Excel document to convert Phase noise data to Allan Variance...

Hello,

I've used this Excel based calculator to convert phase noise to jitter (if Allan Variance is a similar thing?) based on your frequency start / stop end points:

This is also another tool from the same folks which runs on the desktop:

Also, you may have seen the Clock Architect tool on Webench as well which allows you to compute jitter by plugging in phase noise (dBc/Hz) data:

Hey Hooman,

Thanks so much for your response but I believe jitter and Allan Variance are a little different. They both seem to be methods for understanding your deviations in frequency but Allan Variance is more statistically based.

Have you ever heard of this document or would you know of someone I could ask?

Thanks for your time,
