Phase-Locked Loops Demystified

Over the past decade, Phase-Locked Loops (PLLs) have become an integral part of the modern ASIC design. PLLs provide the clocks that sequence the operation of the various blocks on an ASIC chip as well as synthesize their communications. There are various types of PLLs targeting specific applications. Read this white paper to learn more about the types of PLLs and how they work in certain technologies.
