Zero crossing detector with AD790

Hi every !

I'm designing a Zero crossing detector with a AD790 ,  the input is a +/- 10V sinus signal  .

Output should be hight if Vin > 0V and low if Vin < 0V

I'is working , BUT a have a lot of oscillation at the output .

Is it possible to add a couple of resistor to make a hystérésis with  AD790 ?

How much should be the hystérésis ? ( 10mV , 50 mV ?? )
