A complicated system design can often require 10 or more clocks with different frequency sources, making it difficult for designers to select the best timing solution. Designers must choose between discrete resonators, crystal oscillators, fanout buffers, clock generators and other timing devices, while considering board area, cost, system timing margin, noise immunity and electromagnetic interference (EMI). Consolidating frequency sources into clock generators can minimize the number of components and cost, while improving system ruggedness and reliability. Read this white paper to better understand the benefits and limitations of alternative sources.
