What's your intended load impedance?

I was measuring my clock signals via an oscilloscope at High Z. I saw some shabby signals so I expected this to be the result of reflections due to bad termination (1M instead of 50 Ohms). However the professor supervising my project didn't thought the clock signals were that shabby. I want to drive an ADC with the clock signals. I expect the ADC to have a high impedance clock input, although the datasheet does not provide any info about the clock input impedance of this ADC. So actually there seems not to be any problem at all (due to the high impedance nature of the ADC clock input).
Besides that, the datasheet I found during a quick search (
https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/cyclone-v/cv_51002.pdf) states that the maximum DC pin current 40 mA's is. That is a lot more than the 16 mA for a certain driving mode. So maybe there are no problems after all.
Thanks for the info!
