Hi, I think Gardner's book is good but was written before the charge pump PLLs with digital phase detectors. Best's book is very detailed on describing locking process, but I don't find it useful for much else. "Frequency Synthesis by Phase Lock" (William Egan) has some chapters describing frequency dividers and phase detectors. Several of Razavi's books give pretty good introductory analysis of PLL systems, as well as oscillator design. (He also has a book on PLLs that I haven't read yet, so can't tell you about that.) Also, Dean Banerjee has an applications oriented PLL book, which has a lot of details on PLL loop filter design, and you can download it for free (the last time I checked) from National Semiconductor website.
Hope that helps.
