Hi everybody...

I'm looking the DK3200 schematic, and trying to understand why the LM339 IC.- Could someone tell me the function of the comparator and the use of it?

Thanks.-

Excellent question! It just provides two signals, routed to the J3 connector. You can watch USB activity on these signals.

I guess that it has been put there by the DK3200 designer at a development stage, and forgotten in the final release...

Forget it, and don't use it in your own design.
