V_{(single-ended p-p)max} = 3.3 V/2
V_{CM = 0.85 V}
VMAX = VCM + V_{(single-ended p-p)max} = 0.85 + 0.825 = 1.675 V (1)

Note to Figure 4–5:
(1) The absolute V_MAX that the receiver input pins can tolerate is 2 V.
Tables 4–7 through 4–12 show the typical V_OD for data rates from
600 Mbps to 6.375 Gbps. The specification is for measurement at the
package ball.
