Use a limiting or post amplifier with CML AC coupled input. Check with
Micrel or Maxim. Probably need to do a bit of attenuation using either pi
or tee network (or simply use a 20dB pad externally), but I have solved this
problem before. You did not specify either jitter or rise/fall time
requirements so this is the best answer with info. provided.
