Hi Vicente,

Thank you for your reply and support.

This is an issue that was previously supported by E2E below.
https://e2e.ti.com/support/clock-timing-group/clock-and-timing/f/clock-timing-forum/1301392/lmx2820-lock-detect-pin-status/4986735#4986735　　

I sent you a private message about the loop filter and reference source, so please check it out.

We will also send you the EVM and customer board results regarding phase noise.
The layout of the customer board is also included in the materials.
Could you please comment on the cause of the difference in phase noise between the customer board and EVM?

Best Regards,
Ishiwata
