1 Bicast is off, loopback is off on all ports, preemphasis is set to minimum on all ports, and equalization is set to minimum on all ports.
2 VICM is the input common-mode voltage.
3 Low power mode is obtained by following the steps identified in the Initialization Sequence for Low Power and LOS_INT Operation section.
4 EQ control pins (EQ_A, EQ_B, EQ_C) require 5 kΩ in series when DVCC > VCC.
