ABSTRACT
This chapter examines the types of jitter in directly transmitted data signals, the methods for measuring each one, and some of the impacts they can have on system operation. It also looks into some of the system design approaches that can be used to minimize or mitigate the impact of jitter. Jitter of several types can be described and measured. In general, the differences have to do with the frequency of the recovered jitter modulation of the data signal's clock. Different frequency bands are used to describe the types of jitter. Also related to the descriptions of the various types of jitter are the methods for measuring them. Jitter occuring at a rate greater than the highest frequency defined as wander is termed timing jitter. Greater detail regarding the characteristics of jitter in any particular case can be obtained by triggering the scope with a clock extractor.
