assumes that the DC levels of the clock driver chip is compatible with MPC8533E SerDes reference clock
input’s DC requirement.
Figure 46
Since LVDS clock driver’s common mode voltage is higher than the MPC8533E 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.
Figure 47
Since LVPECL driver’s DC levels (both common mode voltages and output swing) are incompatible with
MPC8533E SerDes reference clock input’s DC requirement, AC-coupling has to be used.
