PN5180 BGA signal definitions

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

Hello Mohamed,

    You can float these 2 signals on your deisgn!  no any effect for your solution.

Best Regards,

Hi Sun,

Thanks for the reply. 

Just curious, what are these signals for? Full signal definitions would be very helpful.

Thanks,
