Hi, all

I think most crystals output sine wave clks, but our digital need square wave clock,
so should we adopt a macro in our back-end process or just don't care about that?
I need a 200MHz clk!!

Thanks!
 

Use a sin to square wave converter such as a simple buffer constructed with two inverters.
