Hi Murray,
Why did you use such a large division factor - or any for that
matter? Could you not just have used a PLL with very long time
constant running at 10 MHz?

On-Semi makes a programmable delay: MC100EP195, 2.2 to 12.2 ns in 10 ps steps
There are a couple of other similar chips.

Subject: [time-nuts] Yet another GPSDO - locking to 10MHz
I have a design which locks a high performance 10MHz OCXO to a 10MHz
source which should work equally well with the LEA5, or any source of 5
or 10MHz.

I designed it for use with a distributed factory GPS reference which has
