GPSDO PLL tuning
« on: May 26, 2024, 06:12:46 pm »
Hi,

I am working on a GPSDO based on Lars Walenius' design,
and looking for information on how to optimize the PLL parameters (PI loop)
Such as the : Gain, Time Constant and Damping.

I am (reasonably) familiar with the PLL theory (R.E. Best, F.M. Gardner and other references).
Lars provides some hints on how to tweak and optimize the constants in his design,
but it does not cover the whole story, and I have difficulties to connect theory with practice.

I would appreciate sharing experience gained on similar systems.
Thanks for pointing me to such helpful references if you know any.
