Hi, It doesn't look like the F9P does anything special for timing - the timing specs given in the F9T spec sheet are 5 ns (1-sigma, clear sky, absolute mode) and +/- 4ns jitter, but for the F9P are 30ns RMS and 60ns for 99%.
I think I want an F9T :) Angus. On Mon, 21 Jan 2019 09:00:33 -0500, you wrote: >Hi > >Ok, so the product summary page on DigiKey very clearly shows the >frequency coverage information.
