Yes, but can this be replicated with a standard GPS module?
And does it have side effects?

48MHz as stated in the Timing AppNote.

My current progress is that the uC i wanted to use does not
do what i want. Can anyone recommend a uC with 32bit timers
and IEEE 1588 support?

The alternative would be to use an FPGA, but i'm reluctant to
do that as it makes the whole system a lot more complex.

Why does it take years to find the answers to
the questions one should have asked long ago?
