Hey guys! ı have X20 bord and ı just try to design own smartwatch. with mt6739 but ı cant find datasheet of MT6739. MediaTek X20 board put the decoupling caps. front of the DVDD_CORE pins. why ???
You should contact Mediatek for this, I think it’s under NDA.
I’m not a hardware expert, but what do you think is wrong with that? they are connected between DVDD supply and ground to keep DVDD stable, absorbing high-frequency noise.
yea ı know that its filter for high-frequency noise. But they commected some pins (its not randomly connection) ı wonder why connected this filter caps. for some DVDD pins.
