if it's suitable to choice a clipped sinewave for HMC767 and HMC778

Now,I want to use HMC767 and HMC778 to generate a X-band signal,  A 50MHz TCXO is intended as a reference crystal. the ESPON's TG-5500CA is a clipped sinewave output, if it's suitable to choice  for HMC767 and HMC778? or is there any other good choice for or HMC767 and HMC778?  

THANKS!
