Note 1:
Measured as the minimum inner eye amplitude of the data signal at DIN that can be correctly regenerated. Input clock/data phase
and Data decision threshold optimized for sensitivity.
All specifications apply under the following conditions.
Input data pattern:

-1 PRBS
Input data rate:
2.48832 Gbps
Input clock frequency:
2.48832 GHz
Input data rise/fall time (20 %/80 %) >100 ps
Measured as the input clock/data phase range over which errors can be detected at RQ11-18 in 1:8 mode. Specification
applies under the following conditions:
- input data amplitude: < 375mV mean
1
-mean
0
- Input data rise/fall time (20 %/80 %) >100 ps
Hysteresis is the difference in the decision threshold that results in error free operation of the channel when the decision threshold is
first increased and then decreased and vice versa starting from a level that results in error free operation of the channel. The
hysteresis specification applies for both the ‘1’ and ‘0’ signal levels. The DIN input conditions are the same as those listed in note 1
above.
All amplitudes are differential peak-peak voltage
