I use the EV-ADF5355 evaluation board. After power down the setting is lost. I would like to know if there is any chance to store the synthesizer configuration on board. And maybe have it automatically programmed after power up
I think you mean switching off the power of the part. No, that is not possible. There is an EEPROM on the board but that is used only for GUI to recognize the board.
Software power-down should not cause the registers to be lost.
