensors.
The sensor features a low noise pixel with true CDS and global shutter for interleaved readout and integration operation. Each pixel has an on pixel 13-bit ADC and its gain can be programmed in a range of -6 dB till +20 dB by means of an 8-bit DAC controlled over the serial configuration interface.
The readout is made by two 13-bit wide digital taps organized in odd/even order for each 2K segment. For each line segment, 2K (7 μm pixel) or 4K (3.5 μm pixel), all pixels are read out. For sensor versions with 3.5 μm pixel pitch, two 2K segment readout circuits are placed on each side of the pixel line, to lead to a basic segment of 4K pixels, where even pixels are read out over the bottom readout and odd pixels are read out over the top readout.
Start and end of integration, as well as optional start of readout, are started upon individual external trigger events.
To enhance dynamic range multiple non-destructive readouts are possible.
