Jitter is defined for clock signal or data signal?

[pardis123]

Hi again,
In a SDH system, I think that Data stream is defined by the clock signal.
Do we define jitter for the clock signal (recovered from the data stream) or for data signal? or for both?

I appreciate any reply

Jitter is jitter. It's definition you probably know. You can use it for any regular signal. Clock jitter, data jitter, name your poison.

Jitter is any uncertainty in WHEN you decide what data you are receiving.
