Keep the LVDS and any other digital signals separated from each other to reduce crosstalk.
Use a four-layer PC board that provides separate power, ground, LVDS signals, and input signals.
Isolate the input LVDS signals from each other and the output LVCMOS/LVTTL signals from each other to prevent
Separate the input LVDS signals from the output signals planes with the power and ground planes for best results.
