Dear GuysNGirls,

I'm the new guy :) in this forum and also in image processing...hello to all.

first of all: sorry for my bad english, this isn't my national language.

I have a problem here and I hope you would help me.

I want to sample the video output from a NIR sensor into 16bit (ADC). This sensor only have 2 outputs:

1) pixel/video out.
2) trigger signal for ADC.

So I don't have any reference signal.

- Video out is between 1V (offset) and 3V(saturation).
- Pixel Clock = 5MHz
- 192x96 pixel

I need best accuracy.

So I never develop a board/circiut for an NIR sensor and this is why I would ask you:
How would you do that? Do you know suitable ADCs for me? And would you reprocess the analog pixel signal before sampling?

Is it eneough to have an 16bit ADCs with Bottom Reference=1V, Top Reference=3V and 5-MSPS (see attached file "schematic")? Or is this to easy?

I would like to discuss with you about possible circiuts, suitable OPVs and ADCs...the whole hardware stuff for getting pixel data into my pc :)

Thanks for your productive RE !

greetings fizz

i think im in the wrong place...could an admin please move through the analog circiut area?
 

@admins: is it possible to move me to the analog circiut area? please...i want to discuss a little bit :)
