Random Jitter: Also referred to as “Gaussian jitter”, random Jitter is unpredictable electronic timing noise. Usually resulting from clock timing problems or random electronic timing noise.
Deterministic Jitter: This type of jitter can be predicted or determined. Reproducible, limited and may be periodic. Deterministic jitter can either be correlated to the data stream (data-dependent jitter) or uncorrelated to the data stream (bounded uncorrelated jitter).
Total Jitter: Calculated using a bit error ratio (BER), as well as a combination of random and deterministic jitter. The mathematical formula for calculating total jitter is Total jitter = Deterministic jitter+2*BER*Random jitter.
