driver’s common mode voltage is higher than the MPC8536E SerDes reference clock input’s allowed range (100 to 400mV),
AC-coupled connection scheme must be used. It assumes the LVDS output driver features 50-Ω termination resistor. It also
assumes that the LVDS transmitter establishes its own common mode level without relying on the receiver or other external
component.
