Notes:
7. Electrical signal.
8. With input signal VID > 50mVp-p and 50 load.
9. Deterministic jitter measured using K28.5 pattern at 2.488Gbps, VID = 10mVp-p. Random jitter measured using K28.7 pattern at 2.488Gbps, VID =
10mVp-p.
10. Input is a 200MHz square wave, tr < 300ps, 50 load. VID ≥ 14mVp-p.
11. This is the detectable range of input amplitudes that can de-assert SD. The input amplitude to assert SD is 2–8dB higher than the de-assert
amplitude. See
“Typical Operating Characteristics” for a graph showing how to choose a particular RSDLVL for a particular SD de-assert, and its
associated assert, amplitude.
