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.

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 Rin, and a preamp with very nhigh Rout. You need the same with a 2nd order RC PLLXO.

Yup. Show us some pictures, fr responses.
Long time ago i was interested in making active equalizer using inductors, but abandoned the project because of lack of high quality inductors. Then i purchased shiit eq, which does all that, so i replaced behringer ultracurve, used for measuring purposes only now.
