Dears:

From the below picture there are 2 issues:

1. What the function about AC Coupling capacity? Could we delete the design?

2.Why does there have 3 different voltages? Is there some specific description about clock of CC2642R?

Note that the post you have collected the diagram from state that a solution with CC26x2 has not been characterized and we therefore not recommend using TCXO before we have a reference design out.

Why do you think about using a TCXO? A TCXO is typically only needed in narrowband systems.

From PM's second response in the thread you refer to"As this solution (Use of TCXO) is not fully characterized yet , we don't recommend to use TCXO at this time."

Why do you think about using a TCXO? A TCXO is typically only needed in narrowband systems.
