AMC1035-Q1: digital input CLKIN with Schmitt-Triggers?

Hello,

for the non-AEC-Q device AMC1035 a Schmitt-Trigger for the clock input is stated in the datasheet:

For the AEC-Q device there is no Schmitt-Trigger and no hysteresis mentioned in the datasheet:

Is there a Schmitt-Trigger with hysteresis at the clock input of AMC1035-Q1?

Can I apply an RC-filter at CLKIN e.g. with a time constant of 8 ns by a clock frequency of 20 MHz or requires the automotive device a faster edge?

Tanks
