ADF4351 locking time

Hi,

According to the information in this forum, the ADF4351 has an option to cancel the sub-band calibration for small frequency jump to reduce the locking time. I'm looking for more information on this mechanism. The datasheet that I downloaded from Analog website has no information regarding sub-band calibration new feature. How to shutdown the auto calibration? What happens if due to temperature variation the synthesizer need to jump to nother sub-band? Do I need to calibrate the sub-band by myself?

 

Thanks,

Shlomi Arbel
