Hello all,
I want to design a 30MHz clock buffer using the LTC6252/3/4. the input is actually a clipped sine wave TCXO with 0.8V amplitude.
I don't have many experience in designing with opamps, so I used LTspice.
The design look like this (Singe 3V supply, G= ~1):
Running the sim in 10MHz looks fine:
As soon as I go above ~30MHz, for example 50MHz, the output is distorted and looks more like a triangle wave:
Can someone please explain why this is happening?
Thanks a lot!
Nir
