dsPIC33EP32MC202 external clock source input?

Hello,
I want to use an external clock source (TCXO or VCTCXO) instead of crystal for dsPIC33EP32MC202. I found that OSC1 is driven with external square wave from rail-to-rail (EC clock overshoot/undershoot < 250 mV required) in DS70000657H-page 405.
 
But what are the minimum requirements for external clock source signal, like peak-to-peak value, coupling mode(DC or AC)?
 
The output of my TCXO is clipped sine wave with 1.48V Vpp. Can it meet the requirements for external clock source?
 
Thank you!!
