AC Characteristics
V_CC = +3.3V ± 7.5% or +5V ± 7.5%, T_A = -40°C to +85°C, input bit rate = 1.25 Gbps 2²³-1 PRBS unless
otherwise noted. Typical specifications are for V_CC = 3.3V, T_A = 25°C, unless otherwise noted.

signal of 20 mV_PP
Notes:
1. With V_{IN_DIFF} = 1 V_PP, typical times decrease as V_{IN_DIFF} decreases.
2. With V_{IN_DIFF} = 20 mVpp, typical times decrease as V_{IN_DIFF} increases.
