120MHz crystal oscillator

If we get back on topic:



The diagram Mike shows shows a single crystal oscillator.

Can we just start out with a 120MHz crystal oscillator to start with instead
of having to to run a 20MHz one through a doubler than tripler?

The diagram is from 1989 so maybe 120MHz ones weren't available then
but doing a short search, it seems there are 120MHz crystals available.

Is there any reason we can't start with a 120MHz one?
