Hi Paul,
Thank you for your advice.
The system clock source is 12.8Mhz tcxo from Rakon E2747LF.
We already use this tcxo in our different product and pass the G.8262 test cases.
The EEC1 require 4Hz loop BW and EEC2 require 0.1Hz loop BW.
So we are trying to be EEC2 compliant.
Thanks and best regards.
MK.
