ADF4159 Digital Settling Time

This question is a purely digital question, I am not asking about the tuning time requirements of a VCO or loop-filter, only the digital time requirement.  I was asked this question

 

Question: Directly after the PLL is programmed through the SPI interface, how much settling time is required before the device can be re-programmed?  I could use the Lock Detect as an indicator but I would like to know the exact amount of time needed between SPI tuning commands.

 

Thank you
