ADF4351 lock vs temperature

Dear,

we've seen in ADF4350 a special case for cold temperature at VCO calibration side. Chip would be reprogramming (text below Figure 21 in datasheet).

About ADF4351, does calibration is valid for entire temperature range when it was done at extreme temperature (at -40 or +85°C)?

 

Our goal is getting a continuous carrier over temperature range (NO phase shift or sweeping vco for CAL).

 

Best regards.

 

Dan
