• Development of phase-locked loops from analog to digital and optical, with consistent notation throughout;
• Expanded coverage of the loop filters used to design second and third order PLLs;
• Design examples on delay-locked loops used to synchronize circuits on CPUs and ASICS;
• New material on digital dividers that dominate a frequency synthesizer's noise floor. Techniques to analytically estimate the phase noise of a divider;
• Presentation of optical phase-locked loops with primers on the optical components and fundamentals of optical mixing;
• Section on automatic frequency control to provide frequency-locking of the lasers instead of phase-locking;
• Presentation of charge pumps, counters, and delay-locked loops.

The Second Edition includes the essential topics needed by wireless, optics, and the traditional phase-locked loop specialists to design circuits and software algorithms. All of the material has been updated throughout the book
