It is.

All the Pads have a cut-off frequency somewhere above 100 MHz. When we
can run faster someday with smaller nodes, without a PLL, we could not
tune up the clock frequency above this cut-off frequency.

ok.
 
so, from somewhere, we need a libre licensed PLL. is one in development somewhere? 

is it worth putting in an extra (small) NLNet grant application for?
