Capture time and Lock time of PLL

HI,
I am designing a PLL, and I wanted to know if I could get any formulae for the lock time and capture time of the PLL. I tried looking in Razavi's book, but cannot access it dont know why! if anybody could write the formulae here then it will be a great help.
Thank you.

it probably varies for individual types of PLL chips
what is the PLL chip you want to use, I would assume that info would be in the datasheet for the said chip
