ADF4108 RF Input Sensitivity

Hi. I am planning to use an ADF4108 for my PLL design. However I am confused by its maximum value of RF Input Sensitivity. From my understanding, according to the datasheet, the max power I can feed back from the VCO is +5 dBm. However, in the hardware documentation for its evaluation board (EVAL-ADF4108EB1) , it is stated that the ADF4108 RFIN input sensitivity spec of 0dBm MAX should not be exceeded.


Which value should I follow, 0 dBm or 5 dBm?
