I have some questions from my customers.
They are using ADF4xxx. (ADF4007, ADF4107 etc)
When some signal are inputted into I/O port, REFIN port and other input ports before power-on,
are these devices damaged ?
Or how much mA or V is allowed on these port before power-on ?
Power-on means that Vcc is biased with the appropriate voltage, not POWER DOWN.
