I am new to this area, would really appreciate help on my queries. We are trying to do some EMI studies for which we are using this IC as a signal source.
1. If i dont want to use the eval board for ADF5355, how do i control(program) our custom designed synthesizer board that uses ADF5355 IC? I see it is 3-wire SPI compatible, but do i need an arduino/any MCU to control it?
2. Does it store the last program uploaded in the chip after every power cycle or do we have to burn the code everytime the board is turned ON?
3. If we have 20 of our custom designed synthesizer boards, whats the easiest way to control all of them together?
