The preliminary information of the BBD module has been updated. I think that
the main features of the module are defined in the meantime. But there is
one thing that leaded to internal discussions in the company and I'd like to
hear your comments:

Should we manufacture a single module similar to the prototype shown on the
page with 2048 or 1024 stages BBD (can be chosen by the customer in his
order). The pc board will be designed for both types which are unfortunately
not compatible.

Or do you prefer a double module with both BBDs on the module. Both
solutions have advantages and disadvantages. The main advantage of the
single module is the lower price. But one would need two of these modules to
have both time ranges available (down to 7ms or 2,5ms resp.). The advantage
of the dual module would be the lower price if both time ranges are required
simultaneously (compared to two single modules), and the mixing
possibilities of both BBD sections. But the lower price is attainable only
if the module contains only one HSVCO for both BBDs. Otherwise the price of
the double module will be nearly the same as for two single modules.

I'd prefer the single version (though I voted for the double version in the
past ...).

I can't wait to see your comments. Bakis, maybe you could start a poll (very
simple: single or double module prefered).

Best wishes
