True to its title, this is not an introductory text, but it contains an amazing amount of information on PLLs of various kinds (including fractional-n synthesizers with sigma-delta modulators) and on their applications in systems. The material is well organized and reads smoothly in spite of the inclusion of substantial mathematical developments. The author provides mathematical background with apparent ease and rigor but also offers practical recommendations and a large collection of useful formulas and graphs. The work is well illustrated and most graphs are referenced to the MATLAB® scripts (included on CD) that produced them. The availability of the scripts and extensive references facilitate further pursuit of the material covered. The author has taken the care to provide an errata, and also as a complete table of contents, on his web site, which I found by searching for his name with the book title. This is an excellent reference for engineers who work with phase-locked loops.

The book starts out with a broad view of the phase-lock concept, pulling together perspectives from signal processing, estimation theory, and traditional circuit theory. It presumes some prior familiarity with the PLL subject. It has an excellent treatment on loop filters, well beyond what has been published before. The treatment on delta-sigma based fractional-N synthesis is particularly good as it starts with the historical patent record and takes the reader through all of the basic concepts up through important caveats to stay clear of. The final chapter is an in depth examination of PLLs used for bit sychronization and clock recovery. The books thorough treatment plus the inclusion of all the Matlab code used in preparation of the text makes this an excellent technical reference worth adding to one's personal library.
