(13) Typical values represent most likely parametric norms at V_DD = 2.5V, T_A = 25°C., and at the Recommended Operation Conditions at the
time of product characterization and are not guaranteed.
(14) Residual DJ measurements subtract out deterministic jitter present at the generator outputs. For 2.5 Gbps generator Dj = 0.0275 UI and
for 5.0 Gbps generator Dj = 0.035 UI.
