I have two questions:
1. What voltage is VCC_REG_OUT?
2. What changes to the circuit need to be made to change from VCC_VCO=5V to VCC_VCO=3.3V operation?
Thanks,
Michael

Hi Michael,
We recommend using an external LDO for 3.3V operation too. For this reason, VCC_REG_OUT should be left open. All needed is connecting 3.3V supply to VCC_VCO and VCC_LDO pins for hardware side. The ALC settings should be set for 3.3V operation when programming the part.
