          I use QFAB QFN48 schematic with internal LDO setup,but my board have not 32.768KHZ.

the Pre_processing current is big when in adverting .Why?

I have started seeing this issue with the rev 3 Silicon chips. I do not use an external LDO. I run in internal LDO mode. At the rising edge of pre-processing during any RF event I see 19.5mA current spikes. I haven't been able to determine root cause yet. Any update on this?
