[resets]

Has anyone ever build a PLLXO with LR instead of RC Filters?

Is the any calculator to desgin it?
Many thanks

Note that anything over 1st order has some limitations.

resets, do you have high quality cored inductors?

Just switch between RC to RL.

As Adason poimts out.mylink is for an RC PLLXO, but they can be LC. Inductor values are huge. Marchand makes the job easier by terminmating with a 5k R, so you need an amp with vey low R_in, and a preamp with very nhigh R_out. You need the same with a 2nd order RC PLLXO.
