A Couple of Questions about ADMV4530


I've not seen anything in the DS to clerify:

  • Can the reference be different from the 200MHz specified, if so, what are the Min and Max values?
  • What is the minimal level for the Ref_In power for operation? Only AMR voltage levels are specified.
  • There is no order for the voltage supply activation, is the device protected?
    • If I apply only the 4V voltage, is there a chance of damage if I then, by mistake, send an SPI command?
    • I've noticed that on the EVB the output of the 1.8V regulator is enabling the 3.3V regulator, is this mandatory?


Thanks is advance.
