Si5351 needs a 25 mhz reference. The gps will produce a 10 mhz reference. If you pass the 10 mhz through a d flip flip, you will get a 5 mhz output, rich in odd harmonics. Feed that to a band pass filter to isolate the 25 mhz output and drive the si5351

Thanks, indeed also a very nice project.

However, I would also like to understand where the project with GPS is limited in frequency :-)
The project with the clock module demonstrates it is indeed possible to generate locked higher frequencies.

Thanks again,
