Clean Square wave from Signal Generator

[jonnybgood]

Hi,
I need a clean square wave of pk 3.3V to feed to a uC. My signal generator outputs a distorted square wave and I need to clean it out.
I will use frequencies from 100kHz - 500kHz. My friend suggested a Schmidt inverter. What shall I use? If it is possible something that is a little bit common.

thanks
