MC1320x RF Circuit Question...

Hi,
 
Sorry if this is the wrong place to post this question, but I didn't see other forums with 1320x information.
 
My question is what is the recommended value of the inductor between the balun inputs when using the Murata LDB212G4005C-001 balun?
 
In the MC1320x RF Daughter Card User's Guide, this is listed in section 5 (or 6) as L103 with a value of 3.9nH.
 
In the MC13201 Data Sheet, on the other hand, this is listed in section 8.8 as L2  with a value of 6.8nH.
 
Other than this, the two circuits are identical.
 
Thanks for any pointers!
