Hello Shoujie,

As I informed you earlier, unfortunately the only way to have these numbers is to test it using your board design. This would take 4~5 months for design, preperation and actual test!!

Hello Shoujie,

once I have checked this with our experts, I was asking them about the package (QFN64) not the specific IC, to get any possible suggestions, but unfortunately we do not have any for this package!
