We are running the ADF4360-9 beyond the published temperature specs. The circuit has been run up to 125 degrees C and appears to work fine for our application. Do you have any information as to the long term effects of operating the ADF4360-9 at this temperature for extended times? Is there a danger of damaging the device when cycling the temperature 25 - 125 degrees C.
The power that supplies the ADF4360-9 has a very slow ramp up time to 3.3 volts. Is there a startup problem for the chip? Will all of the internal circuitry operate properly with a slow moving power supply? How soon can information be sent to the device after the power supply reaches 3.3volts?
