Hi It’s just like the other uBlox modules (and just like the F9T …) the external input is a once a second time stamper with an 8 ns resolution (just like the +/- 4 ns on the sawtooth ….). One would *guess* they are using the same free running / TCXO clock for both the PPS out and the timestamp coming in.
