Running at 200MSPS

200 MSPS working now

I'm finally sampling at 200 MSPS. for some reason I'm an expert to misunderstand datasheet.
This morning... I read carefully the ADC's datasheet and I wrote correct UCF file for my Xilinx device.
look by yourself:

10 MHz square wave

The waveform compared with the same inoput signal published in my previous post looks much more like a square wave, obviously as I can only have the first 3 harmonics... it can't get better than that, even if I increase the input bandwidth. Therefore I'm really satisfied. 

1) assemble and test channel 2
2) finish to design the USB isolation module (I don't want to damaged my PC)
3) to complete the SW!
