Operation Amplifier for video-ADA4891-1


I'm using the ADA4891-1 in a non inverting application - With amplification of 2.

I'm using VS=3.3V , RG&RF = 604 Ohm, Input resistor-Rt=200 Ohm, I have 100n and 10u Capacitors betweren Vs and Gnd, Input Voltage=1V, output Voltage=Ringing!!!!!!. I change Rf to 0 Ohm and I get a "1" Amplifier without ringing!!!. What may be the reson for that?

Best Regards
