VDD VDDH DCCH Power configuration

VDD& VDDH& DCCH

Is the connection correct? What should be paid attention to when designing the power supply?

Hi,

The nRF will be in normal mode if you connect VDDH and VDD to the same node, which means that the first regulator stage won't be used which makes DCCH unnecessary. Please see the documentation regarding power supply and reference design for more information.
