Re: [USRP-users] Use of an external 10 MHz or 1 PPS reference?
Thu, Jun 11, 2015 4:45 PM
If you had to choose (which it doesn't seem you
do), the 10 MHz reference would be better suited for frequency
stability, but doesn't provide any kind of time reference, which you'd
need, e.g., for synchronizing devices in time.
Cheers,
Martin

Re: [time-nuts] PRS-10 input and output calibrations
Sun, Apr 22, 2012 8:47 PM
With factory default settings with 2 PRS-10s, connecting 1PPS_out from one
unit to 1PPS_in on the other, would not align the 1PPS_out pulses. They
were off by several hundred of ns. It was probably an operator error
somewhere.

Re: [time-nuts] 10 MHz to 32.768 kHz converter
Mon, Mar 21, 2016 9:37 AM
Answer: with a 10 MHz PIC the best you can do in theory is +/- 200 ns on every 32 kHz edge, with no accumulating phase error, and perfect frequency accuracy for tau 1 s and above. And my divider meets theory.

Re: [time-nuts] What's the easiest way to divide by 10 for Thunderbolt reference output?
Tue, Jul 24, 2012 12:30 PM
Use a divide-by-10 (7490-like) set to divide
with 50% duty cycle or divide by 5 then by 2.
