AD9268 input protection

We use adl5201 as adc driver for AD9268, and ADL5201's output can reach 10Vpp, we are worrying this will breakdown the AD9268 since its maximum rate is −0.3 V to AVDD + 0.2 V. We note there are some ESD diodes in its input pins. Is this enough to protect AD9268 from burn out? Or we should add some clamping diodes outside?
