Jitter is extremely important in systems using PLL-based

clock drivers. The effects of jitter range from not having any

effect on system operation to rendering the system completely

non-functional. This application note provides the reader

with a clear understanding of jitter in high-speed systems. It

introduces the reader to various kinds of jitter in high-speed

systems, their causes and their effects, and methods of reducing

jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.
