[time-nuts] PLL question

[gonzo moto]

Hi Guys,
I'm in the process of building a GPSDO which started out life based on G3RUH's design, but suffered a bit of feature creep.

The GPS I'm using is the NavSync CW12, so I'll run the Freq_Out at 10MHz.
I'm wondering if I should run the PLL at 10MHz or if there is an advantage dividing the two signals down to (say)10KHz.
Does the averaging at 10kHz  (and introduced errors of the dividers) outweigh the 'no averaging' and no additional errors syncing at the fundamental freq?
I can think of arguments each way, but lack the test equipment to prove either way.

Suggestions would be appreciated.

Regards,
ian
