Notes: 15. Data decision threshold established after the receiver equalizer filters pulse overshoot and undershoot.

16. Jitter tolerance for 0 dB input signal level. Jitter tolerance increases at lower frequencies. See Figure 8.

17. See Receiver Jitter Tolerance Plot, Figure 8.

18. Guaranteed by design.
