Voltage level problem on a pin which is a clock

So I had some spare time and did some experiments. I made a 125MHz output with 8mA drive strength and 24mA drive strength,

both with and without the attribute "fast output register" on and off. I noticed little or no difference.

But what made a big difference was the way that I measured the signal. With an x1 probe, I got the same result as hinanotabu86,

with an x10 probe, the signal levels looked alot better. See attachment.

This is a 3V3 output pin. The scope has a B/W of 200 MHz. Same scale for both signals.

For the x1 probe (green): Vmin = 800 mV, Vmax = 2V.

For the x10 probe (yellow): see scope picture.

So I think your signal is fine, but the way you measure it should be improved.

Good luck with your project, Ton
