MAX2871 / MAX2870 lock time

Category: Datasheet/Specs
Product Number: max2871


I looking to use either the MAX2871 or MAX2870. I am wanting to ask how fast can I get these PLLs+VCOs lock? Specifically when I want to change frequencies. I am curious from when I program a new freq and the PLL locks, what is is the fastest time that can be achieved with these PLLs? 

Please include the LPF bandwidths, Frequency of PFD, and frequencies (start and end freq.).
