Hi  Experts,
I am designing 6 layer board with  the  mixed-signal RF tuner + digital 
demodulator, utmost care needs to be taken in the PCB routing of the analog 
blocks, grounding, placement and antenna placement/ground palne,Also i m using 
0.5 MM pitch BGA package,so  anyone can suggest that for bga package, what 
specification to be require in Layout. Like... via size,track width , tarck 
clearence.......and all important terms.

So, i can follow the same criteria to reduce the noice beetween Analogue and 
Digital Section. 
 
All traces have to be simulated to have proper 50-Ohm impedance.



 
Best Regards,
 
Jweta Patel
