These ratings are those which if exceeded may cause permanent damage to the device. Operation at these or any other conditions in excess of
those listed under Operating Conditions below is not implied. Continued exposure to these ratings may reduce device reliability.
6.2 Operating Conditions
All specifications assume TA = 0°C to +70°C, VDD = VDDA = 1.8 ± 0.1V, VDDQ = 2.5 ± 0.2V, unless otherwise specified.

NOTE:
1. Applies for DC balanced data such as XAUI 8B/10B data. For data with long run lengths such as PRBS, DC offset compensation circuitry must
be turned off. The device default is for DC offset compensation circuitry to be turned on. See Table 3-17.
