Hello all,

 

Has anyone used PN5180 in BGA package? I have got the pinouts for the package (under NDA) but there seems to be couple of signals which do not have proper definitions. 

 

Signal #1: PRD

Signal #2 : TVDD_IN    

 

- Note that there is already a TVDD pin in the package. I am not sure what TVDD_IN is for. Further, TVDD and TVDD_IN are not connected inside the package.

 

 

Any ideas on what these signals are used for?  

 

I have raised a support question with NXP.. but they have gone quiet.. :-(

 

Thanks,

-Ismail
