Z3r0 Posted August 28, 2015 Report Share Posted August 28, 2015 Hello, I have probably quite newbish question. I Would like to make something very simple to test my osiloscope frequency capabilities. So for example a 100 mhz square wave on one of the papilio outputs. The problem is that it seems the most I get is 32mhz and that is not square anymore, but sinusoidal I am able to configure DCM, addiding a counter after the DCM to slow down I can see that internaly papilio is working just fine on 100mhz. But not the output. I also saw that guys interface in quite high speeds with LVDS. So am I missing something or spartna 3E just can't handle any more than ~20MHz ? Tried to search forums/dataheet, but just can't find anything regarding frequency and IO. Any kind of information would be nice Thank you Quote Link to comment Share on other sites More sharing options...
