LMX2594: Quick Frequency hopping

Part Number: LMX2594

Hi Team,

Please advise me on my questions bellows:

Q1. Do you think it is possible hopping two frequencies with in less than 1ms?

The datasheet states on page 40 that, during power-up, all registers except R0 should 
be programmed first, followed by a 10 ms delay before writing to register R0.
Does this requirement apply only during power-up, or does it also apply during normal 
operation after the device has already been initialized?

In other words, is the 10 ms delay required only for the initial power-up sequence, 
or is it also required  for subsequent frequency changes during normal operation? 

Q2.  Can you provide me a list of registers which are necessary to be modified when 
    LMX2594 change its frequency one to others.

Q3. If frequency change is inside the VCO band (ex:10.8 GHz -12.0GHz), are there any 
    registers can be removed from the list?
