Deterministic jitter measured using K28.5 pattern at 2.488Gbps, V
ID = 10mVpp. Random jitter measured using K28.7 pattern at 2.488Gbps,
V
ID = 10mVPP.
10. Input is a 200MHz square wave, tr < 300ps, 50 load. VID ≥ 14mVpp.
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.
