As clock speeds and communication channels run at ever higher frequencies, engineers who have previously had little need to consider clock jitter and phase noise are finding that they need to increase their knowledge of these subjects.

This in-depth, very readable tutorial explores the many types, impact, and measurement of jitter. It is presented as on on-going series in eight sections, in Word document format:


1: Classes of Jitter (click here)

2: Types of Jitter Measurements (will be posted soon)

3: Wander (will be posted soon)

4: Time versus Frequency Domain Measurements  (will be posted soon)

6: Spurs (will be posted soon)

7: PLL Characteristics (will be posted soon)

8: Clock Buffers (will be posted soon)
