The transmitter common mode voltage is fixed to
0.65 V.
This option is available if you want to use an
external termination resistor instead of the
differential OCT. Checking this option turns off the
transmitter differential OCT.
This option selects the transmitter differential
termination value. The settings allowed are 85 Ω,
100 Ω, 120 Ω, and 150 Ω.
