Cables and Connectors
Supported transmission media include printed circuit board traces, backplanes, and cables.
Board Layout
The device should be placed as close to the interface connector as possible to minimize LVDS trace length.

Use cables and connectors with matched differential impedance (typically 100Ω) to minimize impedance mismatches.
Balanced cables such as twisted pair offer superior signal quality and tend to generate less EMI due to magnetic field canceling effects. Bal-
Avoid the use of unbalanced cables such as ribbon cable or simple coaxial cable.
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 coupling.
Separate the input LVDS signals from the output signals planes with the power and ground planes for best results.
anced cables pick up noise as common mode, which is rejected by the LVDS receiver.
