Note 5: Random and deterministic jitter generation at 2.125Gbps is measured with 0.38UI deterministic jitter, and 0.22UI random
jitter (BER = 1 x 10-12) applied to the input. Random and deterministic jitter generation at 1.063Gbps is measured with
0.18UI deterministic jitter, and 0.08UI random jitter (BER = 1 x 10-12) applied to the input.
Jitter tolerance at 2.125Gbps is measured with 0.38UI deterministic jitter and 0.22UI random jitter (BER = 1 x 10-12) applied
to the input. Jitter tolerance at 1.063Gbps is measured with 0.18UI deterministic jitter, and 0.08UI jitter (BER = 1 x 10-12)
applied to the input.
