29.3 Clock Recovery
The setting of clock recovery is the same as Eye Diagram. Refer to the section "Clock Recovery" in
the "Eye Diagram" chapter.
29.4 Jitter Decomposition
Jitter typically consists of various jitter components that are caused by different jitter sources. For an
analytical approach, a jitter model is frequently used, which splits jitter into two major categories of
random and deterministic jitter.

The benefits of jitter decomposition
：
1. Jitter performance plays a crucial role in the bit error rate of a high-speed digital
communication system. Through a limited sample, the jitter measurement value can be used
to estimate the TJ at any bit error rate if the RJ estimation is correct.
2. Jitter decomposition is a key tool to accurately derive each type of jitter as well as total jitter
in a system and identify the root causes of jitter quickly.
