Thank you for support. I checked the datasheet again and I noticed that 1.8V(1P8) is for ADC die and 1.9V(1P9) is for VCA die. So I think that we should not use common power supply for 1.8V and 1.9V. About 3.15V(3P15), as this is for VCA die, we should also prepare 3.15V independently. Is my idea correct? Best Regards,
