Linear CCD-s

[raivo]

I deicded to experiment a bit with linear CCD-s. I have some Toshiba and NEC sensors and also got datasheets. Still it seems that i need more understanding what all these clock pulses are for. Usually at least 4 different clocks (such as phi1, phi2, RS, BT) must be supplyed and it seems that timings must be quite precise. Some grayscale sensors have two (or more) signal outputs (such as OS and DOS for example). Datasheets do not explain what circuits i need to get single signal for A/D input.

I also found with Google some texts about CCD theory but these are a bit too theoretical for my use. Linear CCD-s are only mentioned there.

Maybe someone knows good application notes about some common linear CCD sensor (such as those used in faxes or cheap scanners) or simply can explain all these meshy signals?

All CCD's are variations of analog bit-buckets. As a general rule, therefore, is that they need a minimum of 2 clocks to shift analog data down through the array.

Suggest you look some more for the app notes. Fairchild and EGG Reticon used to have some pretty descriptive app notes.
