> If you ever plan to operate high efficiency backside thinned chips (like the Marconi CCD42-40) you might find that parallel clocking times increase somewhat.  In this case the unique 'dump drain' facility on the 42-40 allows much faster clearing of the chip.  The data sheet (on web page below) for the similar 42-80 device explains it....

Could You please advise me which of Your backilluminated CCD (1kx1k or 2kx2k) are able to be clocked as fast as Zhao wants. We are very interested in fast backilluminated CCD but Your distributor could not explain which are good for fast clocking and which performance they achieve in this mode (2 -10 Mhz, readout frequency). We use the 2k
x2k TH CCD and we are pleased with the quality.
