Can I use a Sinewave Clock Reference of +10dBm with ADF4110 with no damage?? I have operated the PLL with 0 dBm Sine wave Reference Clock, that worked fine. What about +10dBm ??
Datasheet provide maximum rating for CMOS REF clock... For positive cycle it is = 3.3V and for negative cycle it is = -0.3V....With +10 dBm sinewave, positive cycle is OK because peak walue is +1V. But i am confused with negative half cycle. -1V (peak in negative cycle) is out of the limit (-0.3 V)
